Some website owners or marketers will purchase backlinks to help drive traffic to their site. The more links that are out on the web leading people back to your site, the more traffic you could potentially receive.
Years ago people would trade links, placing someone else’s link on their site if the other person would put the first person’s link on the other site. That way both people got backlinks without buying them and both could get more traffic. The problem with that now is that Google does not give higher ranking to sites that merely trade links.
Since backlinks also help websites get ranked higher in search engine results, marketers quit trading backlinks and started to buy backlinks. This way Google will see the links coming back to your site and give you a higher score toward a higher page ranking in results when people search for your keyword phrase.
Backlinks can be posted for free on the web in many ways such as article directories, social media sites, and in free classified advertisement websites. However this process takes time and time is one of the resources that marketers want to reserve for more complex work. So they often pay people to post the link for them on these free sites. You could say this is another way to purchase backlinks. Of course the most obvious way to buy backlinks is by paying for ads on websites. But if you are paying someone to post your link you might as well consider that buying link building services.
The site the backlink is located on has a page rank of its own. The higher ranked sites with links to your site gives you more credit in Google’s algorithm than a weaker/lower page rank site linking back to your site. So the key is to pick expert or high page rank sites to post your backlinks on when you purchase backlinks.
Not only do a large number of backlinks help a website get a higher page rank in search engines but more traffic can come to your site with more backlinks available on multiple websites. Again you want to be selective about which sites you place your backlink on. If you buy backlinks you also want the site to have readers who would want to buy your product and will want to click on your ad/backlink. If the audience who reads that site is not interested in your products then you are wasting your money on those backlinks.
Make sure that backlinks are not placed in large numbers in one day upn lots of sites. Gogle only likes backlinks that gradually appear, a few each day, instead of dozens or hundreds in one day. So if you pay someone to post them make sure you specify the number per day you want posted. This will make the linking look natural and not as if youchose to buy backlinks.
Backlinking will get you higher page rank in search engines and more traffic to your site but quality content on the site is what will turn the traffic into conversion/sales.
