After upgrading to v5 and moving to Cloudflare I see absolutely terrible adsense performance.

The traffic, ctr and other vitals are unchanged but ad quality and page RPM degraded beyond what I have seen in decades.

Is it possible something in the Cloudflare setup blocks adsense from crawling the content properly for contextual ads and we end up in generic, terrible quality ads?

For example when I try to preview a url in adsense, it can never ever load the url after the move to cloadflare. here is a screenshot. Does anyone else having similar issues?

Just looking at the example, that page is actually redirected to another one, which I suspend might be what you are seeing there. But there isnt anything specific. If you know what is visiting the site when it checks these things I can certainly take a look. Of course there are things like rate limiting in place to stop bots anything from hammering sites, but I wouldn't expect things like this to be happening here.

Thank you.

What do you mean? the full url can't be seen in the picture, but it is all there and there is no redirect on that url of any type that I know of. But this is far beyond a single url having an issue, every url has the same issue there.

Adsense bot name Mediapartners-Google and it clearly struggles to load/see urls. I suspect this is what causes all the issues. Were was zero issue before moving to cloudfare/v5.

What I am seeing is not simply bad performance but something beyond terrible, horrible.

Is there a way we can troubleshoot the adsense preview tool failing issue so I can define inclusion/exclusion zones etc. for the ads?

Does anyone else see much less ads being shown after the v5 upgrade and move to cloudflare?

Start by turning off Cloudflare. When you have multiple changes, you need to eliminate possibilities.

Cloudflare’s bot protection could be causing this problem very easily. If turning CF off entirely works, then start looking first at the bot stuff as the first reason.

If you visit that URL, it redirects to another page. Do you have another example which is not doing this? I want to ensure thats not what is causing the issue before I look any further

Switching off cloudflare is not possible

Marc, where does it redirect. I don't see the redirect in the header response.

So, this happens with every url in the website.

Cloudflare’s bot protection was also mentioned in a few reddit discussions on similar issues.

If you manually visit that URL and look at your address bar, you will see you are not at that URL

i don't a see a redirect neither in the address bar, nor in the page headers.

Of course the complete url is not visible in the screenshot like I mentioned earlier.

So to make 100% sure of what you are seeing here, if you manually visit that URL, you see that same URL showing in your address bar?

Yes, same url, no redirects anywhere that i can see.

Are you logged in or accessing it differently than a normal guest would?

I am logged in, but these urls are not for members only, do not act differently in any way for logged in members or guests.

Here is another example that the cloudflare setup for cloud hosted clients might have an issue. This is from google search console

@virap1 maybe this has something to do with your problem

Many Google Ads Accounts Not Serving Ads

Since March 1st, there are many Google Ads accounts that are not serving ads. The Google Ads forum is filled with complaints about this and as far as I can tell, I cannot find a single response fr...

Thank you. Wow, I did not know. My problem started exactly on the day in early February when I upgraded to v5 and the website started using cloudflare.

Im honestly not sure how you are seeing that. If you visit here

https://www.enotalone.com/article/dating/6-subtle-signs-shes-into-you-r2359

It directs to here

https://www.enotalone.com/article/health/improving-your-gut-microbiome-with-meditation-r2359/

The form on adsense does not show the full url, therefore it is also not in the screenshot I included. the url should be https://www.enotalone.com/article/dating/6-subtle-signs-shes-into-you-r23595/

That would certainly explain a lot. I cant say as to why they get they cant find the page though, as clearly its present. I've taken a look on our cloudflare to see if there are any events related to that page, and I cant see any showing up at all.

I think the useragent for the preview might be "GoogleAdSenseInfeed". So it will be great to make sure that is whitelisted along with all their ip ranges.

There also the issue of high server connectivity issue I shared above in a screenshot. On some days it shows as high as almost 20% and that is going to be an issue with a lot of websites.

We would need to know exactly what response is being received at that time. As I mentioned above, Im not actually seeing any blocks, so there isn't anything to unblock as such.

Because in cloud hosted setup we don't have access to our access logs i can't provide that information.

But you can certainly research the access log. I am sure there is a lot with that kind of high fail rate on multiple dates.

We need to know what response they are seeing on their end. I've taken a look at blocks here, and Im not seeing anything
