Is it true that outgoing links weak position of the site in google? If it does, why many directories administrators inform that when you put reciprocal link it makes your site easier to index. It seems to be contradiction.
Outgoing links don't hurt your position in google (unless these links are sell links or are linking to spam sites.)
What you're referring to is people who state that outgoing links weaken your PageRank. This is true, but PageRank doesn't always equate to high positions in the SERPs. My advice is to link back to any site you think is valuable to your visitors. The sites you link to are considered your neighborhood. Link back to good sites and the search engines will see you as being in a good neighborhood which will help your SERPs as much (and probably more) as losing the PR hurts.
Linking out to sites can effect your PR but this is not the end of the world aslong as the links are relevant for your visitors. This is more important keep the visitors you get happy than worrying to much about whether linking off will effect the site to much. PR is only part of good SEO; get some unique content, backward links and a keyword rich site and you will be well on the way.
OK thanks guys for your opinions, i don't afraid about mypagerank due to the fact that it's 0 so one good thing is that it can't be worse, anyway what about nofollow attribute and robots.thx, do they work and block googlebot to count these link or not?
