Why not change the ad unit to responsive for mobile?

@ian, the CPM with those units are dreadful.

Someone just told me the Developer view on Chrome is "not a true representation" of a mobile view on your actual live phone (which is why my live Iphone 6 Plus view looks different), but what do I know.

Could you post your Adsense violation e-mail?

I am asking it because I Googled your site, and you are using 2 Adsense units above the fold (728x90 and 300x250), which is not best practice. Screenshot: [gyazo.com...]

If you want to keep ads above the fold, then I recommend remove 300x250 unit, and replace 728x90 unit to responsive ad unit with forced horizontal code. To force show horizontal banners only, then in your Adsense Ad code replace: data-ad-format="auto" to data-ad-format="horizontal". It will definitely fix you problem and remove violation.

For example:

<script async src="//pagead2.googlesyndication.com/pagead/js/adsbygoogle.js"></script>

<!-- ADS FORCED TO SHOW HORIZONTAL ONLY -->
<ins class="adsbygoogle"
 style="display:block"
 data-ad-client="ca-pub-xxxxxxxxxxxxx"
 data-ad-slot="xxxxxxxxxxxxxx"
 data-ad-format="horizontal"></ins>
<script>
(adsbygoogle = window.adsbygoogle || []).push({});
</script>

You can also use vertical, rectangle and maybe some more.

@ranka, they found no desktop violations because that 350 unit is NOT adsense. It's another network. Not sure why it's giving off a 300x250.

Oh my bad.

I had a violation warning from G on one of my sites.

It was the position of my 300 x 250 ads when viewed on mobile (a responsive site).

My understanding was that if "Fetch as Google" for mobile didn't show the ad ATF then it's OK.

I went ahead on that basis.

On some pages I moved the ad down so it no longer appeared ATF. Where that wasn't sensible I made the ad responsive so it showed as a smaller ad on mobile.

I marked the violation as corrected and haven't heard any more from then again.

But the whole thing about how G views a page and what is mobile and what is not is so confused. They never have nailed it down with a simple statement (which could be updated when things change) and it would be so simple to do.

I had an Adsense mod review, told me I was in the clear. This was their reply

""""""""On larger screens (longer) and tablets you may see more of the ad, although I don't see that as a problem since the ad is below the article. The idea is not to have the ad take up more space than the article and not to come before the article when it does.""""""""

Someone told me (not sure how true it is) that 300x250 BTF will actually have higher CPM than a 300x250 ATF (at least on mobile), because the view-ability is higher which in turn creates higher CPM as most people just quickly scroll past when it's ATF.

I got called on this last fall. I'm a bit insulted because my page they pointed out only did show a small part of a 300X250 ad right at the fold, so I need your representative.

Anyway, just two weeks ago or so I decided to start working on a new template and thought that before I did I would contact chat support and ask specifically what the minimum screen size was that could show any part of a 300x250 ad.

1) The chat person said they didn't know, and also stated that they had never been asked that question before.
2) They promised to ask a "specialist" for an answer and email me.
3) The reply was:
>>Our specialists do not have a specific width size that's defines a mobile screen, but they pointed me to the attached resources that seems to indicate anything above 340px would be okay to serve a 300x250.<<
4) Then later in the day they sent another email:
>>Quick update: I went around trying to get a few more opinions and it seems like 440px - 480px is a better bet. The iPhone 6 Plus (414px) and the Lumia (432px) are pretty large mobile screens that with a 300x250 would still violate our mobile implementation policy.<<

My CSS file had a media query breakpoint at 768 px, so I just went with that so to error on the safe side. Last fall I was on vacation when I got the warning. Pain in the A.

Our specialists do not have a specific width size that's defines a mobile screen, but they pointed me to the attached resources that seems to indicate anything above 340px would be okay to serve a 300x250

That response is very interesting and at the same time totally amazing.

G can potentially withdraw adverts from your site completely because you (not you personally) have placed a particular ad size in a position which they deem to be inappropriate. But they are not willing to define precisely or even roughly the inappropriate position.

Yes. yes, G can do exactly what they like because they are ads on their network, I know.

But in real life it's absurd. One specialist may deem a mobile screen size of x to be relevant and another specialist may deem it to be y. I just wish they would define the screen size so we can all keep to the guidelines.
