There was a time when seo gurus defined in-content backlinks as most powerful tool on the basis of their experience. Article directories were introduced and writers came on to scene to write bundles of articles each day and posting them on large no of article directories. Some of these article directories proved really good in terms of results but others were just waste of time. Keeping this in mind webmasters became selective in selection of directories and made certain criteria to submit articles only on quality article directories.

This procedure went on for a long time when search engines came on to the scene to describe duplicate content as a bad thing for seo. Here started the new war of backlinks as writing different article for each article directory cost them huge money for writers. Article spinning proved to be a good alternative for writers but it was not so good to produce convincing results. This also increased the cost of seo services for top seo companies. Each and every seo company running through the problem of duplicate content had to think a solution and they finally sorted out in the form of blog posting.

Some of the seo companies and even webmasters made cluster of helping blogs to their targeted site and started to produce in content quality backlinks on daily basis. On the other hand they did promotion for their blogs so their backlinks should come from more powerful pages. This method proved successful until search engine like Google described these links from same person’s websites so they decided not to give any importance to these links. Here came the role of seo hosting with which webmasters were able to host their website on multiple c class IPs. This is too costly to afford for most of the webmasters. To solve this issue many cheap seo hosting companies are coming into the field to make things simple and easier.

In the end I must say struggle to grab top ranking on search engines is on and with the passage of time rules by search engines will become harder and harder. At the same time seasoned seo specialist will keep their efforts coming to ease seo rather than saying, “seo is dying!”
