[latest] how many google ads is allowed per page

For the last years there was a restrict limitations for
the number of allowed AdSense ads on a single page:
It was 3 ads for content units and 3 ads for link units.
(Some premium partners were allowed to serve up to
6 ad units)
In August 2016 Google updated this policy
You can now place an unlimited amount of AdSense
ads on a page following the recommendation:
This mean that all ads on your site, no matter if they
are based on AdSense or not, are taken into account
for the maximum number of allowed ads on a single
page.
There is no longer a strict number of ads limitation.
Its more important that you have no more ads on your
site than visible content.
An example:
Having more than 2 visible ads at the same time on a
mobile device is too much because this the would
highly likely exceed the visible content and would lead
to a bad user experience.
On the other hand on a large desktop monitor or tablet
it is ok to show 2 or more ads as there is more
available space.
How can you know if ads exceed your content?
“Should not exceed your content” sounds more like a
rule of thumb but we think you are on the save
side when you estimate the total space of your ads on
a single page and than compare it with the total
space of your content. You can also ask friends and
visitors if the ads on your site are irritating or not.
So you get a feeling about what is ok and what not. If
the user experience is fine and the total amount of
ads are not preventing a visitor from enjoying and
reading the content you should be fine.
How many AdSense ads are recommended?
Although there is no ad limit restriction and no upper
limit you should be aware of very short posts on your
site. Using a plugin and generating ads automatically
on all your posts could lead to a very bad user
experience and spamming of your own short posts
with a huge number of ads which quickly exceed the
total content.
To prevent this we recommend that you check your
short posts carefully and consider if the total visible
amount should be reduced. If you are using WP
QUADS you can easily do this by deactivating specific
ads on a single page:
If you are showing too many ads on a single page
you could run into less or no visible ads on your site.
“We may limit or disable ad serving on
pages with little to no value and/or
excessive advertising until changes are
made.”
So we suggest you keep less than 5 ads per page. We
usually enable 3 or 4 ads on our pages.
But you should do some testing:
Sometimes 2 ad units perform better than 3 ad
units.
Placing ads above the fold leads to better
performing.
A combination of text and image ads perform
better.
Anyway, this limit should be correlating to your own
website layout. If you have a lot of content and a huge
site it could be ok to enable more than 5 ads on your
site. The only thing that matters is the user
experience. Keep that always in mind!
How many AdSense ad units are you using on your blog?
As Google has lifted the 3 ads limit are you using more
AdSense ad units or do you retain to the previous
ad limit?
