There is so much literature on the Internet via forums and blogs about link building, yet if a person decided to read all of it 2 things would happen:
I must give credit where credit is due, Alan Page and Sergey Brin of Google (mostly Alan Page) developed a whole linking structure that Alan named after himself called "PageRank." The algorithm is actually quite long and complicated, but in essence Pagerank measures the number of links pointing to your site from other websites. The more links you have pointing to your site from established websites, the better your rankings tend to be.
Over the years a whole cottage industry of link builders grew off the invention of a couple of guys from Stanford University. Then the industry took a strange turn and started "exchanging" links. This is where you put a bunch of links on your site, and a bunch of other people place the same links on their site and everyone in the circle points back to everyone else in the circle. This methodology of link building worked for quite a number of years, until the engineers working for the search engines decided to discount or disregard link exchanged websites. In some cases, sites that were doing link exchanges lost so much rankings that they were not able to be found in the first 999 results of Google and Yahoo.
Then came the text link buying craze where people were out shopping for PR (pagerank) 4 or more having sites to buy links from them. A whole other cottage industry was spawned and people were spending as much as $3000 per site per month for pagerank 9 having sites. Unfortunately, that too began its slow demise in late 2007 where the search engines started devaluing sites that were selling and/or buying links.
So, what are companies to do when they want to get to the top of the search results on search engines like Google with their most difficult to rank keywords. There are still many many ways. The Internet is built on links and they will always be around in one shape or another. The key is knowing which shape counts as a link that will increase your rankings and which shape will not.
I offer 3 different tiers of link building services. At the highest tier, I can guarantee top 5 rankings in Google for your most competitive keywords (even 1 word keyword). However, this is defiantly a costly proposition and is for companies that are spending $80,000/month and up on their keywords expenditure with search engines. I can save such companies tens of thousands of dollars per month. If your company is in a situation like that, I can get your site to the first page top 5 rankings of Google even for your most costly and competitive keywords for a fraction of the cost. My fees are listed below. Let me know if I can be of any assistance to you.
Please note, I can only take on a very limited number of clients for this service. In addition your website must be up and running for at least one year.
