I don't know. My signature link is now on the same page as makemoneyfreemoney.com. A site that probably so spammy I wouldn't click on it with your mouse (no offense). It's probably harmful if anything in terms of SEO. However, direct traffic is valuable too.
Everyone is saying they are good. I'm saying there not bad or hurting your website so they must be good then. Unless they are spammed some how.
dofollow links are helpful to build more links, but i do not think there are helpful for ranking your site. And relevancy is important. anyway get exposure is good for your site.
When you choose relevancy, you should choose thinking like a dum spider bot. If you have a travel web site, your relevant dofollow should be about travel. I believe that is correct but how does google knows that one is travel and another is something else. Dmoz? Keyword from metatags, text, link from other?. So if you post on Avion Travel fans blog, would that be helpful just as much as a real travel blog?. Also, does google takes into consideration if linking site to the blog/forum are about travel (just to continue my example). Best would be to use the keyword you want to gain position and than add blog or forum and dofollow. Maybe you can find a good one.
Signature links are more powerful and u can get quick listing in google, my opinion is it is good as to have many backlinks which includes signatures, but i am not sure that having backlinks in pro or n/a will decrease your site PR. But to get quicker listing in Se and get easily crawled by se spiders, you must be having some backlinks which are exposed to many people, that can be done through signatures, i think.
Sig links will not hurt for sure Besides, they are useful for your site indexing and can contribute to your page rank in the long run
if not why this forum is so popular? only because of content? signature link is helpful and there is no doubt on it. but yes only this method then no.. u must have mix of all kind of links..
I think Google doesn't give much importance to them for SEO purpose. but it can bring you lots of free targeted traffic Thank you
Honestly I am not sure if signature links help with PR or not but I think it does...even a little. Signature also helps a little in traffic I guess.
I guess the concept of signature link is not that much popular now as it was couple of years back. It does count now, but maybe out of 10 hardly .8% (not sure). Its all because google changes their algorithm.... The way they look at the link which is pointing out to a particular site depends on their own structure.
What I see happening in small sites is that the site builder makes the regular links but indicates to the owner a couple of good dofollow forums to post good real authentic posts. this way the owner participates to the link hunt and gives a costant flow of singature links. What happens is that this 3/4 weekly posts are important to keep site position. We are not just fighting to get first page, but also not to sink down. I have seen competitors sites on first page going back so rapidly because they have stopped linking. Mostly because they stopped using their seo and thought "now that I am in first page who can send me back?".
I believe articles are going to be soon downgraded. Google is at serious risk. All the internet is loaded with articles that are of no interest, duplicated, badly translated, made up for the link campaign. This downgrade the whole internet as a source of information. Right now it is easy that if you are looking for something that you catch these articles instead of the real information.
