Example:
<a href="https://event-more-dangerous-website.com" target="_blank" rel="noopener"/>In a nutshell:
- Don't use the
relattribute on internal links. - Always use
rel="noopener"on external links to protect from Tabnapping. - Use
rel="noreferrer"on all external links except when you wish to get the attention of the external website owner (e.g., you want a link sharing partnership with the website). - Use
rel="nofollow"on all external links except when you endorse the external links. When you endorse an external link, they get some of your SEO juice. That's only good for them. You gain nothing from this except maybe nurturing a future partnership with them. - Make sure to sanitize all user-generated content's links by adding to them
rel="ugc". To be totally safe, the recommendation is to userel="ugc noopener noreferrer nofollow" - To mark content as sponsored, use
rel="sponsored". It is equivalent torel="nofollow"but adds more context. To be totally safe, the recommendation is to userel="sponsored noopener nofollow"
Yes and no. The Google bot follows the most contraining rule. For example, with
<meta name="robots" content="nofollow">The Google bot will not follow any links in that page, even if some are configured to be followed. However, with:
<meta name="robots" content="follow">Links configured with the rel="nofollow" are not followed while those without are followed.
No, but inconsistencies will make it hard to reason about your website. Use one or the other, or make sure that they are aligned.
