Slot game pages: which ones to index and what to put on them

Most casino lobbies hold thousands of slots, but only a small share deserve indexable pages. Here is how to tier them and what to put on the ones that rank.

Row of slot machines representing a large casino game catalogue

A typical licensed casino lobby holds several thousand slots, and most platforms generate a URL for every one of them. The result is thousands of near-identical pages: a game thumbnail, a "play" button and a description copied from the provider's press kit. Search engines index a fraction of them, rank fewer, and spend crawl budget on the rest.

The fix is not to write 3,000 unique descriptions. It is to decide which slot pages deserve to be in the index, build those properly, and keep the others available to players without asking search engines to evaluate them. This article sets out the tiering we use and what goes on each type of page.

Why most slot pages should not be indexed

Most slot pages should not be indexed because they have no search demand and no unique content. Only a small share of games in a large catalogue attract meaningful searches by name, usually the well-known titles, recent releases from major providers and long-running classics. The rest duplicate provider copy that appears on hundreds of other casino and affiliate sites, which makes them thin by any search engine's standard.

On casino audits we typically see the same picture. Of a catalogue of 3,000 to 6,000 games, somewhere between 5% and 15% have measurable search demand in a given market. The remaining pages produce close to zero organic sessions, yet they often take a large share of Googlebot requests in server logs. When thin pages dominate a site section, the good pages in that section tend to suffer too, because the section as a whole looks low value.

How to decide which slot pages to index

Decide which slot pages to index by combining search demand, commercial value and your ability to add unique content. A game earns an indexable page if people search for it by name in your market, if it is available under your licence there, and if you can publish information that is not already on every competitor's page. Review the list quarterly, because demand moves with releases.

The inputs we use for each game:

Search demand: monthly searches for the game name plus modifiers such as "slot", "demo", "RTP" and "review" in the target market.
Availability: whether the game is live under the licence in that market. A game that is geo-restricted should not have an indexable page there.
Performance: lobby data on plays and retention, which helps prioritise games where users will find what they searched for.
Content capacity: whether your team can verify and add facts the provider sheet does not cover.

Our guide to iGaming keyword research covers how to size game-name demand per market.

Tier 1 slots: index and build full pages

Tier 1 slots are the games with clear search demand and strategic value in the market, typically the top 50 to 200 titles. They get indexable pages with a full template: verified game facts, an original description written by someone who has reviewed the game, feature explanations, screenshots, related games and responsible gambling information. These pages are listed in the sitemap and linked from category and provider pages.

Tier 1 pages are where editorial effort pays back. A useful page answers what a searcher actually wants to know about the game before they decide whether to open it, and it does so in plain language rather than marketing copy. Write from review, not from the press release. If the reviewer cannot confirm a feature, leave it out.

Tier 2 slots: index with a lighter template

Tier 2 slots have modest but real search demand, for example mid-popularity titles or recent releases still building interest. They get indexable pages with a lighter template: structured game facts, a short original summary of 100 to 200 words, the main features and links to related games. They stay in the sitemap and are promoted to Tier 1 or demoted to Tier 3 at the quarterly review.

The structured facts block does most of the work on Tier 2 pages. Pulled from the provider feed and checked against the live game, it gives each page specific, accurate information even when the editorial text is short. Generate the facts block from data, but never generate the summary paragraph from a template that only swaps the game name.

Tier 3 slots: keep in the lobby, out of the index

Tier 3 slots are the long tail with no measurable search demand. They stay fully available to players in the lobby but are kept out of the index. Either the platform opens them without a standalone URL, or their pages carry a noindex directive and are excluded from the sitemap. This keeps crawl activity on pages that can rank without removing any game from the product.

Two implementation notes. If you use noindex, do not also block those URLs in robots.txt, because crawlers then cannot see the noindex directive. And make sure the lobby, filters and search results that link to Tier 3 games are not themselves generating crawlable parameter URLs, which is the more common source of crawl waste.

