First show or zero first check performance
Why should the first point called zero? This is because the implementation is fully optional.
No need to check the program code or connect many external tools: it's just about the feeling of the tester, which might appear when the first visit to the website was tested. Things like this need no more than a few minutes.

This checkpoint is based on the assumption to analyze whether the portal value its availability or not. This conclusion can be verified by looking at the design of the site - does it solve the actual problem or have the fullness leaving an unpleasant and sometimes annoying impression?
What does it want to watch?
Division: How is the text on the site?
Tag: Is there an interactive tag?
Video: Does the video play automatically?
Animation: Does the site overflow with animated blocks?
This may be the earliest symptom improving web accessibility not taken into account when creating a site.
This is followed by a more scientific approach to the identification of more general bugs.
Button tab
Let's work with the tab button. Not all users use the keyboard and mouse to navigate websites - some can only use buttons on the keyboard.

Modern HTML supports keyboard navigation by default, but only if it is properly configured. But somewhere in the middle, some developers began to forget it, and sometimes simple manipulation as it was really impossible.
It should be noted separately that not all web browsers behave the same. On Google Chrome / Edge, the tab button behaves one by one, and with MacOS there are several exceptions (for example, the focus is only set for the input and button fields, but does not work with the link).
Automatic test instrument group
The important features of automatic software are simplicity and ease of use: With its help, you can get results that are directly reproduced. With their help, you can easily find the most easily repaired surface problems.
To find such bugs, you can use lighthouse products, which "catch" many accessibility problems, optimize SEO, and also provide comprehensive functionality to optimize performance.
Naturally, automatic programs cannot find all bugs - "capabilities" they include samples of 65 to 71% of the total defects.

Results
If, after completing all these manipulations, you cannot find a bug, then you do the job correctly! The website without accessibility of bugs is very rare today (according to a survey by a web portal, around 98% of the sites visited have some sort of accessibility problems).
Finding "big" accessibility issues associated, first of all, with a lack of knowledge, or "aesthetic victory over practical."

Working with the accessibility of websites is a useful and highly requested service that is more relevant than before in the age of digital popularization.
