Link Building Fundamentals
Anchor text is the visible, clickable part of a link — the words you press to travel to another page. To a reader it's a signpost; to a search engine it's a description of the destination written by someone other than the destination's owner, which makes it one of the most trusted relevance signals in ranking. It is also, for exactly that reason, one of the easiest ways to get a site in trouble when over-optimised.
This guide covers the anchor text types, how search engines read them, and the best practices that keep the signal working for you instead of against you.
How search engines use anchor text
In HTML, anchor text lives between the tags: <a href="https://example.com/running-shoes/">best trail running shoes</a>. When Google crawls that link, the phrase "best trail running shoes" becomes evidence about what the destination page covers — evidence Google has used since its earliest days, because thousands of independent describers are harder to fool than one site describing itself.
Harder, but not impossible — which is why the Penguin algorithm (2012, now baked into the core systems) specifically targets profiles where the describing was clearly orchestrated: hundreds of links all "describing" a page with the same money keyword. Anchor text is a classic dual-use signal: natural variety helps you rank, manufactured uniformity gets you filtered.
The anchor text types
1. Exact match
The anchor is precisely the keyword the page targets: anchor text linking to this page. The strongest relevance signal per link — and the most dangerous in volume, because natural linkers rarely all choose your exact keyword.
2. Partial match / phrase
The keyword appears inside a longer natural phrase: a solid guide to anchor text best practices. Passes strong relevance with far less pattern risk. The workhorse anchor of healthy profiles.
3. Branded
BacklinksMedia, according to Moz — the linking site names you. Typically the largest slice of a natural profile, and the anchor Google most expects to see pointing at a real business.
4. Naked URL
The address itself as the anchor: backlinksmedia.com. Common in citations, directories and forums; neutral and entirely natural-looking.
5. Generic
Click here, read more, this article. Carries almost no relevance signal, but its presence is a mark of authenticity — real linkers are frequently lazy describers.
6. Image anchors
When an image is the link, its alt text serves as the anchor. If you distribute infographics or product photos, those alt attributes are doing anchor duty for every embed.
7. Long-tail / natural sentence
A whole descriptive phrase: this breakdown of how anchors affect rankings. Increasingly common, entirely safe, and often the most useful to readers.
Anchor text best practices
Write for the reader first
The anchor should tell a person what they'll get when they click — descriptive, specific, never deceptive. That single rule produces roughly the distribution search engines consider natural, no spreadsheet required.
Keep exact match rare
Reserve exact-match anchors for your few most authoritative placements, and let partial-match and natural phrasing carry the relevance elsewhere. If you control the anchor (guest posts arranged through outreach or via our publisher network, for instance), vary it every single time — the profile-level maths is covered in our anchor text ratio guide.
Let earned links describe you however they like
When a journalist links to you with "this study" — leave it. Emailing sites to change anchors toward keywords creates the exact orchestration pattern the algorithms hunt. Editorial randomness is a feature.
Use internal links for precision
On your own site you can be as descriptive as you like, safely. Internal anchors like what is a backlink or link building guide tell crawlers exactly what each destination covers — internal anchor text is scrutinised far less for over-optimisation and does real work for topic clusters. Avoid only the silly extreme of every internal link being the same phrase.
Mind the surrounding sentence
Google reads context around a link, not just the anchor itself. A link placed mid-argument in a relevant paragraph beats the same anchor floating in a list of unrelated links — placement is part of the signal.
Auditing your anchor profile
Any backlink tool (Ahrefs, Semrush, Moz) shows an anchors report for your domain. Look for one thing above all: does any single money keyword dominate? A healthy profile is led by branded and URL anchors with keyword anchors scattered thinly behind. If one commercial phrase accounts for a suspicious share of your links, stop acquiring it entirely and let dilution do its slow work. Not sure how bad yours looks? Send it over — we read anchor reports every day.
Frequently asked questions
What is the ideal anchor text distribution?
There's no universal ratio — natural profiles differ by niche. Direction is what matters: branded + URL anchors should lead comfortably, and exact match should be a single-digit percentage. We break down safe ranges in the distribution guide.
Does anchor text matter for nofollow links?
Far less — nofollow links generally pass neither equity nor much anchor signal. Their value is traffic and visibility, whatever the anchor says.
Can bad anchor text hurt me if I didn't build the links?
Random spam anchors pointing at you are normal web noise and Google largely ignores them. The risk pattern is volume + uniformity + commercial keywords — the fingerprint of a campaign, which spammers pointing junk at you rarely bother to fake.
