           <\/div>\n

          1. Writing Poor Quality Content Won\u2019t Rank Your Site Higher in SERP<\/strong><\/h3>\n

          The rules for collaborating with a dishonest SEO company apply when hiring an untrustworthy copywriter or buying content from who knows where.
          \n\u00a0
          \nHow can you avoid this mistake?<\/strong>
          \n\u00a0
          \nQuality content might be a hard thing to achieve, as it requires work, just like other valuable practices. I mean some people are doing it, why can\u2019t you find someone fair to work with? You must search for a copywriter on authorized sites, not a freelancer that you saw on a site with a high amount of commercial ads.<\/p>\n

           <\/p>\n

          \"SEO
          \n\u00a0<\/p>\n

          The relation between you and the SEO company must be based on trust. All the hard work will be rewarded, and you won\u2019t risk getting penalized for black hat SEO techniques<\/a>.
          \nYou need to get rid of all your poorly written content.<\/p>\n

           <\/div>\n

          2. Not Researching Your Niche and Keywords is Bad Practice <\/strong><\/h3>\n

          Not researching your niche and not researching for keywords opportunities is not only an SEO mistake but also reflects a bad management practice. If you don\u2019t know your niche, you might bring irrelevant visitors to your site and increase the bounce rate.
          \n\u00a0
          \nHow can you avoid this mistake?<\/strong>
          \n\u00a0
          \nBy searching and discovering your niche you will find out what its needs are. Therefore this will help you to do a deeper analysis to understand how to trigger the intent. After a rigorous understanding, you could search for keywords to bring them onto your website and finally make them convert.
          \n\u00a0
          \nAnother important thing you need to do is to understand which are the keywords that sell and the ones that inform the user.
          \n\u00a0
          \nYou could bring value to your keywords if they are chosen and optimized correctly.<\/p>\n

          <\/span>
          \n\u00a0
          \nOn the web you can find lots of tools that can help you to choose the right keywords or get ideas for new keywords; the most used one is           Keyword Planner<\/a> offered by Google. You can spy on your competitors to see how they are doing and improve your business online by taking advantage of what they are missing. One way you can do that is by using Brand Mentions<\/a>, a free tool designed to help you with competitor spying.<\/p>\n

           <\/div>\n

          3. Optimizing for the Wrong Keywords Will Never Get You Results<\/strong><\/h3>\n

          Wrong keywords might be those that fall into another activity profile. For example, let\u2019s say I sell toothpastes and I have a blog where I write weekly. On my blog, I have articles where I used keywords like \u201chow to choose a toothpaste\u201d, \u201ctoothpaste for sensitive teeth\u201d and so on. At one moment I find some interesting news about toothpaste for dogs and I want to write an article about that, using \u201ctoothpaste for dogs\u201d as a keyword. I must think twice if it\u2019s appropriate. Perhaps, I shouldn\u2019t as my audience wouldn\u2019t be interested in that matter; or even if it were, it would probably apply to a very narrow niche.
          \n\u00a0
          \nAnother type of wrong keywords could be those that are not connected at all with your website profile or the interest of the user. For example, you have a site about cosmetics and news about the Pokemon game is trending in the world wide web . I don\u2019t recommend you to write about that just to receive traffic on your site because it\u2019s irrelevant. I’m not saying don’t to take advantage of the trends, but you must be smart and see if you can do that because you could quickly become an epic fail and pollute your website.
          \n\u00a0
          \nYou will confuse the visitors, and they might never come back to your site.
          \n\u00a0
          \nHow can you avoid this mistake?<\/strong>
          \n\u00a0
          \nAfter you’ve come to know your niche and searched for the keywords, make sure they are relevant. Optimizing for the wrong keywords will only \u201cbring\u201d you traffic loss.<\/p>\n

           <\/p>\n

          First, you need to think about the topic and then search for the best-suited keyword after you analyze very well the suggested keywords list (try Keyword Planner from Google for that). It is highly important to see if the keyword you chose is relevant for your users\/customers. Is it something they might be interested in? Is it suitable for your content? You will never get the results you want if you target the wrong keyword.<\/p>\n

