Search marketers know that if the title of the ad matches the searchers keyword query, they stand a good chance of getting the click.
This mirroring strategy works for obvious reasons. The visitor already has a psychological attachment to the phrase - after all, they typed it in!
Making Sure You Get The Click
A lot of SEO strategy talks about how to achieve rankings.
Whilst important, the SEO pro knows ranking is only half the battle won. While it's true to say most searchers will click on the top results in preference to results lower down the page, they will also scan across the various titles displayed. All links on the results page compete for the click, and a compelling title may win out over a higher ranking position.
If the user doesn't find what they want when they scan, they will likely rephrase their search and try again. So the way you phrase your title tag is not only important in terms of helping attain a ranking position, it is also important that it stands out.
