I am talking with someone who offer me to give a PR8 link and i will give him a footer place sitewide on my PR6 site. Normally i think this is a great offer, i should accept this. But since i am not experienced in SEO i dont know what to do because of some possible problems. Let me know what you think. Should i echange the link? Here are some of the facts related ot exchange and site: 1. The site is 10 years old and i think this is why that site is PR8. Because seomoz pagestrength of the site is 5.5 and mine is 6. 2. I have ~8000 pages indexed, the other side do not have more than 200 pages and all has PR0 except the homepage. 3. My site is my main site and i dont want to risk it in any way! 4. My link on the other site will be static but his link on my side will be generated by a php script. With the help of that script he will change the url o the link at ever reload! In fact this is the main problem, what will google think in this case? Can google give me a penalty for this? Another problem with his dynamically generated urls is that they look too spammy. They look sth like this: mysweethotel.com/AdiR/anotherDir/travel.html In there "Adir" and "anotherDir" are meaningless and looks like case of the letters are generated randomly. And these pages are PR0 and i dont see any real use case of them! Is this a black hat method... ? What are advatages of having such randomly generated deep urls on high PRed sites? Do you exchange link in this situation? Thanks.