           <\/div>\n

          4. Using Similar Content in the META Tags<\/strong><\/h3>\n

          Another common mistake is using similar content in the META Tags. These tags include meta titles, meta descriptions, and even meta keywords. It is hard for the search engines to choose what page to show from your website if you are using the same keyword or title. Remember that Google lists the results for your query in almost a second. Google might not show the result you want for that query. And another thing you should remember is that Google values uniqueness.
          \n\u00a0
          \nHow can you avoid this mistake?<\/strong>
          \n\u00a0
          \nYou should register your site with Webmaster Tools (know now as Google Search Console) to see the pages which have duplicate meta description, meta titles and this can help you to write different content on each page.<\/p>\n

           <\/p>\n

          \"Google<\/p>\n

           <\/div>\n

          5. Missing Title Tags and Meta Descriptions<\/strong><\/h3>\n

          You should always write title tags and meta description otherwise, you miss being shown correctly in SERP and increase your CTR. You can lose traffic and ranking if you don\u2019t optimize these two elements. They are crucial because if they are written correctly, you can persuade as many visitors as possible to enter your site. So little can do so much. So why not try to do something if it\u2019s for your own good.
          \n\u00a0
          \nHow can you avoid this mistake?<\/strong>
          \n\u00a0
          \nIf you are using an open-source content management system such as WordPress or Blogger, you can install plugins to help you to optimize your content better. The most used one is SEO by Yoast, and it looks something like this:<\/p>\n

           <\/p>\n

          \"WordPress
          \n\u00a0<\/p>\n

          If you have a site written using programming language, you should have HTML tags for titles, descriptions, and keywords.<\/p>\n

           <\/div>\n

          6. Missing Alt Description for Image Optimization <\/strong><\/h3>\n

          Not having alt descriptions for images is an SEO mistake because you will lose substantial traffic from image search. And it also shows you act like a novice.
          \n\u00a0
          \nIf you are using alt description, you can guide the search engines understand what is that picture about and “help” it to appear in the Image search for the right keyword.
          \n\u00a0
          \nImages have an important role on a page because they are visually more attractive and if they are properly optimized, they could have higher visibility than the content. You can see an example of this kind below. The first screenshot is for the query search, where you can see that \u201cbran Schloss\u201d is found on page 3 in Google.
          \n\"Keyword<\/p>\n

          The second screenshot is for the image search, where you can see that the picture for the same keyword \u201cbran Schloss\u201d, corresponding to the same site, is found above the fold.
          \n\"Image
          \n\u00a0
          \nThe best practice would be to have a strong content, correctly optimized and supported by an optimized image. I encourage you to use the keyword you\u2019d like to rank for in the name and alt description of your image.
          \n\u00a0
          \nHow can you avoid this mistake?<\/strong>
          \n\u00a0
          \nYou should include the alt description for every picture, and you can do that by simply add alt=”here you can write your alt text” to your image tag. This is an example:
          \n\u00a0
          \n\"image
          \n\u00a0
          \nIf you have an account on WordPress or Blogger, it is much easier. Here is an example of how you can write your alt text in WordPress:<\/p>\n

           <\/p>\n

          \"Image<\/p>\n

           <\/div>\n

          7. Optimizing Just for Short Tail Keywords Won\u2019t Bring You Traffic<\/strong><\/h3>\n

          There are two types of keywords: short tail (1-2 words) that are usually broad keywords and long tail<\/a> (more than 3) that are more specific.
          \n\"short
          \n\u00a0
          \nIf you have a site optimized just for short tail keywords, you might not get the traffic you want because the number of results for that query is vast. You shouldn\u2019t use very specific keywords either because nobody might look for them.
          \n\u00a0
          \nHow can you avoid this mistake?<\/strong><\/p>\n

           <\/p>\n

          You should search in the Keyword Planner for the best-fitted keyword for your type of content. Also, you can start typing the keyword in the search engines to the see the suggestions and the number of results for it.
          \n\u00a0
          \nAnother thing you could do is spy on your competitors, see what keywords they are using and discover on what page they are ranking.
          \n\u00a0
          \nI understand that it is hard to find the right keywords, but if you do your job right, you\u2019ll be thanking yourself later.<\/p>\n

