What are the best types of link exchanges that Google Likes? I have about 20 small websites and they are all interlinked (links of the rest of my websites on each website). 2 of them used to be pr4, and 3 or 4 others pr 3. Now they are all PR2. I think it is because of that interlinking. Anyway, what is the best way of linking in my situation? I know one way links are the best, but I don't want to leave any websites out. and who doesn't want those extra links?
one way links are the best way to increase, back links, as with link exchange you need relevant link partner, and by doing so, your business may be diverted. Forget about it. IMO.
As compare to link exchange, three way link exchange is better option else one-way is safe and better option to increase ranking. I also do link exchange but with high PR having very less links on the pages and the pages does not look like link farm.
Still One way link is the best way but you can also go for three way link exchange but don't forget the link should be relevant.
The best way of linking stes is one way link.... reciprocal also good, and better to avoid the 3 way link exchange
Google doesnt like link exchanges !!! Google wants natural linking! Google want organic linking, example: you write a great article and somebody else, who like what you wrote, is linking back to your article. The best link is one way link but that link is good to be inside another article surrounded with text wich has your keywords that are relevant to the site it is linked.
Don't just interlink all your sites. That's not good and it's easy for Google to detect such a behavior. Contact other webmasters and offer them links on some of your sites for exchange of links on their sites.
If you have one hosting for all domains, then it means same IP for all your sites. Linking between them will not bring good results. I suggest you try to get one way links from other sites.
