How can you analyze a website for SEO?

Question

PHP

Hey! How can I implement a service like here https://seo-akademiya.com/audit/ ?
You need to make the user enter a link to the site and his mail. Then the service makes an analysis and sends it to the user's mail.
And here I have questions.
How can such an analysis be done? Is there some kind of api for another service or parsing from another site?

Answer 1

1) Google the checklist for verification / consult with a SEO specialist and compose it yourself
2) Send a link to the page to your handler, parse it with some kind of parser like DiDOM or native DOMDocument (hardcore if you want), check that the received page matches your checklist. You can also run pagespeed through their api.
3) Make a report, send data
4) ???????
5) Audit completed

Answer 2

lazy to google? finished api - this is the service))
