NoFollow Chrome extension is another useful tool especially if you plan to do guest posting for link building. With the help of this tool, you will be able to identify websites that accept guest posts but their outbound links are nofollow.

There’s no need to have your guest post in such a blog if your intention was to get a backlink that would boost your SEO metrics by passing link juice to your blog.

Nofollow links contain metatag that tells Google not to follow the link; hence no link juice will be passed over to the target page.

After installing the extension, visit a blog or website that allows guest posts. The extension will put a dotted box around nofollow links.

Therefore, if you notice most of the outgoing links to other sites are nofollow, then it probably might not be worth your effort if you’re after backlinks that will pass link juice to your blog.

15. Page Load Time

Does website speed qualify as a Google ranking factor? Yes, it does, and Google has already made it public that they use page speed as one of their ranking factors.

Faster websites are more user-friendly and will rank higher provided they have quality content and have a user-friendly design.

Page Load Time extension measures the loading time of a webpage and displays the metrics in the toolbar. If the page speed is low, you can see what’s causing the issue.

It can be too many redirects or many requests or server response time among other things. You can then use the data to guide you on what issues need resolving.
