Domain authority is an important ranking phenomenon in Google. Nobody knows exactly how Google calculates, ranks and rates the popularity, reputation, intent or trust of a website, outside of Google, but when I write about domain authority I am generally thinking of sites that are popular, reputable and trusted – all of which can be faked, of course.
While the title tag is effectively your search listing’s headline, the meta description (another meta HTML element that can be updated in your site’s code, but isn’t seen on your actual page) is effectively your site’s additional ad copy. Google takes some liberties with what they display in search results, so your meta description may not always show, but if you have a compelling description of your page that would make folks searching likely to click, you can greatly increase traffic. (Remember: showing up in search results is just the first step! You still need to get searchers to come to your site, and then actually take the action you want.)
Baseline ranking assessment. You need to understand where you are now in order to accurately assess your future rankings. Keep a simple Excel sheet to start the process. Check weekly to begin. As you get more comfortable, check every 30 to 45 days. You should see improvements in website traffic, a key indicator of progress for your keywords. Some optimizers will say that rankings are dead. Yes, traffic and conversions are more important, but we use rankings as an indicator.
