People find their way to your website in many different ways. If someone is already familiar with your business and knows where to find your website, they might just navigate straight to your website by typing in your domain. If someone sees a link to a blog you wrote in their Facebook newsfeed, they might click the link and come to your website that way.
That's why it's necessary to always stay abreast of developments in the SEO world, so that you can see these algorithm updates coming or you can determine what to do once they’ve been released. The WordStream blog is a great resource for SEO updates, but we also recommend Search Engine Land and Search Engine Roundtable for news on updates. Glenn Gabe of G-Squared Interactive is also a great resource for analyzing the causes and impact of algorithm updates.
Remember when you used to rely solely on search engines for traffic? Remember when you worked on SEO and lived and died by your placement in Google? Were you #1? Assured success. Well, okay, maybe not assured. Success only came if the keywords were relevant to your site users, but it was the only real roadmap to generating site traffic and revenue.
