I rely on Adwords for new leads and for the last 6 days Google has suspended my site. I am told that the reason is that they receive a 404 error when viewing the index.php (front page) - http://18.104.22.168/
. However absolutely no-one else sees that error. The site has been active without pause since commencing. I even had one of their support staff tell me the problem was over when she accessed the site via her cell phone. Then she tried with her desktop, through probably one of the Google IP's, and told me that we were again getting the error.
The site has been running without incident for 15 months. However a day before the suspension I noticed what appeared to be an intruder trying to access the site and was concerned about a code injection. I reported this to the web host who blocked the particular IP. Please note we are using a shared server. I don't know if this blocking or intrusion has any relevance, but it's likely not to have been a coincidence that this event just preceded my suspension.
Once Google's suspension became known to me I asked my web host whether they had banned any of Google's IP's and they denied that being the case. 5 days later we unblocked the original intruding site still without any change in the site status. The Google support technician suggested that we had created a geographical block because they also had found inconsistencies in the error message. I was assured by my host that this is not the case.
So at the moment, I am holding discussions with Google technical support and my account manager but am continually being told that the case has been escalated and please be patient.
Does anyone have any idea how I can proceed from here? Perhaps there is something we can look for that Google and/or my web host has missed.