Tier	Typical share of catalogue	Indexing	Template	In sitemap
Tier 1	Top 50 to 200 titles	Index	Full: verified facts, original review, screenshots, related games	Yes
Tier 2	Next few hundred titles	Index	Light: facts block, 100 to 200 word original summary	Yes
Tier 3	Remaining long tail	Noindex or no standalone URL	Lobby tile only	No

What a ranking slot page contains

A ranking slot page contains accurate, verifiable game facts, an original description of how the game plays, an explanation of its features, real screenshots, links to related games and the provider page, and responsible gambling information. It avoids promises about winning, unverifiable claims and copied provider text. The facts should reflect the version of the game actually offered on your site in that market.

The facts block

Provider and release date.
Reels, rows and paylines or ways to win.
RTP for the version you offer. Providers often release several RTP configurations of the same game, so state the figure that applies on your site rather than the highest one in the press kit.
Volatility as described by the provider, labelled as such.
Minimum and maximum stake under the rules of your market, which may be lower than the provider default.
Maximum win as stated by the provider.

The editorial part

Describe the theme, the base game, how bonus features trigger and what they do, and who the game suits in terms of pace and volatility. Explain mechanics such as cascading reels or multipliers in plain terms. Do not describe a game as "high paying" or suggest strategies to win. RTP is a long-run theoretical figure, and the page should say so. This is the standard our content creation team writes game pages to.

Demo play, compliance and market differences

Demo play, stake limits and promotional language differ by market, and slot pages must reflect the rules where they are served. In Great Britain, for example, free-to-play demos must sit behind age verification, so a public demo cannot be the main content of an indexable page. Other regulated markets set their own stake limits and product rules, which should be reflected in each localised page.

Practical consequences for slot page templates:

Do not rely on an embedded demo as the page's content. Write the page so it is useful without it.
Show market-specific stake limits and game availability, not the international defaults.
Keep bonus offers off game pages unless the full terms can sit next to them, and check the advertising code of each market.
Remove or noindex pages for games withdrawn from a market, and redirect them to the provider or category page.

The current British rules are published by the Gambling Commission. Check the regulator in each other market, because demo and stake rules change.

Provider and category pages as the link layer

Provider and category pages are the link layer that connects slot pages to the rest of the site. They collect broader searches such as a provider name plus "slots" or a mechanic such as "megaways slots", and they pass internal authority to Tier 1 and Tier 2 game pages. Each should carry original introductory content and a curated, crawlable list of indexable games.

Keep the number of category pages under control. A category earns an indexable page if it matches a real search pattern and holds enough games to be useful. Thin combinations, such as a filter for a provider and a theme and a volatility level, belong in the lobby, not the index. The same rules apply on online casino SEO projects of any size.

Key point: A casino with 200 strong slot pages and 3,000 games in the lobby usually outranks a casino with 3,000 thin slot pages. Index for demand, not for catalogue size.

Frequently asked questions

How many slot pages should a casino index?

There is no fixed number. Index the games that people search for by name in your market, that are available under your licence and that you can describe with original, verified content. On large catalogues this usually means a few hundred pages out of several thousand games. Review the list quarterly as new releases change demand.

Should slot pages use noindex or robots.txt?

Use noindex for slot pages you want kept out of search results, and do not block those URLs in robots.txt at the same time. If crawlers cannot fetch the page, they cannot see the noindex directive. Alternatively, open long-tail games in the lobby without creating standalone URLs, which avoids the problem entirely.

Which RTP figure should a slot page show?

Show the RTP of the game version actually offered on your site in that market. Many providers release several RTP configurations of the same title, and the press kit often quotes the highest. Label RTP as a long-run theoretical figure and avoid any wording that suggests players can expect to win.

Can a demo game be the main content of a slot page?

It should not be. In Great Britain free-to-play demos must sit behind age verification, so crawlers and unverified visitors will not see them. Other markets have their own rules. Write the page so it is useful without the demo: verified facts, an original description of features and links to related games.
