Let us look at why SEO will never die.
SEO, an acronym for search engine optimization, is broadly defined as including any activity or set of activities designed to get business from the organic or natural search results in a search engine. If you change the title tag on your homepage in the hope it will cause your website to rank better on Google, you’re doing SEO.
There are ways to get business from search engines that are not generally defined as having anything to do with SEO. Adspace on Google is not part of SEO, but can be beneficial to your SEO efforts.
SEO will only ever die when Search Engines do. Until then, it continues to change and shape it's way around the Search Engines. The key is to stay on trend with the latest developments, and adapt your efforts effectively. So by definition even the word Search Engine Optimization (SEO) means to “game” the Google search engines (and others) to get your valuable content ranked higher than it would be if left alone to the forces of the Web. At the moment, Content is King. Google wants great, shareable content that people care about.
So, how does Google's changes affect your SEO efforts?
