Backlink ROI Calculator

The link you're considering

Referring domain authority (DA / DR) Estimated monthly visitors from this link Relevance to your business High — same industry, same country Medium — related industry Low — random directory / unrelated site What you're paying (or the time it costs, valued at £40/hr)

How the value is calculated

Authority value assumes the link is dofollow and actually indexed. A nofollow link's authority value is ~10%. Traffic value uses a conservative £2 per visit for most service businesses.

Quick judgement guide

• DA 60+ relevant link — genuinely valuable; worth £200–£500 if earned or from a real outreach campaign.
• DA 20–40 niche link — modest but real; fine as part of a portfolio.
• DA under 10 or spammy — skip it. It can trigger manual action and costs more in cleanup than it's worth.
• "DA 90 for £50" — almost always a PBN or hacked-site link. Google will devalue or penalise it.

FAQ

How much is a backlink worth?

A good backlink's value depends on the referring domain's authority and relevance. A DA 50+ relevant link can be worth £150–£500+ in SEO value; a spammy link can cost you in penalties.

Should I pay for backlinks?

Buying links violates Google's guidelines and risks penalties. Earn links through digital PR, genuinely relevant guest posts, and free directories. If you do pay, treat it as rented exposure, not an asset.
