To quickly perform SEO work on your site, write JS code taking into account the actions below:

1.Duplicate content


This bookmarklet returns the results of a Google search to see if content is duplicated.

The code takes the current location (location.hostname) and combines it with the document title (document.title) to create a Google search query. The title is enclosed in inverted commas to ensure that the search engine is looking for the exact phrase. The escape() function is used to ensure that special characters such as spaces are correctly encoded. Finally, the replace() function is used to replace any remaining spaces with a plus sign (+).


javascript:void(location.href='http://' + + '/robots.txt')

This text file is located at the root of your site. It tells search engines where to index your site and is generally used to check whether a website has a robots.txt file and what it contains, although this information can usually be obtained more easily by simply adding /robots.txt to the end of the website URL in the browser address bar.



This code redirects the user to a cached version of the current page on Google. This is useful for pages that no longer exist or have been updated since they were last indexed by the search engine.

It allows you to know the date when the robots last visited your website.



This code will open a new window with a Google Mobile-Friendly test for the current page.

This code will open a new window in the browser that will direct the user to the Google Rich Results test page with the URL of the current page as a query.

This JavaScript code opens a new window with an overview of the links for the currently viewed domain.

One of the largest and best-known link databases is Majestic. By clicking on the bookmarklet, you open the current website in the tool. With this bookmarklet you can directly see the strongest links of any domain.

7.Canonical URL
