Publishers can use Adsense for Search to offer a search tool on their website. The search tool delivers results that contain Google Adwords adverts so that publishers can earn money.
The functionality of this tool for website visitors is what makes it so effective for publishers. Those who have searched a website's resources can return to Google to complete their search. If that resource is on a website they are currently visiting, they are more likely to perform a search on the publisher's website, resulting in revenue for the publisher.
Publishers often claim that including a search function on their website is a great way to increase Adsense revenue without jeopardising their brand. Just as a company selling a product would not want a competitor's Adsense advert on their website, they will not see this disadvantage as significant. The advantages of AdSense for search are also based on the space it takes up on the screen. Because the results are displayed on a separate page, publishers do not feel that they are losing space where Adsense used to be.
In addition, visitors may choose the specified website as their homepage when using the tool. If a website offers useful resources and still has Google-related features, it is attractive to a wider audience. Those who visit the site for the first time and find that it does not meet their needs can still use the search tool.
Adsense publishers often claim that they earn less per click with Search than with Adsense. Nevertheless, surfers are more likely to respond to adverts than with Google Adsense. If a visitor changes their mind about what they want to search for and is not influenced by the adverts, they may still find it as the publisher receives a percentage.
It is also a useful tool because it allows publishers to have their websites searched using the same technique. This makes it more likely that searchers will find the material they are looking for on the publisher's website.
As advertisers are more selective, Google has a smaller pool of Adsense adverts. Advertisers who do not want to appear in Adsense for content will be included in the search bar results.
Large market-leading websites use Google for search, which is unusual for Adsense. Companies that offer a service or sell a product are more likely to include the search bar on their website, even if they believe it devalues their brand.
Many companies even find that aligning their logo with the Google logo strengthens their brand. Others that don't use the Google logo can benefit from giving customers the impression that the search technology they are using belongs to the website they are on, allowing the publisher to reap additional benefits.
Since click fraud is a problem with AdSense, it is less likely with search. Click fraud would require the perpetrator(s) to conduct a realistic search and avoid any suspicious behaviour. This could prove extremely difficult, and people who commit click fraud are likely to avoid search altogether due to the lower revenue per click.
