⚙ Simple Calculation Overview

1. Current traffic = Volume × 0.15 × CTR(your position)
2. Top-3 traffic = Avg CTR(top-3) × Volume × 0.15
3. Traffic gap = Top-3 traffic − Current traffic
4. Revenue leak = Traffic gap × Conversion rate × Close rate × 0.90 × LTV

Key assumptions: Qualified traffic factor (0.15), cannibalization discount (0.90), 24-month linear projection. All scenarios use the same inputs but different multipliers.

📈 Example Walkthrough

Search volume5,000/month
Position#11 (2.9% CTR)
Current traffic22 visits/month
Top-3 traffic113 visits/month
Traffic gap91 visits/month
Revenue leak (standard)$1,377/month

Results vary based on your inputs and the selected CTR model.

⚙ Locked Constants

Qualified Traffic Factor (Q)0.15
Cannibalization Discount (K)0.90
Conservative Multiplier0.75×
Optimistic Multiplier1.25×
Projection Period24 months (linear)

Conservative internal assumptions. The 24-month figure is cumulative linear — not compounding.

📈 Full Formula Chain

1. T_current = V × Q × CTR(P)
2. T_target = Avg(CTR(1), CTR(2), CTR(3)) × V × Q
3. ΔT = T_target − T_current
4. ΔLeads = ΔT × C_site
5. ΔSales = ΔLeads × C_sales × K
6. Leak_monthly = ΔSales × LTV × Scenario
7. Leak_24mo = Leak_monthly × 24

V = Volume • Q = 0.15 • P = Position • C_site = Conv. Rate • C_sales = Close Rate • K = 0.90

It translates poor search rankings into a dollar figure. Enter your keyword's monthly volume, your current position, and customer LTV — the calculator shows the 24-month revenue you're leaving on the table by not ranking in the top 3.
Yes. The plugin is free to download and use, with no trial period or feature gating. The only requirement is a do-follow backlink to linkcheck.app on the site where it's installed — a fair exchange for a free, white-label-ready tool.
Never. All lead data stays entirely in your WordPress database. linkcheck.app never receives, stores, or touches your leads. You can route them to email or a webhook, but that's your choice — not ours.
The widget interface is fully white-labeled — there is no linkcheck.app branding on the public-facing calculator. The only linkcheck.app branding appears in your WordPress admin dashboard. The free license requires one separate attribution link somewhere on your website.
