SEO KPIs

SEO KPIs (key performance indicators) are the metrics used to measure whether SEO work is succeeding. The best KPIs connect search performance to business outcomes, so you can tell not just whether rankings improved, but whether SEO brought more customers.

Business outcome KPIs

These matter most, because they show the real value of SEO:

Organic conversions: enquiries, calls, bookings, sign-ups or sales from organic search.
Organic revenue: for ecommerce, the value of sales from organic traffic.
Organic conversion rate: the percentage of organic visits that convert.
Cost per acquisition from SEO: SEO investment divided by organic conversions, useful for comparing with paid channels (SEO vs PPC).
Lead quality: how many organic leads become customers, tracked in your CRM.

Traffic and engagement KPIs

Organic sessions and users from Google Analytics 4.
Organic clicks from Google Search Console.
Engagement rate and time on page for organic visitors.
Non-branded organic traffic, which shows growth beyond people who already know you (Branded Search).
Traffic to priority pages, such as service and product pages.

Visibility KPIs

Impressions: how often your pages appear in search results.
Rankings for priority keywords (Rank Tracking).
Share of voice: your visibility compared with competitors across a keyword set.
Number of ranking keywords, especially on page one.
SERP feature ownership: Featured Snippets, map pack positions and AI citations.
Click-through rate: the percentage of impressions that become clicks.

Health and authority KPIs

Indexed pages vs pages you want indexed.
Core Web Vitals pass rate.
Referring domains from relevant, trusted sites.
Review count and rating for local businesses.

How to choose your SEO KPIs

Start with the business goal: more leads, more sales, more bookings in a new area.
Pick one or two primary KPIs that reflect that goal directly.
Add supporting KPIs that explain why the primary KPIs move.
Set a baseline before starting work.
Agree realistic targets and timeframes; SEO usually needs months to show results.
Segment by branded vs non-branded, page type and location.

KPIs to treat with caution

Average position: an average across all queries can be misleading; track specific keywords instead.
Total traffic alone: traffic that does not convert may not matter.
Third-party authority scores: useful context, not goals (Domain Authority).
Bounce rate: GA4 uses engagement rate instead, and a single-page visit that ends in a phone call is a success.

Reporting KPIs

Present KPIs in a simple monthly report that shows trends, explains changes and lists next actions. See SEO Reporting for structure and tips.
