It’s always advisable not to give our free links to other blogs in WordPress and the best way to do about this is to nofollow all external links. When you nofollow an external link, bots will ignore it and it won’t have any impact on the web page it’s pointing to but when you dofollow an external link, it will improve the ranking on the web page it’s pointing to.
In Google’s perspective, making external links nofollow simply means you don’t trust the site the link is pointing to. There has also been a debate about Google rewarding sites that dofollow links and no clear answer has been got up to now from Google. Let’s assume Google rewards websites that dofollow external links, the point behind this could be showing that the web page the link is pointing to is superior than your web page.
From my own point of view and experience, i recommend you nofollow external links that only link to bad websites. You can keep the ones that link to quality websites. This has been proven to improve SEO structure to some extent because linking to bad sites will impact on your SEO negatively where as linking to quality sites will have a positive impact on your SEO.
How to Nofollow external links
It’s a burden to go post by post adding the nofollow attribute on every link. Sometimes it might be hard to find all external links on a website. Imagine your blog has over 5000 articles, are you going to edit each and every post to check for external links that lack a nofollow attribute? This is where a plugin comes in. In this article i show you the simplest way of adding nofollow to all external links using a plugin.
Step 1 – Download and Activate the External Links Plugin
Step – Configure the Plugin by opening it’s configuration settings page (In your dashboard hover on Settings >> external links)
Usually i recommend configuring the plugin the same way as you see on the screenshot above. Keep the first box unchecked that’s if you trust your theme doesn’t contain any hidden outbound links. The most vital box is the ‘Add No Follow’ box. This box should be checked to nofollow all outbound links on your website.
The settings page has so many configurations you can play around with. Just check the boxes you believe will give you the best satisfaction.
