The search tool provides results which contain adwords adverts, and therefore publishers can generate revenues. The effectiveness of this tool for publishers comes in its functionality for website visitors. Those who have browsed resources on a website may return to Google to complete a search. If this resource is contained within a website they are currently on, then they are likely to use the publisher's website for search, and therefore the publisher can receive returns. Publishers often claim that having a search tool within their website is a good way to generate Adsense revenues without the concern of diminishing their brand. In the way that a company who sells a product would not want a rival provider having an adsense advert within their website, they will not feel that this disadvantage is relevant. The advantages of adsense for search also lies in the space that it occupies on screen. The results are displayed on a separate page, so publishers do not feel that they are sacrificing space where Adsense would previously appear. The tool may also lead to visitors selecting the given website as their homepage. If the website contains relevant resources, and still has the functionality associated with Google then the website has broader general appeal. Those who are visiting the website for the first time, and realising it will not satisfy their needs may still use the websites search function. Adsense publishers often state that they receive less per Click Through with Search. Although this is the case surfers are more likely to be targeted towards adverts than with Google Adsense. If a visitor has have changed the item or topic they wish to search for, and isn't compelled by the adverts; they can still find what they are looking for as the publisher earns a percentage. It is also a good tool as publishers can allow their site to be searched using the same technology. Therefore surfers are more likely to also find the resources within the publisher's website that they require. Google has a lesser database of advertisers for Adsense through the selectiveness of advertisers. The search toolbar provides results which include advertisers that do not want to appear in Adsense for content. Google for search is also used by large market leading websites where this is rare with adsense. Companies who provide a service or sell a product are more regularly opting to incorporate the search toolbar into their website whilst not feeling that it depreciates their brand. In fact; many businesses actually feel as though their brand is strengthened through it's alignment with the Google logo. Other's who choose not to use the Google logo, may benefit from the customers assumption that the search technology used belongs to the website they are on, and therefore further benefits are reaped by the publisher. As adsense is plagued with click fraud, the same is less likely to happen with search. Click Fraud would require the person or persons committing the crime to follow realistic searches, and to avoid any suspicious behaviour. This could be particularly hard, and with less revenue per click those committing click fraud are likely to stay away from search all together.
