Well because no one really knows the internal workings at Google, you're going to be waiting a long time!
Selling links is a big no-no! I have no idea how you managed to get PR7 being that ignorant about the state of the world... Google went on a massive offensive against link-selling a long time ago. I second this, apparently it works some of the time. The only real way to make money from PR7 sites these days is to SELL THEM. I mean sell the entire site, the domain and everything.
Somethings you need to know. - Its only a toolbar drop, its so you would stop selling pagerank. - It should not effect your rankings. I personally think that it be a waste of time if you complained about it. Unless you see like pagerank as something that is honorable? idk but if you just wasted 1 hour or so, you instead could of gotten more backlinks.
If you change the design of your homepage,I mean make it ugly by adding links,google may drop the pr.
what is a sitewide link? How does google know the difference between a paid link and a simple link swap?
A site wide link is a link that shows up in every page (IE in the footer). If it was a link swap, the other site would have a link to your site!
i think this is right, not sure 100% but if u place link to improve ur traffice and let people visit ur site clicking ur ads, then it makes good by google. but u pay for your ads for only backline despite of ur site providing pointless content then related(who pays for adding link to other site) may be banned by google. when u add nofollow in ur url u may not crawled by google consequently u wont be banned
How I see, you're one of the victim of PR dropping happened on the last update? How many backlinks does your site has?do they have good PR? Maybe you link to spam site or google caught you selling links!
I think you want to get some suggestions from others about text link adds. that's why you imagine a story like this. when was your PR dropped.? Its not updated yet....
Because they don't like competition. BTW: They allow you to sell links but not PageRank include in links rel="nofollow" so you will be OK
