Hope these tips will help you to avoid problems in your link-building business!
1) Always check HTML code of the page!
Some link sellers put your links on a page and everything looks pretty good, except… that these links are not working! Visually everything looks nice, but when you make a simple magic action: Ctrl + U you can see all the background. To check it, press Ctrl+U, then Ctrl+F and there will appear a pop-up window (in Chrome – upper right corner, Mozilla – lower left corner). Type there the name of your link, e.g.: site-example.com and press Enter. If you won’t find your link in the code but you see it on the page, be sure that it is closed with Java Script. In this case in code you will see something like this:
If you can’t find your link in code, Google bot won’t find it too!
2) Always check the seller’s reputation. For this you may find additional information in Google. all you have to do is to enter following queries into the text line:
3) Check the quality and quantity of backlinks to the site you buy link at. For this you can go to Yahoo and enter “linkdomain:donor.site.com“. There you will see the list of domains that have links to the donor site. Be very careful! There should not be sites with adult content! It is pretty good if you find there trustful sites, like en.wikipedia.org, or .edu, .gov sites.
4) Calculate the PR of the donor’s domain. If you want to buy a link from the site with PR 5 (for example), check it’s backlinks. Site with PR 5 can’t have only 40 links from original domains! There should be around 400 links from original domains for PR 5.
How to calculate PR? PR / quantity of backlinks with ORIGINAL domains = PR ratio from 1 site. It can’t be more then 0,06. Usually you get 0,02 PR ratio from 1 site. For example, in our case PR 5/ 400 = 0.0125. According to our calculation, you can be more or less sure that the PR 5 is not a fake one if there at least 250 backlinks from original domains (PR 5/ 0.02 = 250).
