⚡Why are SEO audits so important for positioning?

So you can understand the importance of an SEO audit, I am going to give you an example, which I am sure you will understand right away.

An SEO audit is like a medical check-up that you do to make sure everything is in order. If the doctor detects high blood pressure, he can get down to work and give you a treatment to follow. Same goes for SEO, we treat the issues we find during the site checkups. If, on the other hand, you can’t find any issues in your analysis, you will be able to keep everything running as it is, because your site’s health is in good condition.

In short:

An SEO audit is a check of the current state of your website to understand its loading speed, the titles, descriptions, the lack or not of H1 tags for example, the concurrence of duplicate content and another of the over 200+ factors that fully affect indexing, ranking and positioning in the SERPs.
