Another SEO professional was concerned about using quotes, linking, and guest posts.
When they curate content, they’re basically taking content from WebMD and using the snippet as a point of reference.
The SEO professional asked whether they should be providing a link back to WebMD as the citation of the source of information or not.
John Mueller said that if they’re quoting something, then including a link to the source of the information will always make sense. It’s really just a usability issue. Regarding SEO, there wouldn’t necessarily be a change just by linking to someone else’s websites.
John likened it to being a spammy technique like one that was used where an SEO professional would create a low-quality page. Then, at the bottom, they would link to CNN, Google or Wikipedia, and then they would hope that Google sees it as a good page just because it links to CNN.
Don’t over-worry about using good anchor text. Instead, worry about using good anchor text and link to your content so users are certain about what that content that is being linked to is as well.
Make sure you also include context in order to increase the user’s understanding of where the internal link links to.
The SEO professional had another question about guest posts. More specifically: how does Google know whether or not the guest post is paid and whether to burn the link or assign it value?
John said that guest post links should always be nofollowed.
Essentially, a guest post is an ad for your business. In that regard, John recommended making sure guest posts are nofollowed.
The link anchor text is really the part that makes guest posts problematic.
