It is the one question millions of publishers are constantly asking: what combination for my Google Adsense adverts will make me the most amount of money? The problem with the articles on the internet that claim to know the answer is that the answer varies for each and every website. For example, a website based around social media will have different results for a website evolving around books. For this reason, there is never a definite right answer to the advert combination that will make you the most amount of money. However, from the research of myself and other publishers, there are some ad combinations which will, if you get stuck, help you move into the direction of gaining the highest CTR for your adverts.
Google Adsense adverts include factors which affects how many times the advert gets clicked:

• Size
• Ad type
• Positioning
• Colour

Getting the right combination of the above will sure enough encourage clicks to the advert. This article is also going to be a two parter. The first part will look into the the ad size and type while the second parter will look at the positioning and colour of adverts.
 

Size

The typical size of adverts, much like fashion, change over the years. In the early days of Adsense, the longer vertical adverts were the most successful which is why many people used them. However, the ‘in’ advert at the moment are the squarer adverts such as the 300×250, 336×280 and 250×250 adverts. As well as having a lot of advertising space, these adverts are a better fit at the top and bottom of content which is why they are used. On the size basis, the bigger the advert, the higher the CTR. However, too many big adverts on your page will annoy your visitors decreasing your CTR. Learn the balance on your website.
 
Above I have basically described what adverts will earn you the most separately. However, many publishers, like me, use the maximum amount allowed of adverts on a website. Google have made this maximum at 3 adverts per page. This why you don’t want to have three huge adverts on your website. It will make your website look cheap and desperate for clicks turning visitors away from your site. From this, you should aim to have the following:

• A big advert – This can be considered 336×280, 160×600 or the 728×90 advert sizes.
• A medium advert – These are of sizes 300×250, 250×250, 120×600 and 468×60. Optionally, you can pick another 336×280 as a medium advert. If you do, try and place the two adverts as far away from each other as possible.
• A small advert – These are all the remaining sizes which fit one or two adverts. This also includes all text link adverts Google offer.

Ad Type

This has always been a dilemma for both publishers and advertisers. Choosing whether to use text adverts or image adverts has always been a tricky decision because both types of adverts have benefits and negatives. With my website, Ask Will Online, I have found that:

• Text adverts have a CTR of 0.34% and CPC of £0.35.
• Image adverts have a CTR of 0.36% and a CPC of £0.19.
• Flash adverts have a CTR of 0.16% and a CPC of £0.49.
• Rich media adverts have a CTR of 0.18% and a CPC of £0.92.
• Animated image adverts have a CTR of 0.25% and a CPC of £0.18.
• Video adverts have a CTR of 12.27% and a CPC of £0.03.
