In choosing where to get links, there are major factors to consider:
1. You have to look at the page rank of the website. Why?
Because the higher the PageRank is, the more Google juice you can get from it.
2. Look at the website’s niche. Is your site related to this website?
If you’re not related, the links you’re going to get from that site is next to useless.
3. Look at all the outbound links the site is giving away.
Too many outbound links can mean that you will be sharing with all the other websites that this site is linking out to – giving you less Google juice compared to sites with low outbound links.
4. Look at all the sites it gets its links from. Are they reputable sites?
Are they related to your niche? Maybe you can get links from those sites too.
5. Look at the site’s links if they are nofollow links.
If you're trying to rank (especially in Google), nofollow links will not help. So you better look for sites that don’t put nofollow in their links
There are many ways to get links. Some are effective in boosting your rank, some are effective in giving you traffic, and some are effective in wasting your time.
