Is Ad Inventory Increasing?

I posted the quote below in the September Earnings thread too, but I wonder if others are seeing an increase in available ad inventory.

We commonly see comments here about more publishers running more pages with more adblocks and thus reducing the number of ads available for any given site, so I thought this was interesting.

My page views are actually down a bit from last September, but ad impressions are up a little, as is income.

The ad impressions going up is a surprise, it means G is more likely to fill more adblocks than a year ago. So instead of running just 2 or 3 ads in a 300x250 block they may be running 3 or 4 ads.

That's opposite of what my general impression had been.

Anyone else seeing an increase in ad impressions on the same or fewer page views, with the same or fewer available ad slots per page?

I haven't noticed any difference, good or bad. If there are differences in inventory that might affect impressions, those differences are likely to vary by topic and keyword.

I wish ad inventory were to increase. I seem to get the same old stupid "MFA style" bogus ads appearing all the time.

It would be nice to see some new (and legit) advertisers for a change!

One thing that reduces the number of ads shown is the slowness of Google's server. If the visitor just takes a quick look at a page, a page in which there are 3 ad units, it's possible Google will never serve the second or third ad units.

IF, Google has improved their server's performance, more ads would be displayed on your site even though the page impressions remain constant.

Having Custom channels on each of three ad units on the same page will almost invariably indicate fewer impressions for the second and third ad units.

Boosting your web site's performance may help here as well, allowing more bandwidth for Google's ads to be served.

Sept-Dec is a good time for advertising and we have seen a major improvement in eCPM (TOS bans me for disclosing actual numbers).
