When I talk to site owners about link building, they're focused on one metric: how many links. The quality of those links matters, of course, but there's a third variable that gets almost no attention: what those links actually say. Anchor text is how Google reads the intent and topic of a link. Get it wrong and your link profile can end up hurting you more than helping.
What Anchor Text Signals to Google
Google uses anchor text as a relevance signal. When a page links to you with the anchor text "best running shoes for flat feet," it's telling Google that your destination page is relevant to that topic. Enough links with similar anchors and Google starts associating your page with that concept. That's the positive case.
The risk: Google also uses anchor text patterns to detect manipulation. If 40% of your backlinks use the exact phrase "buy cheap SEO tools," that looks like someone built those links specifically to rank for that keyword. It doesn't look like natural editorial linking. That's what Penguin was built to catch.
Natural links use varied, often imprecise anchor text. When someone links to a useful resource, they usually link with the page title, the brand name, or "this article" or "here." They rarely link with a keyword-optimized phrase unless they're writing a very specific recommendation.
The Natural Anchor Text Distribution
Studies of natural link profiles from sites that rank well consistently show the same pattern. The exact numbers vary by site and industry, but the rough breakdown looks like this:
- Branded anchors (your company name, brand variations): 30-40%
- Naked URL anchors (yoursite.com, www.yoursite.com): 20-30%
- Generic anchors ("click here," "read more," "this article," "here," "source"): 15-20%
- Partial match (phrases that contain your keyword but aren't exact): 10-15%
- Exact match (the precise keyword you're targeting): 2-5%
Notice how small that exact-match number is. Real editorial links don't look like an SEO strategy. A lot of link builders get this inverted — they're actively seeking exact-match anchors because that's intuitively what feels most powerful. And it is more powerful, per link. But the aggregate pattern you're building toward can kill you.
The Penguin History and What "Too Many" Looks Like
Google's Penguin algorithm launched in April 2012 specifically to target manipulative link building, with anchor text over-optimization as one of the primary signals. Sites that had spent years building exact-match anchor links got hit hard. Some never recovered.
Penguin became part of Google's core algorithm in September 2016, meaning it now runs in real time rather than on refresh cycles. The practical implication: you don't wait 6 months to see the penalty anymore. But recovery from anchor text over-optimization is a longer, slower process than it used to be.
What does "too many" look like? There's no hard threshold Google publishes, obviously. But patterns I've seen cause problems:
- Exact-match anchors exceeding 15-20% of the link profile
- A handful of anchors accounting for 80%+ of all links (lack of diversity itself is a signal)
- Sudden spikes in exact-match anchors over a short time window
- Exact-match anchors predominantly coming from low-quality, thin content sites
High-authority links with exact-match anchors are less concerning. A link from the New York Times that happens to use your target keyword as anchor text is fine. The problem is when exact-match anchors are concentrated in low-quality link sources, which suggests they were placed rather than earned.
How to Audit Your Anchor Text Profile
You need a backlink data source for this. Ahrefs, Semrush, and Moz all have anchor text reports. The process:
- Pull your full backlink profile from one or preferably two tools (coverage varies between them)
- Export the anchor text data and categorize each anchor: branded, naked URL, generic, partial match, exact match
- Calculate percentages for each category
- Flag any anchor that appears more than 5-10 times with exact-match phrasing
- Check whether the exact-match anchors are coming from authoritative sources or low-quality sites
Red flags in an audit: one anchor phrase accounting for 20%+ of all links, a sudden jump in exact-match anchors in a 2-3 month window, groups of links from obviously related sites all using identical anchor text.
If you find a concentration problem, the fix is not to remove the over-optimized links (unless they're genuinely toxic). The fix is to build more branded and generic anchor links to dilute the ratio. If you have a disavow-worthy situation (links from spam networks, PBNs, link schemes), then yes, disavow and start rebuilding with a healthier distribution.
The Ratio to Aim For
My working targets for a healthy, natural-looking anchor profile:
- 60-70% branded + naked URL: The majority of your links should reference your brand or URL. This is what natural linking looks like.
- 20-30% generic: "Click here," "read more," "source," "via," "reference." These are low-value individually but important for the distribution pattern.
- 5-10% partial match: Phrases that include relevant keywords but aren't exact. "Affordable running shoes" when your target keyword is "cheap running shoes."
- 2-5% exact match: Your primary target keyword, used sparingly. Each one carries significant weight precisely because they're rare.
These are targets, not rules. A brand-new site will have a different distribution than a 10-year-old site. Industry matters too. Technical documentation sites tend to have more naked URL and generic anchors. Review sites tend to have more partial and exact match. Use your judgment and check what your top-ranking competitors' profiles look like.
How to Request Better Anchor Text in Outreach
When doing manual outreach for links, you have an opportunity to shape the anchor text — but you need to do it tactfully. Directly asking for an exact-match anchor ("can you link to us using the phrase 'best SEO tools'") sounds like spam and will reduce your acceptance rate.
More effective approaches:
Suggest the anchor in context: Instead of requesting a specific anchor, provide the sentence context. "Feel free to link to the tool as 'FreeSEOTools' or whatever feels natural in your text." You're steering toward branded without being demanding.
Lead with the title: If someone links to your post called "The Complete Guide to Anchor Text," they'll often use the title as anchor text naturally. Writing posts with descriptive, keyword-adjacent titles means your natural link anchors tend to be partially optimized without any manipulation.
For partial match opportunities: If you're adding a link to someone's existing article and they're letting you suggest anchor text, propose something that sounds natural in context. "anchor text optimization" instead of "anchor text SEO guide" reads as less manufactured.
The goal is a profile that looks like you got links because people found your content useful, not because you have a link building operation. The sites with the healthiest anchor profiles aren't thinking about anchor text ratios — they're building things worth linking to and the distribution takes care of itself. But if you're actively building links, it's worth checking the math every few months to make sure you're not drifting into dangerous territory.
