Free backlink ROI calculator
You paid $400 for a link placement. Was it worth it? Enter the keyword's monthly search volume from Ahrefs or Semrush, pick your expected ranking position, and this calculator uses the Advanced Web Ranking 2024 CTR curve to estimate the monthly traffic, revenue contribution, and time-to-breakeven. Everything runs in your browser — nothing is sent anywhere.

Fill in link cost and monthly search volume to see your ROI estimate.
Numbers are estimates. CTR from AWR 2024; conversion rate is an editable default. Projections assume the target position holds for the full horizon with no ranking ramp.
How the ROI calculation works
No proprietary scores, no hidden weights. Every number in this backlink ROI calculator is derived from inputs you control, and the CTR data is cited so you can verify it.
The CTR curve
To go from "ranking position" to "monthly visitors," the calculator uses click-through rate data from the Advanced Web Ranking 2024 industry study. These are blended organic CTRs across desktop and mobile:
| Position | CTR (organic, blended 2024) |
|---|---|
| 1 | 27.6% |
| 2 | 15.8% |
| 3 | 11.0% |
| 4 | 8.4% |
| 5 | 6.3% |
| 6 | 4.9% |
| 7 | 3.9% |
| 8 | 3.3% |
| 9 | 2.7% |
| 10 | 2.4% |
Your actual CTR depends on your title tag, meta description, SERP features like featured snippets or Shopping boxes, and niche-specific user behaviour. The AWR values are averages — treat them as a plausible middle estimate, not a guarantee.
From traffic to revenue
Monthly traffic = search volume × CTR at your target position. Revenue per month = traffic × conversion rate × average order value. Breakeven = link cost ÷ monthly revenue. ROI = (cumulative revenue – link cost) ÷ link cost, expressed as a percentage.
Cumulative revenue assumes you hold the target position for every month of the horizon, with no ramp-up delay. That is optimistic. For a more conservative number, use a shorter horizon (6 months instead of 12) or a lower target position.
What the verdict thresholds mean
Strong ROI (over 300%) — At these numbers, the link pays for itself roughly 4× over the horizon. Good case for placing the link on revenue grounds alone.
Moderate ROI (50%–300%) — The link should pay for itself before the horizon closes. Reasonable investment if the ranking materialises.
Weak ROI (0%–50%) — Marginal. The revenue math barely covers costs. Factor in non-revenue benefits (domain authority, anchor diversity, referral traffic) before deciding.
Negative ROI — Under these assumptions, the link costs more than it returns in direct revenue over the horizon. That isn't necessarily a hard no — but the pure revenue case doesn't support the spend.
What this calculator does not measure
A few things matter that the numbers can't capture. Domain authority uplift from a strong donor improves rankings on other pages too — that value doesn't show up here. Anchor text diversification matters if your profile is over-optimized on exact-match. Referral traffic from the donor page is real even if the ranking never materialises. And brand exposure on an authoritative site in your niche has value that CPC math won't reflect.
Treat the ROI figure as the floor of the case for the link — the conservative revenue-only argument. For most well-chosen placements, the full case is stronger.
Where to get the keyword's monthly search volume
- Ahrefs: Keywords Explorer → search your target keyword → the "Volume" figure is the estimated monthly searches.
- Semrush: Keyword Overview → "Volume." The Keyword Magic Tool lists volume for every related keyword too.
- Google Keyword Planner: Free — shows an "Avg. monthly searches" range for any keyword.
Search volume is the number of times people search the keyword each month. The calculator applies the position-based CTR curve to it, so the visit estimate already accounts for the fact that only a fraction of searchers click any single result — and that fraction shrinks the lower you rank.
Frequently asked questions
How does the backlink ROI calculator work?
You enter the cost of the link placement, the monthly search volume of the target keyword (from Ahrefs, Semrush, or Google Keyword Planner), the ranking position you expect to reach, your site's conversion rate, average order value, and a time horizon. The calculator applies a real CTR curve to the search volume to estimate monthly visits, multiplies by your conversion and order-value inputs to get monthly revenue contribution, then divides cumulative profit by link cost to produce the ROI ratio and breakeven figure.
Where do I find the keyword's monthly search volume?
In Ahrefs: Keywords Explorer → "Volume" column. In Semrush: Keyword Overview → "Volume." Google Keyword Planner shows an "Avg. monthly searches" range for free. Enter that number — the calculator applies the position-based CTR curve to it to estimate how many of those searchers actually click through to your page at your target ranking.
What CTR data does this calculator use?
The CTR curve is from Advanced Web Ranking's 2024 industry study. Position 1: 27.6%, position 2: 15.8%, position 3: 11.0%, position 4: 8.4%, position 5: 6.3%, position 6: 4.9%, position 7: 3.9%, position 8: 3.3%, position 9: 2.7%, position 10: 2.4%. These are blended averages — your actual CTR will vary by niche, SERP features, and meta quality.
What conversion rate should I use?
The default is 2%, which is a rough benchmark for B2B SaaS. It is not sourced from your own data. Your real conversion rate could be much higher or lower. If you have real conversion data from Analytics or your CRM, use that — it will make the projection far more accurate than any industry default.
Why does the ROI estimate assume I rank at the target position immediately?
It does, and that is a known limitation. Rankings typically take 3–6 months to appear after a link is placed, and they fluctuate. Use a shorter time horizon (6 months instead of 12) to get a more conservative estimate that bakes in the ranking delay.
Does the calculator account for link value beyond revenue?
No. Domain authority uplift, anchor diversification, referral traffic, and brand exposure are not in the model. The ROI figure is the revenue floor — the conservative minimum case. For many well-chosen placements, the full case is stronger once you factor in those extras.
What does the verdict mean?
Strong ROI (over 300%) means the link looks worth it on pure revenue grounds. Moderate (50%–300%) means reasonable if the ranking holds. Weak (0%–50%) means marginal on revenue alone — factor in non-revenue benefits. Negative means the revenue doesn't justify the cost under these assumptions. None of these are verdicts from Google; they are heuristic thresholds based on the revenue math you entered.
What is a good ROI for a paid backlink?
There is no universal answer. A $100 link that generates $50 in monthly revenue is a 2-month breakeven — compelling. A $2,000 placement for a competitive keyword might take 18 months to break even, which is fine if the domain authority uplift accelerates other rankings in the meantime. The calculator helps you frame the revenue math; the decision is yours.
