I have been noticing more and more provider sites that when you click on the site the first thing you see is an ad. You have to close it to get to there site and saw one that had pop ups and smaller ads off to the side. I do not know about anyone else but those type of ads are a pain in the ass! and very annoying.

Some "free" escort web site builders are set up that way n the only way to get rid of the ads is to pay for premium.

Thank You Jamie I did not know that

and have to get sponsors I guess. I have my own site (new one coming soon) and prefer the cost over not seeing all those ads on my site.

I prefer having my ads posted over the website. The only reason I created my website is for the TER, so I would be able to post my ads here when I need it, of coarse it's free. I have not seen any pop-ups when I look at my site..  
If you notice, websites often contain one information (e. g. prices) and ads have different/updated, same with the pictures. I'm not saying all ladies, but many. Almost all websites contain professional/airbrushed pictures. In ads, most of us--indies--post the most current self-shots, therefore more realistic. If I was a shopping-around client, I would look for the ladies' ads (e. g. p411, rs2k, on ter, even eros) rather than personal websites, but that's just me.
