Not always complete and perfect, but it's a great starting point for thinking about keywords that would be effective in your space.
Figured one way to differentiate ourselves was strict honesty.
Sure enough, after over 2 years, i only had to delete 2 records from the database for obvious abuse and the comments are about 90% favorable and maybe 30% positive raves like you could never make up yourself. Yet visitors can see the negative comments, so they can believe in the positive ones.
Most sites that use "testimonials", show a few selected ones that read like ad copy and sound like one voice.
Just added a test ad that mentions customer feedback in the title and lands visitors on that feedback page, rather than the home page. Will be interesting to see the results.
There are times when the best person to mine for keywords is the competitors top affilates.
There are many times when the affiliate sites are much better optimized than the actual merchant site, and doing some link checking to find the top affiliates who have done extensive research into keyword areas can save you a lot of time, especially when you find one that has at the bottom of the page: 'Relevant Keywords' and a list of 500+ words.
The client i mentioned above is in a small niche market where i don't think our competitors have many affiliates - but i'm going to check again.
Certainly i can look at our own reseller's web sites to see if any have come up with useful key phrases.
And thanks for this thread, Blaze.
