Tip 1
Get backlinks from Forums. But you have to look out for no-follow tags. If the link has got nofollow tags, it means the website is not passing backlink to your website.
Tips 2
Use link exchanges to speed up the link building process. You can use Linkalizer, Simply Linking or Link Market for that process. Of course, the important factor would be the number of members the link exchange has.
Tips 3
Requesting link exchanges from webmasters. This is tedious but you can be selective in searching the links you want to get. It is always good to get links from competitors or high profile websites.
Tip 4
Search for websites that are willing to do link exchange by keying in addurl in Google. You will see a whole list of websites. Most of them have an automated link submission script installed.
Tips 5
After linking, you need to constantly check whether the link exchange partners still have your link on their website. To check this, you can use a SEO software to do that.
