Have you ever just watched someone while they where doing a search?
Don't ask questions,or make suggestions,while they are searching.
Ask your questions afterwards.
Clearly marked paid listings don't bother me,and I often click on the top paid,and non-paid,listings.
And,yes,I do know how much it costs to run a search engine,but I'm not telling.
You would be surprised,at how much it costs,just to weed out the bait and switch sites.
Say you're looking for "Jill Whalen Exposed',and instead you get ... oh,sorry!

got carried away ... where was I? ... oh,yah ... meanwhile,back at the forum ...
The costs of developing new weapons to fight the enemy,can easily drain all but the deepest of pockets. ... guess who has been watching war stories on the History Channel?
All the surfer wants,is the information that they are looking for.
If it's a paid listing,it should be CLEARLY marked as a paid listing. ... that's my complaint.
I don't like to be tricked,and a lot of people that I've asked,feel the same way.Even when they find what they are looking for,they don't like to be tricked ... you lose peoples trust when you trick them.
