JavaScript errors that affect the search engine performance

Splitt stressed that many SEO specialists are still focusing on the initial website code, although Google uses a render HTML for indexation. The render HTML is what you see after JavaScript.

🧩 Martin has noted a common error with one-sided applications and websites using JavaScript: they often return 200 OK status for pages of errors. This happens because the server sends the answer 200 before JavaScript checks whether there is a page.

🚀 Another problem arises when sites ask users to grant a geolocation permission or other permits. Splitt says Googlebot always refuses such a request if the site uses geolocation (or similar requests) without a spare plan.

Splitt shared a few steps to help identify and correct JavaScript problems: Use the URL Inspectorate tool at Search Console, check the contents, look at the HTTP state codes, open the tools of your browser.
