The quality of SEO services is depend on 2 important points: Keyword popularity and keyword competitiveness.
if your website stay in top 10 position for keyword that NOBODY searhes and NO COMPETITORS.. it's useless.
more popular and more high competitors keywords you stay on top 10, more quality of SEO services.
talking is cheap.. here one of my portfolio:
[login to view URL] is a furniture manufacturer from Indonesia. their main business is selling office furniture and hospitality furniture.
my june 2004 google report:
office furniture - #10 out from +4000.000 competitors
Furniture manufacturer - #3 out from +3000.000 competitors
hospitality furniture - #1&2 out from 561.000 competitors

executive chair - #3 out from +5000.000 competitors
modern office furniture - #1 out from +1200.000 competitors
furniture indonesia - #1 out from +700.000 competitors
and tens of other keywords such as: institutional furniture, kindergarten furniture, banquet chair, multi function table.. etc.
the power of natural SEO is your website stay on top 10 for long long time after the contract closed. not only homepage get ranking, also tens of internal page visible on top 30.. even top 10.
google dance.. florida syndrome.. etc.. will not affected to the natural SEO because it use LEGAL technique base on google guidelines.
the only weakness is natural SEO take more times.. no less than 6 months.
but 6 months for years placements.
