The Changing World of Search Engine Optimization
Search Engine Optimization (SEO) is not a static field. There is not a simple set of techniques that you can expect to maintain its effectiveness year after year. The activities that had huge results one year could fall victim to a search engine algorithm change and be fairly ineffectual the next. The important thing is to stay up-to-date with these changes and make sure that you are using the strategies and techniques that will be the most beneficial for your site.
In the beginning, all a search engine optimization firm had to do was tweak the meta data of a site to help it rank better. Then, as companies began to abuse this technique, the search engines changed, and now those components of a website have almost no value in a search engine. The problem was that meta data does not provide a lot of useful information for a real person, and in the end that is what a search engine wants to see – the real data that a real person can use.
Most search engine optimization services now focus on the balance between content that will appeal to real, human visitors, and content and code that will help the search engine spiders. As new forms of content deliver become available (social media outlets and other resources) these SEO firms will have to continue to change their offerings to take advantage of these new methodologies. In a year, social media might take a back seat to some other new tactic, and the best firms will be able to adapt their services to include it.
