If your company does search engine optimization then you should be using Google Analytics. Now, this post is not a push or plug for Google but rather helpful advice for how you can understand if your SEO is working, how well, and what you can do to make it better.
When you use the analytics, you can see how many people visited your site for a specific period of time , how long they visited for, how many pages they viewed, how many got to your site through organic means or through directly putting your URL into their web browser. These are great tools to see how how well your SEO is working.
However, another great reason to actually analyze your efforts is to see how people are getting to your website. Are they getting to your site through the keywords that you have been using? If so, which ones? These are questions that get answered if you use Analytics.
Are people getting to your site via computer or are they looking at it through a mobile device like a smartphone or tablet? If they are using mobile devices more, then your site will have to be mobile-responsive so mobile users are able to view your site effectively; otherwise, they may scoot away from your site quickly, raising your bounce rate.
Are people in the area your targeting with your SEO looking at your site? You can find that out with a look at your analytics.
The bottom line is that if you are going to do search engine optimization, then it would be foolish to not monitor that and see how things are working out. Blindly hoping the efforts are paying off could be a waste of time and money.
