Http error: 413 – Payload Too Large
The 413 http status code means that the request you made was too large. This can be due to the size of the file you’re trying to upload, or the amount of data you’re trying to submit. Either way, the server is saying that it can’t handle the request.
This error code is relevant in SEO because it can prevent your website from being indexed properly. If your website is returning a 413 error, it’s likely that Googlebot will be unable to index your site correctly. This can lead to lower rankings and less traffic.
To avoid this, make sure that your files are not too large and that you’re not submitting too much data at once.
