Something awkward has happened to the advice in this category. Read a typical adult-SEO guide next to Google's own spam documentation and a striking number of the recommendations line up with the practices the documentation describes as abuse. Not loosely — closely enough that the guide reads as an instruction manual for getting demoted.
That is not because the advice was cynical when written. Most of it was ordinary and effective for years. It is that in March 2024 Google published three new spam policies and retired one of the metrics the genre had built itself around, and the playbook never caught up.
The advice that became the policy
The single most repeated instruction in adult SEO is to generate a long, keyword-dense description for every clip in a library, because thin and duplicated text ranks poorly. The observation underneath that is correct. The remedy is now the problem.
On 12 March 2024 Google introduced a policy on scaled content abuse, which it defines as generating many pages primarily to manipulate rankings rather than to help users — characteristically by producing large volumes of unoriginal content of little value. A tube library of forty thousand clips, each given a couple of hundred words assembled from a keyword list, is a fairly exact description of the thing that policy names. Nothing in it turns on whether a human or a model wrote the text. The test is what the pages are for and whether anyone is served by them.
The same announcement introduced expired domain abuse — buying a lapsed domain and repurposing it to trade on the reputation it accumulated under a previous owner — and site reputation abuse, hosting third-party content on an established domain to borrow its standing. Enforcement of the third began on 5 May 2024. All three are long-standing tactics in this vertical, and all three are now written down as things that get a site ranked lower or removed altogether.
The practical shift is worth stating plainly. These moved out of the grey area where an operator could reason about risk and into published policy, which means the question stopped being whether the tactic works and became whether the site survives the next enforcement pass.
The metric being optimised no longer exists
The technical half of the standard playbook tells you to watch Core Web Vitals, and specifically to fix First Input Delay.
FID stopped being a Core Web Vital on 12 March 2024. It was replaced by Interaction to Next Paint, and formally deprecated; Chrome tooling stopped guaranteeing its availability on 9 September 2024. The two are not interchangeable. FID measured only the delay before the browser began processing a user's first interaction with the page. INP samples interactions across the whole visit and measures how long until the interface visibly responds. A good INP is 200 milliseconds or under, 201 to 500 needs work, and past 500 is poor.
For a video-heavy site that difference matters more than average. FID could be satisfied by a page that answered its first click quickly and then bogged down under player initialisation, lazy-loaded thumbnails, and several ad libraries competing for the main thread. INP measures precisely that later degradation. Sites that scored well on the old metric can score badly on the new one without a line of code changing.
A statistic worth tracing
One number recurs across this genre: that a 2023 study found pages loading in under three seconds have a 32% higher engagement rate.
There does not appear to be such a study. What exists is a widely cited figure from Google Customer Insights concerning the probability of a bounce increasing by roughly 32% as load time grows. Somewhere in the retelling, a downside risk became an upside gain, the source changed, and a year got attached.
The underlying direction is real and uncontroversial — slow pages lose people. But the specific claim is a mangled inversion of a different measurement, and it is a good illustration of why a citation with no paper behind it should be treated as decoration. If a number in an SEO guide cannot be traced to a document, it is not evidence, whichever way it points.
What actually governs visibility here
The largest factor in adult search performance is one the general-purpose playbook has no reason to mention: this category is filtered by default.
SafeSearch is designed to filter explicit results and is on by default for users under 18. Google's query-understanding systems attempt to determine whether a search is actually seeking explicit material, and its ranking systems work to avoid surfacing it where it was not sought. Explicit content is kept out of AI Overviews. Google publishes a separate document, Guidelines for sites with explicit content, precisely because the general guidance does not describe this situation.
That has a consequence the tactical advice tends to bury. A large share of the discovery surfaces that general SEO now optimises for — AI summaries, zero-click answer panels, recommendation feeds — are structurally unavailable to this category. What remains is direct navigational search, in-site search, and referral. The strategic answer is therefore not the same as it is elsewhere, and a guide that treats adult SEO as ordinary SEO with dirtier keywords has misidentified the terrain.
What survives
Filter the playbook through all of the above and a smaller, duller set of things is still true.
Serve over HTTPS. It is baseline, and it was baseline before any of this.
Fix INP rather than FID, and understand that on a video site the fix is usually about what the player and the ad stack do to the main thread rather than about image compression.
Build a taxonomy that is consistent with itself. Casing that varies between tags, near-duplicate categories, and untitled assets are real problems, and they are problems for the people using the site before they are problems for a crawler. That is the useful reframing: every technical recommendation that still holds is one you could justify to a user without mentioning search at all.
Write descriptions where a description tells someone something they could not get from the thumbnail — and accept that this means writing fewer of them, not more. The volume approach is the one that acquired a policy.
And treat traffic-metric claims, ranking claims and study citations in this space with the same scepticism you would apply to a catalogue-size claim on a tube site. The genre has an accuracy problem, and this article exists mostly because the last version of it had one too.
