This is my list of the best SEO bookmarklets to use. My focus is on technical SEO, so this list will most likely contain many SEO bookmarklets which fall into the technical topic.
To use any of the bookmarklets, simply drag the title of the bookmarklet into your browser’s bookmarks.
My own bookmarklets
The following bookmarklets are my own creation. Use them if you like. They might not be super helpful for you, but they are helpful to me (at least).
The bookmarklet will let you identify images on the currently opened page which are not rendered in their original dimensions. This might help you identify images which are, for instance, displayed smaller than they originally are, so you can work with that list to reduce image file size and page load time.
The bookmarklet will
- Display a red dashed border around all improperly sized images on the page
- console.log an array of found images
- download a CSV file with all improperly sized images in it. The first line of the file is the title line.
The fields in the CSV are: image src attribute, actual width, actual height, rendered width, rendered height
This bookmarklet highlights all headings <h1> to <h6> on the current page in different colors. Open the dev-tools / browser console to get an array of the headings, grouped ny heading type.
