Can anyone guide me on checking whether my website’s structure is up to the mark or not?
A good start would be to check it with the W3C validators.
Many tools are available online to test the structure of a website. The oldest and most popular one is W3C Validator ( https://www.w3.org/ ) to check HTML and CSS errors/warnings.
Another best tool is Google Structured Data Testing Tool ( https://search.google.com/structured-data/testing-tool ).
Hope this is going to help you.
