Version 0.3 Requires a Bookmarklet Re-Install
Starting with Version 0.3, you can click on the bookmarklet to quickly close the bookmarklet tool. To get it working, you’ll need to re-install your bookmarklets. Just remove your existing bookmarklets and use the new code from the Install section below.
Every day as an Internet Marketer I review web pages to see how their on-page optimizations stack up against best practices to find out where they might be improved. With all of the different factors that go into on-page optimizations, it can often be very cumbersome to search through the page source to find all the areas of optimization I regularly look for.
So I built a bookmarklet that highlights the areas I look for most often, as well as a bunch of external tools I use to check other aspects, such as the readability of the page or how old the domain name is.
How it works
The bookmarklet opens a window over the page you’re viewing to show you a bunch of different SEO factors and links to external sites. When you’re done just click the red "x" button at the top right and the window will close. You don’t have to leave the page or view the source.
There are two flavours, the stable version and a "Bleeding Edge" version that I might tweak from time to time (and may not work 100% all the time as I work on it). Drag the links below to your browser’s toolbar to install it, or copy the text in the textareas to create your bookmarks manually (useful for creating the bookmarklet on your iPad or tablet).
Stable Version (v. 0.3)
Drag this to your bookmarks bar: SEO

Drag this to your bookmarks bar: SEO (BE)
or copy this code:
Install on iDevice
On an iPhone, iPad, or iPod Touch you will have to create the SEO bookmarklet manually. The process is a little involved, but well worth it to be able to check out SEO factors on the go.
- Select and copy the code in the box (in the post above)
- Tap the ‘action’ icon in Safari (the one that looks like a box with an arrow in it)
- Choose ‘Add Bookmark’
- Change the title to ‘SEO’ and choose the folder you want to save it in
- Tap the ‘Save’ button
- Now go to your bookmarks and find the bookmark you just titled ‘SEO’
- Tap the ‘Edit’ button and tap the title of the bookmark
- Select the URL, clear it, and paste the code you copied into the URL input
- Tap the back button in the top left. Your changes should be saved.
