Already Near Top of Search Engines

Gentlemen,

Great site here.

Is there any real benefit to using your product if a site is already at the top (or close) in all the major search engines?

My place is an inch wide, but a mile deep. In other words, it dominates its "space", even though the "space" is only about an inch wide (Second Generation Chevy Camaro Community). The obvious keywords (e.g. "camaro", "1970 Camaro", etc.) already show my place at or near the top.

Thanks.

I think you could still benefit if not all of your content is fully indexed. If every thread is showing up at the top of the rankings, then you're about as good as you can get now.

But, if there are threads that google isn't picking up, having them properly indexed and ranks will just give you that many more opportunities to lure guests in.
