Analysis of External Links

External links connect other domains with links on your owned pages. Pay attention to using this function of an SEO check website extension. External links are even more important for rising the ranks in search engines to top positions as they show how many and which links go out from examined pages.

The Plerdy Chrome extension checks the number of ALT tags for each sample. It highlights images with missing attributes. As far as it allows adding a text description to the image, it can include keywords as other parts of the text. Algorithms of Google Chrome and other search engines also consider this parameter.

Plerdy allows analyzing whether pages suit the Open Graph standard. With it, you understand how users see page previews in search engines. A relevant page gathers more attention and ranks higher in Google. Algorithms check the following parameters:

  • og:title – object’s title that appears within the graph
  • og:description – similar to meta description, a short page explanation
  • og:url – a canonical object URL or its permanent ID
  • og:type – a necessary specification that defines the object type
  • og:image – an URL that presents objects within the graph
  • og:site_name – represents how your website is named
Automatic Information Collection

Do you have a large site with thousands of divided sections? You need to add some Plerdy extension tracking code before closing the body tag. After that, statistical information will be collected automatically. Paid packages of the Chrome extension store webpages’ data history from 30 days ago. Don't risk losing first positions on Google over silly mistakes!
