9 Technical SEO Mistakes that Hurts your Ranking

What are the most common mistakes that don’t allow your site to rank better? Serpstat offers the answer, which is a recent study analysed more than 175 million pages and found over 300 million “errors” inside them! After that, they found 9 Technical SEO Mistakes that Hurts your Ranking.

Let’s see the most common together. In my humble opinion, not all the things listed below are real “SEO errors” (i.e. things that can somehow damage the ranking of a page or a website), but it is still good to fix them.

Here are 9 Technical SEO Mistakes that Hurts your Ranking


Technical SEO Mistakes that Hurts your Ranking

  • Pages with the canonical tag – 10.63% (I think it is understood that the tag was not implemented correctly, and therefore Google is facing two or more semi-duplicate pages)
  • Pages hidden at indexing by noindex – 4.68% (they could be pages put in noindex by the will of the webmaster, and not by mistake)
  • Iframe on the page – 4.01% (this is an obsolete HTML element, which can also impact on the loading speed of the resource)
  • Word number too low – 1.47% (although there is no optimal length for content, excessively short and inconsistent texts are usually synonymous with Panda)
  • Other (use of Flash elements on the page, pages hidden in robots.txt) – 0.35%


9 SEO Mistakes That Impact Your Site Rankings

AMP was announced by Google in 2015, with the aim of speeding up the use of content (especially via mobile). Serpstat’s study highlighted some errors in the implementation of this technology:

  • Deprecated items – 0.18%
  • CSS style sheet errors – 0.09%
  • Errors in JavaScript code – 0.08%
  • AMP not used – 0.02%


Common SEO Mistakes

  • Title / Description too long (15.48% / 7.71%) or too short (0.77% / 4.53%) (the advice, for the titles, is to stay under 11 words (about 65 characters) and between 100 and 320 characters for the description)
  • Duplicate Title / Description – 8.56% / 7.04% (title and description should be unique and original on every single page of your site; especially avoid identical titles!)
  • Title / Description missing – 0.59% / 8.47% (the title is among the main elements of a good on-page SEO; therefore it should never be absent; as far as a well written and captivating description is concerned, this is useful to take more clicks from the search engine SERPs)


Headings SEO

  • H1 absent – 4.69% (each page should have an H1, perhaps slightly different from the title)
  • Improperly nested headings – 2.13% (it would be good to respect a Hx hierarchy, going down from H1 to H6)
  • More than one H1 per page – 1.65% (although it almost never makes sense to put more than one H1 per page, it is NOT a mistake!)


What is HTTP Status

  • Server Status Code: 4xx – 1.01% (also for crawl budget issues, it is good to correct/redirect the pages that return a 4xx, especially if it is 404 errors; personally I manage them – on WordPress – thanks to the Broken Link plugin Checker )
  • Server Status Code: 5xx – 0.04% (these errors say that the server is unable to handle user requests; therefore, they must be corrected immediately, especially the 500)


What is HTTPS Certificate

  • The mix between HTTP and HTTPS content – 4.13% (indicates that the page includes both contents; it would be appropriate to pass the HTTP content under HTTPS)
  • HTTPS pages linking HTTP pages – 5.86%
  • Pages with insecure password entry – 0.59%
  • Name mismatch – 0.01% (the domain name for which the SSL certificate was registered does not match the name displayed in the address bar)
  • Obsolete TLS version – 0.01%
  • Use of HTTP Strict Transport Security (HSTS) – 0.04%



  • Too many external links – 0.01% (I don’t think it is a mistake, but exceeding with external links can actually disperse the juice in too many “streams”; also remember always to link high quality and non-spammy resources)
  • Links to pages that redirect – 2.98% (all links should point directly to the right resource, and not to an intermediate page that does redirects)


Page Speed Ranking Factor

The speed is the most important ranking factor (even (or especially?) On the mobile ). Therefore these three problems should be fixed:

  • Failure to use a browser caching system – 0.03%
  • Improved server response time – 0.02%
  • Compression not enabled – 0.01%


Remove HREFS Tags

  • Pages without Hreflang attributes – 0.94%
  • Hreflang that conflicts with page code – 0.58%
  • Invalid Hreflang values ​​- 0.16%
