Google AdSense Optimization Tips For Better Revenue & Better UX

Google AdSense is the most widely used ad product used by publishers across the web. Due to its wide availability, it has increased Google’s ability to further attract top advertisers to its platform. This means that AdSense has remained a powerful ad monetization tool for most publishers.
However, due to the complex nature of the ad ecosystem, many publishers are often missing best practices and other Google AdSense optimization tricks on their websites.
Researchers have estimated that nearly 80-90% of AdSense users are lacking some of the most common optimization tips and best practices. Below, I’ll outline what these are and how to implement them in your AdSense account.

The best way to start is by doing a FAQ around some of the most common terms and questions AdSense publishers ask.
I’ll start here and provide advanced insights to those who may be looking for a more detailed edge in how they monetize their web properties with AdSense.

What is Active View CPM?

Active View CPM is when at least 50% of an ad is displayed on the screen for 1 second. This is important to publishers; as it is a core metric advertisers use for determining viewability.
It is one of the ways publishers can earn money from display ads.
Many advertisers will only bid or buy viewable ads. This is one — of many reasons — why visitor engagement directly affects ad rates.

How does Google AdSense define a pageview and CTR?

In AdSense, a pageview occurs anytime a page is loaded with ads. CTR defines the click-through-rate percentage of a pageview’s ad impressions to total user clicks.
Ad impressions are accumulated as advertiser ads are placed in different areas of a publisher’s site as a visitor browses through pages.
Having a lot of pageviews that generate a large number of non-viewable ads with very low CTRs (or 0% CTR) could be indicative of a high rate of navigation bounces.

Research shows that lots of short or accidental pageviews (like those generated from navigation bounces) can drive down the value of ads on a publishers page over time; resulting in lower ad earnings.
The goal of a publisher should be to balance visitor engagement, visitor behavior, and ad earnings. These things need balance to ensure a proper experience for visitors and a positive overall outcome for advertisers long-term.
In fact, research shows that user experiences may be the paramount factor in total publisher ad earnings.

Google AdSense optimization best practices

According to Google, publishers should seek to blend, complement, and contrast ads and content on the page. 
adsense ad styles
When customizing ad styles in AdSense, use colors that already exist on the site, but don’t match backgrounds and borders. Choose colors that stand out against the background.
Maximize your ad space with multiple ad units. There is a large inventory of ads types, styles, and sizes that can be displayed. Limiting these selections to what you “think” may work best could be limiting ad earnings, and also negatively impact visitors.

What are the most popular AdSense ad sizes?

The most popular AdSense ad sizes are not necessarily the ones that are best for revenue and user experience; however, they often have some of the largest competition for advertisers for fill space. These includes:
popular adsense ad sizes

  • 336 x 280 large rectangle
  • 300 x 250 medium rectangle
  • 728 x 90 leaderboard
  • 300 x 600 half page
  • 320 x 100 large mobile banner

If you want to drive up competition for ad space on your website, you should consider more than just what ad sizes advertisers are seeking to place most. Publishers should consider the effect that ads have on other ads.
Research presented at Google suggests that showing fewer ads can actually increase revenue, but only if it is done using data, not subjective opinions.
Display both text and image ads. Limiting ad types to a single form can really limit the amount of competition for a particular ad placement.
In fact, we’ve learned that showing certain visitors an image ad and others a text ad is actually the optimal way to approach this issue (text ads load faster, so work better for certain users, but not for others).

Should you use AdSense filters?

Filters rarely do anything to increase earnings, but can help publishers filter out certain types of ads that may conflict with the content on their website.
It is strongly encouraged that publishers grossly limit filter use; as it can limit the ad earnings of a site.
adsense ad filters
One of the best ways to figure out how different ad category filters are affecting visitors is to test them on your visitors.
Turn on the filters you think might improve experiences for visitors, measure bounce rates, time on site, and pageviews per visitor better yet engagement time. Then, turn off all the filters and measure again.
Let objective data tell you about the effectiveness of AdSense advertiser filters to improve visitor experiences.

Ensure Google policy compliance and avoid long-term issues

Do not disguise ads. Keep ads looking like ads. Being deceptive about where ads are placed (i.e. close to buttons and navigation) will generate false clicks; which can lead to you getting banned.

Furthermore, make sure you don’t encourage accidental clicks.
I’ve seen users banned in AdSense for telling visitors, in a tongue-in-cheek format, to support the site and click some ads.
You can read more about what Google policy says, and how they ACTUALLY enforce these violations here. I went into detail regarding how these things are enforced.
Outside of Google policy, ensure ads are not interrupting a visitors ability to actually consume content (i.e. breaking up words, covering content, etc.).
Make sure the site is easy to navigate. Navigation plays a huge role in both the quantity and quality of pageviews generated from each user session.
We did some tests on website redesigns and found that usability optimizations generally end up being way better investments of time.

Adding AdSense Search for search monetization

A lot of publishers fail to leverage the AdSense Search monetization feature inside of AdSense.

It’s as easy as adding the AdSense search box to your sites pages (or maybe even just your homepage).
Some publishers see increased ad earnings from adding this feature to their websites. AdSense Search allows publishers to earn a percentage of revenue from search ads that generate revenue from searches that occur from the installed Google search boxes on the publisher’s page.
Placing this in the publisher’s navigation bar is typically one of the best ways to do this.

Testing is what really increases AdSense ad earnings

While A/B testing is good. It has what we call a losers dilemma.
ab testing user engagement
A/B testing can help publishers get a rough idea around ad density and ad locations, but it is just that… rough.
Understanding which users prefer A and which users prefer B inside of a test presents publishers with a terrific proposition. Give visitors that performed better with A (bounced less, generated more ad earnings) result A, and give the visitors that performed best with B result B.
Data suggests that less testing and more visitor segmentation is actually more helpful than lots of testing with static implementation… meaning, don’t test something and then deliver everyone the same thing.
One of the best AdSense optimizations you can make is to adjust ad placements based on how different visitors react to varying ad densities and placement types.
Run tests and then figure out how to distribute the variables based on how test subjects performed — according to their preferences.

Creating custom channels in AdSense

Another way to create value in publisher ad inventory (ad space) is by creating custom ad channels.
These are groupings of ad units that are used to track the performance of similar placements ex: ad sizes and colors, locations of ads on page, page topics.
adsense custom channel
These can be turned into targetable ad placements that advertisers can — and may want to— target.
Publishers can create up to 500 custom channels in AdSense.

AdSense errors and issues causing drops in revenue

These are common reasons why AdSense earnings might be declining.
A common reason is robots.txt or Googlebot being blocked from crawling a page. If Google can’t crawl a page, it won’t let AdSense display ads on that page.
We talk about all the most common errors and how to solve them here.
