Cocolyze page analysis

What is page analysis ?

A page analysis is an in-depth SEO audit of a specific URL. It is useful to check the optimization of a landing page or a product page. The analysis reviews 70 criteria in four categories.


Content analysis allows to evaluate the editorial content of the page as well as the optimization for ranking, i.e. the ability of the page to be well placed and attractive on the SERPs.


The speed analysis is used to evaluate the speed of the page to be loaded, displayed and then interactive. All of the criteria evaluated help to improve the total time required for a page to be perfectly navigable.


The UX analysis allows to evaluate the optimization of the user experience in terms of mobile compatibility, user comfort, but also security and confidence in the page.


Robot compatibility analysis is used to evaluate the usability of the page for indexing, meshing and design.

How does it work ?

When a page analysis request is made, a robot takes over the page analysis and first checks the access authorization in the robots.txt file of the site. If it is authorized to access it, it launches a browser in a mobile environment, in the same way as an Internet user from a phone, and goes to the specified URL. It then loads all the resources of the page, renders it and evaluates the optimization of the page using JavaScript code and user interaction simulations.

The analysis of speed and potential gains in loading time and interactivity are based on Google's performance analyzer: Lighthouse. These metrics are derived from simulations and provide estimates of the benefits by correcting the relevant criteria. For various reasons (network traffic, machine load, etc.), these measures may differ from one analysis to another, but remain relevant because of the recommendations they provide.

How to use the report?

The Page Analysis report provides a Page Score ranging from 0 to 100 as well as a score for each category analyzed. A page is considered to be well optimized when a Page Score of 80/100 is reached. Under 50/100, its optimization is critical and it is likely to have difficulty positioning itself in the SERPs. A score of 100/100 is possible but is not essential. A score of more than 90/100 is generally sufficient to obtain a good ranking.

The report also provides a set of corrective actions to be performed by importance, so it is necessary to complete these corrective actions in the order in which they are listed.

The criticality of the analysis of a criteria is materialized by a color code:

  • red: when it is a correction to be implemented quickly
  • orange: when an improvement is needed
  • green: when the criteria has been validated
  • grey: when it cannot be applied

Each criteria is complemented by a brief explanation of its impact giving details of the incriminated elements as well as help button.

In addition, the key indicators "Core Web Vitals" used by Google for the evaluation of the optimization of the pages are given as an indication:

  • LCP, Largest Contentful Paint: time for which the most important element is displayed.
  • FID, First Input Delay: response time during a user interaction
  • CLS, Cumulative Layout Shift: representative score for visual layout stability

Good optimization!
