Google, the most widely used search engine its search algorithms modified in an attempt to reduce the amount of spam content in search results. With this in mind, it pays to remember that it is in the interests of both you and the search engine companies to produce content that doesn’t have the typical spam features, such as keyword stuffing. The aim of Google is to produce results that are pleasing to people searching out websites, so having a high quality site can act as a form of SEO in itself. In the long run it’ll pay off as more specifically optimised pages eventually become obsolete Producing consistent content is all very well, however it never hurts to use SEO to gain an edge over competitors and also for effective SEO.
Overall, the future of SEO will be more complex than in the past. Old school techniques to fool search engines continue to be weeded out, but if you construct your content with longevity in mind, and are diligent with implementing emerging social networking features, you can ensure that your sites are future proof.
