Rel=nofollow sponsored ugc - what does it mean?
Google recently announced a couple of fairly important things in terms of the nofollow attribute.
For a long time links have either been a regular link that is followed by search engines (often incorrectly referred to as a dofollow link) or the link could have a rel=nofollow attribute applied that would tell search engines not to follow or consider that link.
And so this was for many years.
Google decided that they needed to be a little more granular and that not all nofollow links were not to be followed. Some publishers put blanket nofollow on many links even if they were produced on quality sites and linked to quality resources by authoritative experts.
Google introduced the rel=sponsored for indicating a link was a paid or sponsored link and the rel=ugc for user generated content.
Generally the reaction by the SEO industry has been fairly muted.
Google won't implement the full effect of this until march 2020.
This could be a fairly bug deal for sites that have a lot of nofollow links. If you have a large percentage of nofollow links, you should evaluate what the quality of those links is as this change may effect you.
