With Google Ad Manager (GAM), you get the DoubleClick Ad Exchange and the DoubleClick for Publishers platform bundled together, this makes Google Ad Manager the best monetization platform for website owners.
If you’ve only ever monetized your site with Google AdSense, you might not have prior knowledge of the GAM truth be told, it’s quite less tedious to monetize your site with AdSense especially when it’s new.
What is Google Ad Manager?
Google Ad Manager is a premium publisher monetization platform that provides granular controls and supports a wide range of third-party ad exchanges and networks including AdThrive, Mediavine, Ezoic, and AdSense.
Publishers like me who don’t use Google AdSense but partner with premium monetization ad networks like Ezoic, Mediavine, and AdThrive have had a run-in with Google Ad Manager.

For a fact, you need to get your site approved on GAM before you can display ads from these premium ad networks even after you’ve passed their quality checks.
This mostly goes for New Ezoic users, they often get approved by the Ezoic Platform but don’t get approved by Google Ad Manager, this was a problem I faced back in the day.
How to get your site approved for Google Ad Manager
The rules for your site to get approved on Google Ad Manager (GAM) are pretty much the same as in AdSense in the sense that, if you don’t get approved on AdSense you’d never get approved for GAM.
I think AdSense is better from the Site Approvals perspective since they declare a reason why they’ve rejected your site but GAM doesn’t.
A few months back, I was trying to get one of my sites approved for Google Ad Manager via the Ezoic Platform and it first got rejected because of thin content which I immediately fixed.
The next rejection didn’t come with any response and this doesn’t help troubleshoot the issue.
All I did was apply for Google AdSense then and then I got rejected due to policy violations.
I now figured that when you have some policy violations on your website, GAM will not display any reason for rejection.
To fix the policy violation, I had to remove a Category on my site which reportedly housed content that Google Doesn’t like, I reviewed each article to remove the bad words and stuff.
I added a source link to every image I used on my site except the ones I created and I later got APPROVED.
What are the key takeaways from this story (why do sites get rejected from Ad Manager):
- Do not Copy Content from other sites
- Have enough content under each category like 10 articles.
- Do not use ‘bad’ words like ‘make money online’ and stuff in your articles. Trust Me!
- Whenever you pick a resource from anywhere on the internet, link to the source while using it in your article.
- The length of each article on your site should be > 500.
So, that’s pretty much all you need to do in order to get your site approved for GAM.
Google AdSense vs Google Ad Manager
If you’re a new publisher with a little less than 50,000 monthly visitors, you shouldn’t worry about Google Ad Manager, simply stick with Google AdSense for the time being.
But if your traffic is huge (higher than 50k per month) then you can go for GAM because it allows you to connect to Third Party Ad Exchange platforms and including AdSense, Ezoic, Mediavine, etc.

In any case, you can use GAM and Google AdSense on your website and see if it’ll boost your revenue (Most times it does, I still use both).
What is the Difference between Google Ads and Google Ad Manager (GAM)
The main difference between Google Ads and Google Ad Manager is quite simple… Google Ads is a platform that allows advertisers to bid for spots on Google Search either to get more traffic, Backlinks, or getting more sales while GAM is a product that connects publishers with third-party ad exchanges and networks so they can make money with their web traffic.
In simpler terms, Google Ads (formerly known as AdWords) is a product specifically made for Advertisers while GAM is a product for Publishers.
GAM can also be used by Advertisers who run Google Ads users with several ad accounts who run several Campaigns to to increase ad effectiveness and ROI.

How do I Sign Up for Google Ad Manager?
The best way to sign up for GAM is to get through with a third-party ad network like Ezoic, Mediavine, AdThrive, etc.
You need to understand that you only need your site to be approved once and you can signup for any site that requires it without having to apply again.
If you don’t want to apply for GAM from an Ad Network, you can head over to admanager.google.com and then signup, follow the next steps to complete the process.
Do note that you might not get approved if the email you’re applying with doesn’t have an AdSense account with an active domain, so don’t be freaked out.
Does GAM Cost Money?
Google A.M is a free Monetization tool for Publishers, it’s even helpful to advertisers who run Google Ads Campaigns, it doesn’t cost money and it’s free to use till date.
