SEO is Ever-Evolving
What it takes to get content to rank has been evolving since the creation of search engines. As search engines get better, what they look for in a piece of good content has changed. Some take this to mean that, eventually, they’ll get so good that we’ll no longer need SEO.
There are a number of reasons why these assumptions are off base. The most obvious is that the number of internet searches continues to skyrocket. More internet searches only mean SEO will become even more important.
Search engines will keep changing. However, they will always need to rank their results based on metrics. With that being the case, we will always need to optimize our websites for those metrics, no matter what they are.
