These bookmarklets can provide quick access to various SEO tools and insights directly from the current webpage, without the need for installing additional software or browser extensions. Below is list of my simple bookmarklets. You can use them too. But I recommend to install [Devaka Tools](https://devakatalk.com/devaka-tools/), panel with all needed bookmarklets in one place. To install a selected bookmarklet, drag and drop the link in heading below to your bookmarks panel. Also you can copy link (it will copy js code from the link href attribute) and paste it in your bookmark manually ([read more](https://devakatalk.com/installing-js-bookmarklets/)). ## 1\.
