Guidelines for sites with explicit content

Many users prefer not to have explicit content shown in their search results, and Google has
systems in place to help users filter explicit content. If your site hosts explicit or adult
content, you can help Google understand the nature of your site and content, which can help
Google to more accurately categorize your site and ensure user preference regarding explicit
content.

How Google handles explicit content in Search results

Google uses multiple systems to protect users from being exposed to unexpected explicit results.
Our algorithms detect user intention and rank results accordingly, weighing result quality and
the relevance of explicit results to user queries. With SafeSearch, we help users to filter out
explicit content.

How SafeSearch works

SafeSearch is designed to filter results that lead to visual depictions of:

• Explicit sexual content of any type, including pornography
• Nudity
• Photo-realistic sex toys
• Sex-oriented dating or escort services
• Violence or gore
• Links to pages containing explicit content

For example, SafeSearch is designed to filter out pages that contain images or videos that
contain exposed breasts or genitals, as well as to filter pages with links, pop-ups, or ads that
display or point to explicit content. It also aims to allow explicit content when it has an
educational, documentary, scientific, or artistic (EDSA) value. SafeSearch relies on automated
systems that use machine learning and a variety of signals to identify explicit content,
including text, images, and videos on the hosting web page and in links.

Even when SafeSearch is off or set to blur, Google’s ranking and language understanding systems
work to prevent unwanted exposure to sexually explicit and graphic violent content. Using query
understanding algorithms, Google Search is designed to detect whether searches are seeking out
explicit content, helping reduce the chances of encountering unwanted explicit search results.

Regardless of your SafeSearch setting, Google removes pages that violate our
content policies (such as child
sexual abuse material). We also remove pages upon user request for
personal information removal
(for example content involving explicit personal imagery created or shared without consent,
или explicit non-consensual fake content).

How Google handles sites with a significant amount of removals of violative sexually explicit content

If we process a significant volume of valid removal requests involving a particular site, we use that as
a signal to improve our results. In particular, regarding sexually explicit content:

• CSAM removals: We always remove child sexual abuse material (CSAM) when it’s
  identified, either automatically or through the legal removals process. We also demote all
  content from sites with a significant proportion of CSAM content.
• Explicit personal information removals: We demote all pages from sites that receive a
  significant volume of personal removals of content involving
  explicit personal imagery created or shared without consent
  или explicit non-consensual fake content.

and spam policies.

Best practices

By following these best practices, you not only help ensure that users see the results they expect
and foster a safer online environment for everyone, but also help ensure your target audience can
find your content through Google Search.

1. Prevent user-generated harmful content on your platform.
2. Allow Google to fetch your video content files.
3. Allow Googlebot to crawl without age gate.
4. Group explicit pages in a separate domain or subdomain.
5. Mark specific pages as explicit with metadata.

Prevent user-generated harmful content on your platform

To foster a safer online environment for users, we recommend that platforms featuring sexually
explicit content implement publisher verification and content moderation processes. Adopting these
measures is a best practice that helps manage content responsibly and mitigate risks associated
with potentially harmful or illegal material, such as CSAM and
non-consensual explicit content.

Implementing proactive CSAM detection in user-generated
content

To prevent the distribution of child sexual abuse material, we recommend that platforms use
industry-standard techniques such as hash matching for detecting known violative content and
classifiers for detecting novel content. By proactively identifying and flagging potentially
violative content, you can significantly enhance the safety of your platforms and contribute to
the broader effort of combating child exploitation.

Allow Google to fetch your video content files

Allowing Googlebot to fetch your video files
enables Google to understand the video content and reduces the chance of exposing users to
violative explicit content, such as CSAM and non-consensual explicit content.

If you don’t allow Google to fetch your video content files, Google can’t run automated
protections against egregious violations such as CSAM.
Content that can’t be fetched may pose a risk to our users, so Google may demote or filter such
pages where the embedded video content is unavailable and our automated systems determine that
the page may contain explicit content. Not allowing Googlebot to fetch your video files may
significantly affect the ranking of your explicit pages on Google Search, and especially in Video
mode.

Allow Googlebot to crawl without age gate

If you have content behind an age gate or other access restriction, be sure to allow Googlebot to
crawl your content without triggering the age gate. You can do this by
verifying Googlebot requests and
serving the content without age gate.

If you don’t allow Googlebot to crawl without triggering the age gate, it may cause your site to
rank poorly on Google Search. Google might not be able to fetch your content, including image or
video bytes, and therefore not be able to effectively rank that page for relevant queries.
Additionally, if you host some non-explicit content behind age-gate and Googlebot cannot see it,
there is a higher chance that this content or even the whole site gets classified automatically
as explicit, which will make it ineligible to appear when the SafeSearch filter is on.

Group explicit pages in a separate domain or subdomain

If your site contains significant amounts of explicit content and non-explicit content, we
recommend grouping the explicit pages on a separate domain or subdomain. For example, you could
host your explicit pages on https://explicit.example.com/..., and your non-explicit
pages on https://www.example.com/....

If you don’t group pages separately, our systems might determine that your entire site seems
explicit in nature and filter the entire site when the SafeSearch filter is on, even if some pages
might not be explicit.

Mark specific pages as explicit with metadata

Google has algorithms to automatically detect explicit pages, including text, images, and videos.
While not necessary, adding metadata can be be a practical way for you to tag a few explicit pages
on your site or if you want to be sure that a particular page is filtered for SafeSearch users:

• Add metadata to pages with explicit content.
• Use the <video:family_friendly> tag in your video sitemap.

Add metadata to pages with sexually explicit content

To mark a particular page as explicit, add rating markup
with the adult value either as a
meta tag or an HTTP response header.
We recommend adding this tag to any page with sexually explicit content.

Google also recognizes <meta name="rating" content="RTA-5042-1996-1400-1577-RTA">
as an equivalent way to identify pages with sexually explicit content. Either tag is fine; it’s
not required to add both tags.

Use the <video:family_friendly> tag in your video sitemap

If you have a range of videos on your site, including content appropriate for all ages as well as
sexually explicit or content that contains graphic violence, make use of the
<video:family_friendly>
tag in your video sitemap. You only need to use this tag (set to no) for
videos that are explicit. This helps Google understand which videos on your site shouldn’t appear
when SafeSearch filtering is enabled.
