When we talk about SEO mistakes, we tend to explain what needs to be done to improve the positioning of a page or a site in the search engine results pages. Because if SEO does have an impact on this positioning, let’s not forget that it only takes a few more or less insignificant mistakes to reduce to nothing the work done and your chances of improving your visibility on the web. Some of these mistakes are still made out of habit (or out of ignorance) and it is important today to get rid of them because they can be very costly.

To prevent your human and financial efforts to improve your ranking from being inadvertently wasted, I propose to review the 10 most common SEO mistakes to avoid as they can have a disastrous effect on your ranking.

1. No added value

First and foremost, you need to provide quality content to users before you can even think about performing well in the search engine results pages. No one will be interested in content that adds nothing. Be original (don’t copy, don’t tell the same story as others), be yourself and you will find your audience.

2. No strategy

SEO is a complex activity that involves different aspects such as on-page optimization, marketing, analytics, etc. If you don’t understand or only act on one of these aspects, then your approach will not be correct or efficient and you won’t get the results you want. The best thing is to define a global strategy that takes into account all aspects of SEO. Lastly, a referencing strategy is established at least over several months.

3. Do not put yourself in the place of the user

The latest updates of search engine algorithms clearly indicate that the user experience will be increasingly important in the ranking of a website. If you are looking to get a higher ranking for your site, it is important to focus on your users.

You don’t have to put all your efforts into analysing statistics or how to use meta tags to help search engines find you. I advise you to keep in mind that users come to a site if the content interests them, if the content is original and if the content really brings them something. Remember that you never become a writer for Google but for human beings.

4. Not being proactive

Search engine algorithms are constantly changing and it is very important to constantly adapt your pages, your site and your strategy to these changes. If your webmaster is slow to act on your site, it will probably have a negative impact on your SEO.

5. No duplicate content

Duplicate content is not just copying an entire page to display on your site. It is also having 2 identical URLs or 2 identical < title > tags. This type of error generates confusion and the friend Google not knowing which page it should index could be tempted to exclude from its results, all the pages presenting too marked or obvious similarities.

6. An unstructured site

Many people tend not to give this part of their website design the attention it deserves. But having a site structure that is understandable is very important for users and search engines. Don’t cut corners on this essential point.

7. No mobile friendly site

There are still too many websites in circulation today that are not “mobile friendly”, which in my opinion is a big mistake for two main reasons:

  • mobile traffic is counted in Google’s algorithm to calculate its ranking,
  • According to the latest estimates, more than one billion internet users connect via mobile devices as their primary device. And all studies show that this number will continue to grow in the years to come.

8. Too many 404 errors

This error indicates that the link on your page is not accessible. It is sometimes normal that some links end up being inaccessible, especially when quoting external sources. It is therefore important to follow these links and rectify them. Having too many 404 errors means that something is wrong with your website, which will have a negative impact on your ranking.

9. No deep links

It is very important to include deep links so that they can be displayed in the search results. While the home page is probably the most important page on your site, having deep links from your home page will give insight into the other pages of your site in the search engine results.

10. Keyword stuffing

This practice of using too many keywords on the page should definitely be banned as it really does have a very negative impact on your website’s ranking. Google considers that sites that still use this technique are trying to manipulate the ranking in its search engine results pages. Therefore, it will only hurt your ranking and degrade the user experience.


There are other mistakes that can slow down your progress in the search engine results page rankings. However, the ones listed above should really be avoided at all costs. So take advantage of having read this modest article to take a complete look at your site to make sure that everything is in order 😉
