Internal linking on a casino affiliate site means deliberately connecting your hub pages, reviews, bonus guides and blog content so link equity — including the equity from your external backlinks — flows to the pages you actually want to rank. Get the structure right and a single strong backlink to your homepage lifts rankings sitewide; get it wrong and that same backlink dead-ends on a page nobody else links to.
It is the half of the equation agencies most often skip. Clients pay for casino backlinks and niche edits, but if the site's own architecture does not route that authority to money pages, a lot of the value never arrives. Here is how to structure it properly.
How should you structure internal links on a casino affiliate site?
Use a hub-and-spoke (silo) model. A top-level hub page — 'Best UK Casino Bonuses' or 'Online Slots Reviews' — links out to every individual review, guide and comparison page in that cluster, and every one of those pages links back to the hub plus sideways to two or three closely related pages in the same cluster.
This does two things at once. It gives Google (and users) a clear path from broad, commercial hub pages down to specific review content, and it means backlinks landing on any page in the cluster — hub or spoke — reinforce the whole cluster rather than one isolated URL. Google's own guidance on link architecture makes this explicit: crawlable, well-structured internal links are how the search engine discovers and understands the relationship between your pages, not just how users navigate.
Breadcrumbs matter more on affiliate sites than most niches because comparison sites tend to be deep — country pages, then game-type pages, then individual operator reviews. Without breadcrumbs and hub-page links, review pages three or four clicks from the homepage become effectively invisible to both crawlers and the internal link equity that would otherwise reach them.
How many internal links does each page need?
Google has said there is no single magical number, but 'if you think it's too much, then it probably is' — which is a useful gut check, not a target to hit. In practice, casino affiliate sites that rank well tend to fall into predictable ranges by page type:
- Homepage / top-level hub pages: 15-40 internal links (navigation plus in-content links to major clusters)
- Category or silo hub pages (e.g. 'Best Live Dealer Casinos'): 10-20 contextual links to child review pages
- Individual review and comparison pages: 3-8 contextual links — related reviews, one supporting guide, one link up to the hub
- Supporting blog and guide content: 3-6 contextual links back into commercial hub and review pages
- Every page on the site: at least one inbound internal link — orphan pages with zero internal links rarely get crawled consistently, let alone rank
What anchor text should you use for internal links?
Descriptive and varied, the same discipline you'd apply to external anchor text strategy for backlinks. Internal anchors get less scrutiny than paid or guest-post links, but a casino comparison site that links to the same review page with the identical exact-match commercial anchor from every single page still reads as manipulative, and it wastes the opportunity to describe what the linked page is actually about.
Mix branded anchors ('read our [Operator] review'), descriptive anchors ('our full live dealer casino comparison') and the occasional exact-match anchor where it genuinely fits the sentence. Avoid generic anchors like 'click here' — Google's SEO Starter Guide flags this explicitly as an anti-pattern, because generic anchor text tells neither users nor crawlers anything about the destination.
How does internal linking multiply the value of your backlinks?
A backlink passes authority to the page it points at. What happens next depends entirely on your internal structure. If that page links onward into your silo — down to reviews, sideways to related guides, up to the commercial hub — the incoming authority spreads through the cluster. If it's a dead-end page with no outbound internal links, the value mostly stops there.
This is why an internal linking audit belongs in the same conversation as how many backlinks a casino site actually needs: a site with a clean silo structure gets more ranking impact from the same number of external links than a flat, poorly linked one. It's also part of why organic traffic and topical relevance track internal architecture more closely than raw Domain Rating alone — a high-authority domain with a broken internal link graph still under-performs sites with cleaner structure and less raw power.
In practice this means: before commissioning a large niche edit campaign or a broader iGaming link building program, audit which pages on the target site actually have a clear internal path to the commercial pages you want to rank. Building external authority into a page that internal linking then fails to distribute is a common and avoidable waste of budget.
What are the most common internal linking mistakes on gambling affiliate sites?
Five mistakes account for most of the lost value we see auditing casino affiliate sites:
- Orphan review pages with no internal links pointing to them — often new operator reviews added without updating the relevant hub page
- Thin hub pages that list operators but don't link to the individual reviews, forcing users (and crawlers) to rely on the main navigation alone
- Homepage-only linking, where new content gets one link from the homepage and nothing else, instead of contextual links from related existing pages
- No breadcrumbs on deep, multi-level comparison sites, which obscures the site's topical structure
- Ignoring YMYL scrutiny — gambling sits in Google's Your Money or Your Life category under its Search Quality Rater Guidelines, and a confusing or manipulative link structure is a worse look here than in a low-stakes niche