           <\/div>\n

          8. Ignoring Local SEO Won’t Differentiate You from Your Competitors <\/strong><\/h3>\n

          Why is ignoring local SEO a mistake you might ask? Well, when you or a friend of yours search for a restaurant, for example, don\u2019t you look at the physical location or opening hours, or maybe a phone number to make a reservation. You can find on Google Maps all that information.
          \n\u00a0
          \nI searched for \u201crestaurant in Boston\u201d on Google and here\u2019s how the first-page result looks like:
          \n\u00a0
          \n\"Restaurant
          \nYou can see that the first results are from Google Maps where you can choose from a list of restaurants, based on location, reviews of whatever choices you might have.
          \n\u00a0
          \nIf you search for a particular place\/restaurant\/business you could find a lot of information right from Google, without having to make a single click on a URL. Here is an example of this kind for \u201cNeptune Oyster\u201d, a restaurant in Boston.<\/p>\n

           <\/p>\n

          \"Neptune<\/p>\n

          So yes, it is a mistake to ignore local SEO because you might lose an important quantity of customers in your physical store, restaurant or business and visitors on your site, ultimately.
          \n\u00a0
          \nHow can you avoid this mistake?<\/strong><\/p>\n

          <\/span>It\u2019s quite simple, despite what others say. You should create a Google My Business<\/a> listing and fill out the information. Also, you can optimize your landing page with local SEO keywords within your title tag, H1 tag, URL, page content and image alt description.
          \n\u00a0
          \nAnother best practice is to create accounts on Yelp and Tripadvisor to receive reviews. You can, also, search for other authority sites that offer local business listing.<\/p>\n

           <\/div>\n

          9. Optimizing for Extra Long Tail Keywords with No Traffic <\/strong><\/h3>\n

          Remember what we\u2019ve talked earlier about that type of keywords that are too specific. Well, here we are again with an extensive explanation. Let\u2019s say you have a business and sell trips in Transylvania; you shouldn\u2019t use keywords such as \u201dhaunted hunyad castle tour transylvania\u201d. They are too long, too specific and you can see in the Keyword Planner tool the query has almost no searches on Google.
          \n\"haunted
          \n<\/span>
          \n\u00a0
          \nHow can you avoid this mistake?<\/strong>
          \n\u00a0
          \nUse Keyword Planner to find keywords that are relevant and have searches, so you can receive traffic on your site. In addition, you can search on Google for that specific keyword to see how many results it shows you.<\/p>\n

           <\/div>\n

          10. Leaving Title Tags Automated Won\u2019t Help You Increase your CTR <\/strong><\/h3>\n

          Automated Title Tags are those types of titles that are generated instantly after you wrote the title of your topic. You can change them for a more compact version of it. Title Tag is an essential element in the SEO world. Set it right and optimize it correctly.
          \n\u00a0
          \nHow can you avoid this mistake?<\/strong>
          \n\u00a0
          \nFor example, if you have a post titled \u201dBest Case Study of 2016: 10 Inspiring Tips to Help You to Start Writing Content Your Audience Love\u201d you should change it to something like that: \u201c10 Tips to Help You Write Content Your Audience Love\u201d.
          \n\u00a0
          \nYou can have an idea about how the first title will look in the SERP by checking the next picture:
          \n\"Title
          \nThis is the preview for the second title:<\/p>\n

          <\/span>
          \n\u00a0
          \n\"Title
          \nIf you keep it up to 60 characters you are safe, it will appear nicely in the search results, and you won\u2019t risk getting cut off because it doesn\u2019t exceed the limit.<\/p>\n

           <\/div>\n

          11. Writing Short Form ContentWon’t Build a Long-Term Relationship with Your Customers<\/strong><\/h3>\n

          If you write short content (maximum 400 words) with little information about a topic, it could be a mistake because you might lose quality links and traffic. We\u2019ve made a study<\/a> on this exact matter, to see which type of content ranks better: long or short. Except the fact that you might be placed on better ranks, the longer the content, the more you give them the feeling of trust and the more you can help them by answering their questions.
          \n<\/span><\/p>\n

          How can you avoid this mistake?<\/strong>
          \n\u00a0
          \nThe most important thing is to create useful and long form content to say everything you know about that topic. You must find out how long your content should be for your audience and keep it entertained.<\/p>\n

