I have heard that signature links is a great way to start promoting a site and increase the rankings and have several questions: 1. How long does it take for the search engines to crawl the signature? 2. Is there a maximum # of signature links you should go after in a short period of time? I have heard of some sites being penalized for adding too many links too quick? Thanks
It depends how often the spiders/bot come across to crawl a forum. Nope that's not true. You can add how many you want.
A new site of mine was indexed within 2 days because of my sig link on DP only. It's really helpful, also to target a particular keyword.
It depends from forum to forum as for example a signature in DP here can be crawled within a few hours whereas a signature in a less crawled it may take some time There is no maximum # of signature links you build but it should look natural to google and not paid ones the same theory which goes for link building and also try to get a signature from your niche it helps immensly
it depends of the forums reputation in search engine and alexa ranking if you buy signature link in forums with alexa ranking<5000 usually it takes around 7-10 to be indexed in search engines. I've done this for some clients, and usually they prefer to buy 30 to 50 posts(links) from a forum, as usually not all links are being indexed. If you still have some questions, please feel free to pm me. I'd be happy to help/guide you.
Signature links are also useful to increase back links. Some times relevant back links depending on the content in the thread and the links used in signature. You may also index your new website in just 1-2 days through signature links.
signature links are veru useful, but how do i find high traffic forums? Now many forums don't permit signature.
