If you’re regularly working to improve your on-page SEO, you’ll not only want to look at the titles and description meta tags for your own pages – you’ll want to investigate competitors too. Digging around in the source code isn’t very efficient, so I’d recommend the free MozBar from moz.com. Although we use the subscribers’ version, there’s a version available for free Moz Community members.
Once you have the toolbar in place, it’s a single click in the top corner of a web page to see the various tags and alt text. You might be surprised at the ideas you can get from competitive pages. Give it a try.