           <\/div>\n

          12. Optimizing Multiple Pages for the Same Keyword – content cannibalization <\/strong><\/h3>\n

          To someone who is an SEO novice, keyword cannibalization might happen. It is a mistake because you can confuse the Google bot, who might not choose the right piece of information to show in the search results.
          \n\u00a0<\/p>\n

          \"googlebot-confused-cannibalization\"

          Picture taken from https:\/\/d1avok0lzls2w.cloudfront.net\/img_uploads\/googlebot-confused.gif<\/p><\/div>\n

           <\/p>\n

          How can you avoid this mistake?<\/strong><\/p>\n

          You must be careful when you optimize your content. I encourage you to use a \u201crel=canonical element\u201d. Also, you could try using SEO by Yoast to optimize your content because it tells you if you have chosen a keyword for that article and that it has been used once before so you can avoid keyword cannibalization.<\/p>\n

           <\/div>\n

          13. Not Adding Keywords in the Heading Tags<\/strong><\/h3>\n

          This can also be a mistake because search engines make a connection between the content and the words written in the heading. H1 is the most important type of heading, and you should use it just once during a piece of content.<\/p>\n

          How can you avoid this mistake?<\/strong>
          \n\u00a0
          \nThis is how HTML Headings look like:
          \n\"HTML
          \nAnd that is how you can see them:
          \n\"HTML<\/p>\n

          <\/span>
          \nYou should add keywords in your heading tags whenever possible. It helps you to rank better, gain quality traffic on your site, and it is a sign of relevancy and good optimization. However, you must not abuse this practice.<\/p>\n

           <\/div>\n

          14. Stopping Search Engines from Crawling Your Site<\/strong><\/h3>\n

          There could be cases when you accidentally stop your site from being crawled by the search engines because of a robots.txt error<\/a>. It can happen when you launch a site and forget to remove its blocking. There are cases when Google decides to show your site even though there is a no index meta tag in the page’s HTML code.
          \n\u00a0
          \nFormer Head of Spam Team, Matt Cutts, talks about this particular situation in a video. He says that the Department of Motor Vehicles (DMV) from California had a robots.txt file that blocked all the search engines. Google saw that a lot of people linked to this page with the anchor text \u201cDMV\u201d and when someone typed the query in the search results Google discovered that the site was relevant for the users. Therefore, the page appeared in the search results even though the page wasn\u2019t crawled.<\/p>\n

           <\/p>\n\n

          How can you avoid this mistake?<\/strong>
          \n\u00a0
          \nYou need to check your robots.txt file to make sure it\u2019s correct and, also, because most of these files include sitemap.xml that increase the speed of bots crawling.<\/p>\n

          15. Deindexing Your Website Needs to Be Solved<\/strong><\/h3>\n

          Usually, deindexing your site might happen when you\u2019re updating your site and fail to place the no-index tag in the head of your site:
          \nThis is just an example:

          \nHow can you avoid this mistake?<\/strong>
          \n\u00a0
          \nYou must be very careful to the changes that your site goes through. Make sure you check the elements of site code. Some tools can help you with that and show you what changes you\u2019ve made. You can search for Versionista, OnWebChange or NetWatcher.<\/p>\n

          16. Migrating Site without Using Redirects<\/strong><\/h3>\n

          If done right, 301 redirects have the ability to solve some big problems for a site. They offer an elegant design instead of an obsolete one, have a better user experience and most important, keep the link juice.

           <\/p>\n

          And yes, it\u2019s a mistake if you want to migrate your site and don\u2019t use redirects because you\u2019ll lose your visitors and all the link juice.<\/p>\n

          How can you avoid this mistake?<\/strong>
          \n\u00a0
          \nYou need to check all the URLs that are redirected. You can do that by accessing your server. Verify the report, download the excel and look after the URLs using VLOOKUP function.<\/p>\n

           <\/div>\n

          17. Creating Loop Redirects Is Creating Bad User Experience<\/strong><\/h3>\n

          Having a loop redirect can happen if it is a server configuration issue and a page has multiple redirections. This issue can appear in browser with this message \u201cError 310 (net::ERR_TOO_MANY_REDIRECTS): there were too many redirects\u201d.
          \n\u00a0<\/p>\n

