Link Strength Score
Before you build or buy a link, grade it. The Link Strength Score is Angle's open, deterministic model: it weighs domain authority, topical relevance and anchor safety into one honest number, with guidance on how to make the link cleaner.
Exact-match keyword anchor. High relevance but the riskiest pattern. Use sparingly and dilute with branded/partial anchors.
1Switch to a branded or partial-match anchor to lift the score and keep the placement natural.
2Your target reads off-topic for the "SaaS & software" cluster. Pick the closest cluster so the link sits in genuinely relevant copy.
How the score works
The score blends three signals: domain authority (how much trust the linking site can pass), topical relevance (how closely the surrounding content matches your target), and anchor safety (whether your anchor text looks natural or over-optimized). Anchor safety deliberately lowers the score for exact-match commercial anchors, because that is the pattern most likely to get a link devalued.
It is a planning aid, not a guarantee. To go deeper, read anchor text ratios without over-optimizing and how to buy backlinks safely.
