Analytics SEO tutorial on the Missing Alt Tags component.
As part of our weekly deep crawl, our spider will also identify any instance of a missing AltTag. The front UI will give some analysis of your site’s status in this respect and if you click on the Optimise button, we will show you all the missing alt tags the spider has found.
As you can see, we also preview the images in question. This enables you to quickly flick through this report and decided which images should be optimised. Simply delete the rest and then export the remaining table and send it to whomever has the responsibility to fix such issues.
