What is it worth to you to be number 1 in the search results for your keyword. AOL does a yearly release as to the click rates for the top 10 spots on the first page of search results.

Here is the way it breaks down for last year.

For Positions ranking from 1 - 10, the % of clicks for:

Rank 1: 42%
Rank 2: 12%
Rank 3: 9%
Rank4: 6%
Rank5: 5%
Rank6: 4%
Rank7: 3%
Rank 8: 3%
Rank 9: 3%
Rank 10: 3%

Yes i know it does not add up to 100% that is because i rounded the numbers and the rest of the clicks go to the lower level pages.

Now look at your visits per day for you keyword and figure out what your current percentage is and then what it could be by being number 1.
