Is your website using clean code
Check to see if your website has any HTML code errors by running it through a web standards validator. https://validator.w3.org/ then ask your web developer to help fix any errors.
Lots of websites have code which could make it difficult for both search engines and internet browsers to read. It is possible this code could break your site when viewed on different browsers and even worse could even confuse the search engines about your website.
Check your site and make the changes.
