What do you call a "long page"? I have sites with 67,000-275,000 WORDS PER PAGE that function with g ads without a problem. Just asking.

The problem with long pages is that often users never scroll to the end of the page so you end up with many ad impressions that are never viewed. What is your AVV? Do you have different ad-units for each ad on the page or are they all the same. In other words can you track ad metrics by ad position?

Using a second ad network to fill the unfilled ads is not going to work. Low demand is low demand, changing network is not really going to solve that problem. Moreover, there is no easy way to show AdSense when there is an ad, and show another network's ad when there isn't. So you end up having to decide to switch ad networks by ad position, which may result in lower revenue. You may see more ads, but you are unlikely to earn more money, essentially you will be giving away the ad space.

Great answer, Nick!

You might want to sign up for something like Microsoft Clarity that measures user behavior to see how far site visitors are scrolling on the page. Clarity has a Scroll Heatmap that shows how far visitors scroll down individual pages and I think it can even provide an overview of scrolling data for groups of pages.

Clarity can show you where users are lingering on a page and what parts seem to cause them to leave, which will provide you with insights into what parts of a page are popular.

All of the data can also be segmented by a couple dozen filters, like devices, etc.

Clarity is GDPR compliant so it'll work in Europe.

With more information about user behavior you may be able to make a better decision about your content and advertising.

Good luck!

Thank you very much, people, for your answers.

What do you call a "long page"? I have sites with 67,000-275,000 WORDS PER PAGE that function with g ads without a problem. Just asking.

The pages do not include that amount of words, but include several photos, so users must scroll down the pages for a long.
What do you mean for "without a problem"? Do your pages show more than 3-5 AdSense units per page?

The problem with long pages is that often users never scroll to the end of the page so you end up with many ad impressions that are never viewed.

Yep, it may be the reason. But pages include a form to leave comments at the bottom, and 0.1% of visits leave one comment and led me to think that a considerable share of visits reach the bottom of the pages. But, as proposed by @martinibuster, I'll use Microsoft Clarity to get sharp data. Are there similar services to Clarity?

What is your AVV?

It's virtually 100% for desktop and 50% for mobile. When desktop visits, I show AdSense units as soon as the page is loaded. But when mobile visits, I show AdSense units when user starts to scroll down. Yes, it's the reason of such low AVV, but it balanced AVV vs Pagespeed, and I get 100% Pagespeed with that solution. I've read the approach by @NickMNS at [webmasterworld.com...] and I'll try the option of loading the first BTF ad as soon as the page is loaded. I tried the option of loading the ads when users reached a specific position, but the AVV figures were very similar.

Do you have different ad-units for each ad on the page or are they all the same. In other words can you track ad metrics by ad position?

Yes, I have different ad-units. And the units showed on mobiles just below the fold, next to the first pic, offers the best RPM performance, even though they have lower AVV. Yes, it confirms your suggestion :-), and "Low demand is low demand", so I'll keep on analyzing the metrics.

One of my problems is that, when I insert the unit and the ad is not displayed, I leave the space blank to avoid 'Cumulative Layout Shift', so the user experience is poor. So perhaps it would be better not to include the units at the end of the pages.

Are there any errors in the console caused by Adsense?

I'm dealing with this issue on a friend's website. In that particular case ads are lazy loaded BTF, ads appear on some pages and not on others, and there are no errors in the console. Basically everything is working as it should, but still many ads go unfilled. So the root of the "problem" (is it a bug or a feature?) is happening on AdSense's end. In the case I'm working on, I fear that it relates to the "valuable inventory" policy (see link below for details). Basically there are more ads than content, at least from Adsense's perspective. We are using responsive ads with few restrictions on size, so each ad when displayed can be quite large and despite being well spaced out between block of content I believe that Adsense's algo may feels that the spacing is not sufficient. We are going to run some test over the next few days to sees if showing smaller ads will remedy the problem.

@Guarriman3 how is the relationship between content ads in your case? Do you show large ads?

Also note that the sites runs ads from a second ad networks and I am certain that it is contributing to the issue. Adding another ad network may increase revenue to some extent but it will likely exacerbate the problem (make it worse).

Are there any errors in the console caused by Adsense?

Nope, no errors. I call (e.g) six times the following JavaScript function

(adsbygoogle = window.adsbygoogle || []).push({});

and I see no errors, only blank spaces for the ads at the bottom side.

how is the relationship between content ads in your case? Do you show large ads?

Each webpage show 900-1,100 words, and tries to include 5-6 ads for mobile users. The largest size I show for mobiles is 300x250 with "data-full-width-responsive=true".

As mentioned, I use a sort of 'lazy load' for the AdSense ads, pushing the units just when the user starts to scroll down.

I'll try to include another proposed approach: by pushing the first unit after loading the page and the rest when the user is reaching their positions.
