Anchor Text Explained
Anchor text is the clickable, visible text of a hyperlink — for example, the words "aged domains" in a sentence that links to a page about them. Search engines have used it since the earliest days of the web as a clue about the topic and relevance of the page a link points to, which is exactly what makes anchor text both a powerful ranking signal and, in the wrong hands, a dangerous one.
That dual nature is why anchor text sits at the heart of backlink analysis. When you examine a domain's backlink profile, the pattern of anchor text across all of its links is one of the fastest and most reliable ways to judge whether that profile grew naturally over years or was assembled artificially to game rankings. A domain's other metrics might look strong, but its anchor distribution frequently tells the real story.
The Main Types of Anchor Text
Before you can read an anchor profile, you need to recognise the categories links fall into. The table below lists the main types with an example for a fictional coffee retailer, and whether large volumes of each look natural to a search engine.
| Type | Example (linking to a coffee shop) | Natural in Large Amounts? |
|---|---|---|
| Branded | "Brutal Coffee" | Yes — the safest, most natural anchor |
| Naked URL | "brutalcoffee.com" | Yes — very common and natural |
| Generic | "click here", "this website" | Yes — normal in editorial content |
| Partial-match | "great coffee beans from Brutal" | In moderation |
| Exact-match | "buy coffee beans online" | No — small share only; high risk |
| Image | (the alt text of a linked image) | Yes — normal |
The key insight from this list is that the anchors real people naturally use — a brand name, a bare URL, or a throwaway "click here" — are the ones that are safe in large quantities, while the keyword-stuffed exact-match anchors that link builders covet are the ones that look suspicious when they pile up. Natural linking simply doesn't produce hundreds of identical commercial phrases.
Healthy Anchor Text Ratios
There is no single official formula for a "correct" anchor profile, but analyses of sites that rank well and avoid trouble show a consistent shape: branded and naked-URL anchors make up the bulk, typically somewhere around 50–70% combined, because that's how people genuinely reference a site. Generic anchors like "here" or "this site" usually account for another 10–20%, and partial-match anchors — which include a keyword wrapped in natural language — sit comfortably in the 5–15% range. Exact-match commercial anchors, the highest-risk category, should be a small minority, often cited at just 1–5%.
What matters far more than hitting these exact percentages is the overall shape. Real sites lean heavily on brand and URL mentions and only occasionally attract a keyword-rich anchor. Manufactured profiles invert that shape, cramming in commercial keywords to chase specific rankings — and it's that inversion, not any single number, that flags a problem. When you review a domain, you're looking for a branded-heavy silhouette, not a precise ratio.
Over-Optimization and Penalties
The reason exact-match anchors are so risky is that Google's Penguin algorithm was built specifically to detect and neutralise this pattern. When a disproportionate share of a domain's anchors are exact-match commercial keywords, it reads as deliberate manipulation, and the consequences are serious. The domain can see its rankings suppressed for the very keywords it over-targeted, it can attract an algorithmic or manual penalty that is slow and painful to recover from, and it will typically show an elevated spam score in third-party tools.
This is precisely why an aged domain with a keyword-heavy anchor profile can be a liability rather than an asset. However impressive its Domain Rating looks, if that authority sits on top of an over-optimized anchor profile, you may be buying a penalty risk that costs more to clean up than the domain is worth.
Checking Anchor Text Before You Buy
Fortunately, anchor analysis is quick once you know what to look for. Pull the anchor distribution from a tool like Ahrefs, which breaks down anchor types across every backlink, and start by confirming the profile is branded-heavy — lots of branded and naked-URL anchors is the signature of natural growth. Then hunt for exact-match spikes: a high percentage of commercial exact-match anchors is a warning, and it's an outright red flag when those anchors are for unrelated or notoriously spammy terms.
Read the anchors in context rather than in isolation. Combine the anchor picture with the dofollow vs nofollow status of the links and the quality of their authority link sources, because over-optimized anchors on low-quality dofollow links is the most dangerous combination. Odd anchor patterns rarely travel alone — they usually accompany the other signs of a manipulated domain, so treat a strange anchor profile as a prompt to dig deeper rather than a standalone dealbreaker.
