When RYTE is showing the status code 403 ( or sometimes 900) then it's a clear indicator that the RYTE crawler is getting blocked by your server. The 403 status code means forbidden access. So the RYTE crawler is not allowed to access the requested resource(s). The easiest way to solve this issue is to whitelist the RYTE crawler's user-agent "OnPageBot".

Alternatively, you can whitelist the whole IP range of Amazon Webservice (AWS) Ireland, which we do not recommend because a lot of other crawlers are hosted by AWS.