          \nHow can you avoid this mistake?<\/strong>
          \n\u00a0
          \n<\/span><\/p>\n

          One solution, also suggested by Google, is to delete cookies. Another solution is to check\u00a0your .htaccess file, because if you don\u2019t keep this file clean, it might crush your website really bad. You should look for too many redirecting codes and try to clean the file.<\/p>\n

           <\/div>\n

          18. Canonicalizing Irrelevant URLs to Avoid Content Duplication<\/strong><\/h3>\n

          Canonicalization is a hard word to pronounce, but a practice not so hard to use. If you have a business about cats and your site is thecat.com, but also www.thecat.com, www.thecat.com\/ you need to help Google understand which is the original content with you rel=canonical tag. Not using the tag you might encounter, involuntarily, content duplication.
          \n\u00a0<\/p>\n

          \"canonical-tag\"

          \nHow can you avoid this mistake?<\/strong>
          \n\u00a0
          \nYou can easily step out the content duplication area by using this code for every version of your website URL to redirect them to the original site.

           <\/p>\n

          Because search engines rely on offering better user experience, they rarely show two versions of the same website in the search results. There might be those particular cases when you search for a query, and the search engines show maximum two results that send you to the same website. That happens ONLY when the site has high authority, and it\u2019s relevant to your query (but that only the search engines could decide based on their algorithm).<\/p>\n

           <\/div>\n

          19. Blocking Content on CDNs Leads to Traffic Loss<\/strong><\/h3>\n

          CDN stands for Content Delivery Networks. We must not forget that using CDN improves the speed of a site. But, if it\u2019s not properly implemented you might risk blocking the crawling of the subdomains entirely.
          \n\u00a0
          \nNowadays, it\u2019s common for organizations to block domains or IPs. We live in a world that changes a lot from day to day, and there are political, geographical, cultural boundaries and much more. But, if you blocked content on CDN and didn\u2019t want to, you will lose traffic.
          \n\u00a0
          \n How can you avoid this mistake?<\/strong>
          \n\u00a0
          \nTo avoid this mistake, you should be careful and use the SEO setting offered by CDNs and include the canonical tag to the duplicated files through CDNs\u2019 different domains. If you want to be sure if the Googlebot can access the files you can use the feature \u201cFetch as Google\u201d from Google Console.<\/p>\n

          20. Depending on Ajax & JavaScript to Feature Content on Websites<\/strong><\/h3>\n

          Using AJAX to display content was a big hit back in the days, but in 2015 Google announced <\/a> that it would no longer support the AJAX crawling scheme because it uses too many resources to render the websites and it was a challenging practice. It\u2019s not a question whether Google can or cannot crawl the sites using AJAX or JavaScript, but there is a slight possibility it will show HTMLs with no content. It will look something like that:
          \n\"HTML
          \nDepending on AJAX & JavaScript to feature content on a website is not necessarily a mistake, but it shows you are not offering good user-experience and it\u2019s an example of bad practice.
          \n\u00a0
          \nHow can you avoid this mistake?<\/strong>
          \n\u00a0
          \nYou should rely on HTML and not on scripts. Google suggests you use the           principles of progressive enhancement<\/a> to built content:<\/p>\n

          \n

          If you’re starting from scratch, one good approach is to build your site’s structure and navigation using only HTML. Then, once you have the site’s pages, links, and content in place, you can spice up the appearance and interface with AJAX. Googlebot will be happy looking at the HTML, while users with modern browsers can enjoy your AJAX bonuses.
          \n\u00a0
          \nOf course, you will likely have links requiring JavaScript for AJAX functionality, so here’s a way to help AJAX and static links coexist: When creating your links, format them so they’ll offer a static link as well as calling a JavaScript function. That way you’ll have the AJAX functionality for JavaScript users, while non-JavaScript users can ignore the script and follow the link.<\/p>\n<\/blockquote>\n

           <\/p>\n

          For example:

          21. Having a Slow Website Speed Could Drastically Decrease Conversions<\/strong><\/h3>\n

          Having a slow website speed is a mistake because you will create a bad user experience which will lead to losing traffic and eventually to killing conversions. The reasons why you have a slow site speed could be:<\/p>\n
