It's been 14 years! This week Google adds two new link attributes in addition to the nofollow link attribute introduced in 2005.

1. Sept SEO Updates #2
SEOPressor Official

2. Google adds two new link attributes - “sponsored” & “ugc”

3. … but why is Google making these changes?
Or more specifically, what most don’t understand is what
kind of incentive there is to site owners making these
changes.
Because Google has also said that it is perfectly fine to
leave your nofollowed links as they are and just ignore the
rel=ugc and rel=sponsored options.

4. In most cases, nothing has changed.
So what does this mean? Some SEOs think that the important part of
this whole announcement is that Google is treating rel=”nofollow” as a
hint now, and not a directive.

5. Google has Updated the Quality Raters Guidelines!
1. Huge Emphasis on Original Content: Important for News Sites and Informational Sites
In several places, the QRG have changed to emphasize the importance of having original content.
This correlates with one of Amit Singhal’s 23 questions on Google Webmaster that concerns a site’s quality, which is:
Does the article provide original content or information, original reporting, original research or original analysis?

2. Google Sees Use of Original Images and Videos a Sign of Higher Quality
In the “Very High Quality Main Content” section, it reads:
This seems that Google will most likely start applying E-A-T (Expertise , Authority, and Trustworthiness) filters to image
search for YMYL queries.

7. * Google search shows trusted websites like healthline and
webmd while the same query on image search shows more
alternative health websites

3. Clarification on what YMYL (Your Money Your Life) means
Google also made a few clarifications on YMYL pages, describing them as “type of pages or topics that could potentially
impact a person’s future happiness, health, financial stability or safety.”
There’s also differences in terms of YMYL examples and one important info for shopping/ transactional websites:
“...experts could include people who have used the store’s website to make purchases.” which may possible show that
Google will put more emphasis on reviews that come from actual users of your products.

9. Google has Updated the Quality Raters Guidelines!
4. Who is Responsible for the Website and Who Created Content on the Page
Under the subsection of 2.5 Understanding the website, there’s a new line that adds:
“Websites want users to be able to distinguish between content created by themselves versus content that was added by
other users.”
In another line, Google also emphasizes that they consider it the website’s responsibility to carry the quality of the licensed
or syndicated content, even if it wasn’t created by the website themselves.

5. The Pulitzer Prize is no Longer Depicted as the Only Source of Journalistic Integrity
An interesting development in this version of the Quality Rater Guidelines is that Google is now supplementing any
reference of the “Pulitzer Prize” with other examples of awards or accolades that indicate journalistic quality.
This may have been done because of Google faced backlash for suggesting that the Pulitzer Prize should be the primary
way one should measure the trustworthiness of a news publication.
Furthermore, there is some discussion among conservative publications online that the Pulitzer Prize predominantly
rewards liberal publications, so this change may have been an attempt for Google to appear as more politically neutral.
