According to a research brief from the Center for Media Research, people searching on the Internet will modify and re-word their searches until they get what they really want. It basically breaks down like this: 89% modify their searches if the first go-round doesn't produce the results they had in mind, 79% will leave the search engine all together and try elsewhere, and about 50% will click on a result if it has a picture or the brand appears multiple times on the results page.
As no surprise, Google comes in as primary engine for 75% of users. Additionally, it seems people first embarking on the road of search choose to use Yahoo.
Some more highlights:
-1 of every 5 users is more likely to click a sponsored advertisement
-Google users are more faithful to their engine than users of Yahoo and Bing
-More than 75% of searchers use it to learn more about a product after seeing it first somewhere else
