How to measure a funnel content guide

Measure a funnel guide by stage, because each stage has a different job. TOFU (top of funnel) articles are judged on search visibility and on whether readers click through to the next article. MOFU (middle of funnel) articles are judged on whether readers move on to comparison, cost and service pages. BOFU (bottom of funnel) pages are judged on leads. A guide that gets lots of TOFU traffic and no BOFU leads has a problem; a TOFU article with no leads of its own may be doing its job.

In practice that means three layers of measurement. Search Console, filtered to the guide's pages, shows visibility in Google Search, including an impressions-only view of AI Overviews and AI Mode. GA4, with pages tagged by stage, shows what readers do on the site. Key events and lead records, tagged by topic, show which parts of the guide produce inquiries. None of the tools labels your pages by funnel stage, so the stage labels are yours to add.

Decide what each stage is judged on

Write this down before the first report, so nobody judges a TOFU article on leads or a BOFU page on traffic.

Why TOFU pages often earn visits without inquiries is covered in why top-of-funnel content gets traffic but not leads.

Search Console: group the guide's pages

The Performance report shows clicks, impressions, click-through rate and average position. To see the guide alone, filter by page.

• If the guide has its own folder, such as /guide/, add a Pages filter with "URLs containing" and the folder path.
• If stage isn't in the URL, use a regex filter. Google's steps: click + Add filter, choose Pages, choose "Custom (regex)" and enter the expression. List several slugs separated by a vertical bar to build one group per stage. Google uses "RE2 syntax", matches anywhere in the URL by default, and ignores case by default.
• Compare periods. Use Compare for two date ranges. Search Console allows one comparison at a time.
• Split branded queries. The branded and non-branded filter separates searches that include your brand name. Google says it "isn't available for sites with a low number of impressions."

Two limits matter for big guides. Tables show at most 1,000 rows, and Google says collected data "is usually available in 2–3 days." Export monthly, keep a sheet of stage groups, and add a custom annotation to the chart when you launch or update a batch.

The Page indexing report belongs in the same routine. If the guide has its own sitemap, filter the report to that sitemap to see which guide pages are indexed and why others are not.

The Generative AI performance report

Search Console's Generative AI performance report shows how often links to your site appeared in AI Overviews and AI Mode. Google rolled it out to all websites worldwide as of August 31, 2026. What it shows, as of October 2026:

• One metric: impressions. Google defines them as "how many times links to your site were shown to a user in a generative AI feature on Google Search." The help page lists no clicks, click-through rate, position or queries.
• Four dimensions: Pages, Countries, Dates and Devices.
• URL filters work as in the Performance report, so you can reuse your stage groups.

Clicks from AI Overviews and AI Mode are counted, but only inside the main Performance report's Web totals, where they can't be separated from other results. If the report is missing, Google says this "usually happens when your site hasn't received enough impressions in generative AI features." It can also mean the site has been excluded from those features. Our guide to reading the Generative AI performance report goes further.

For Microsoft Copilot and Bing, Bing Webmaster Tools has its own AI Performance report, launched as a public preview in February 2026. Microsoft says a citation there "does not represent traffic, clicks, or user engagement." We found no comparable report for site owners from other AI assistants.

GA4: tag pages by stage with content groups

GA4 has no TOFU, MOFU or BOFU dimension. Google's content groups "let you categorize pages and screens into custom buckets," which is the closest native fit. Using them for funnel stage is our application, not a Google recommendation. Set up one group per stage (Learn, Compare, Decide), or one group per topic plus a second grouping for stage, which Google says needs custom parameters registered as custom dimensions.

Then, as Google puts it, "select the Content group dimension in the Pages and screens report or add the dimension in an exploration." Compare engagement and key events by group. The tag setup itself is in calls to action and forms by funnel stage, so it isn't repeated here.

One limit trips people up. If you link Search Console to GA4, Google says "Search Console metrics are only compatible with Search Console dimensions and the following Analytics dimensions: Landing page, Device, Country." Content groups won't combine with Search Console clicks. Use landing page lists for that view.

Key events and leads by topic

Leads are the outcome that matters, so count them precisely. The setup is covered in the forms article linked above: a generate_lead event on each successful form, marked as a key event, with later lead stages sent from your CRM. For reporting, three habits matter:

1. Keep different actions apart. Track phone taps, booking clicks and downloads as separate events, so a checklist download isn't counted as a quote request.
2. Record the topic of each lead: the article or service the inquiry came from, or what the person asked about. On one clinic, leads were tracked by condition. While numbers are small, topics are easier to compare than single pages.
3. Report qualified leads next to raw leads when your CRM sends them, so a stage that brings many poor-fit inquiries doesn't look better than it is.

Set events up before launch: Google says marking an event as a key event "doesn't change historic data."

Attribution: how TOFU pages get credit

A reader may find a TOFU article in March and fill in a form in May. Whether the article gets credit depends on attribution settings.

• GA4 offers three models: data-driven, paid and organic last click, and Google paid channels last click. First click, linear, time decay and position-based are "no longer available as of November 2023."
• For most key events the default lookback window is 90 days.
• Google says all models "exclude direct visits from receiving attribution credit, unless the path to key event consists entirely of direct visits."
• The Conversion attribution analysis report, added January 16, 2026 to the advertising workspace, includes a view that "categorizes touchpoints into Early, Mid, and Late stages." Google marks it Beta and says it "may not be available to your Google Analytics property."
• A path exploration can work backward from a key event to show which pages came before it.

Explorations look back only as far as your data retention setting. The default is 2 months; standard properties can keep 14. Change it before launch.

AI assistants: what GA4 can and can't count

Since May 13, 2026, GA4 has an AI Assistant default channel. Google describes it as the channel for visits "from sources like ChatGPT, Gemini, Deepseek, Copilot, or Grok," and adds: "It excludes Google's AI Overviews and AI Mode." Those visits count as Organic Search. The channel is assigned when the referrer matches a list of assistants that Google doesn't publish. A visit that arrives with no referrer and no campaign tags is counted as Direct. Treat the channel as a floor, not a total. Our article on the AI Assistant channel in GA4 covers what it misses.

What a monthly report shows

A monthly guide report should fit on a few pages and end with decisions. This structure is house practice:

The AI-specific parts of a report are covered in what a monthly GEO report should include.

What not to conclude

• Search Console and GA4 won't match. Google lists reasons including privacy, processing, time lag, time zones and JavaScript.
• Small numbers swing. A BOFU page with three leads one month and one the next hasn't necessarily declined.
• No AI report is complete. Google's report counts impressions only; GA4's channel depends on referrers.
• No fixed ratio of articles to leads exists. Anyone promising a number of leads from a number of articles is selling something they can't deliver.

When to start judging a new guide is covered in the first 90 days after launch.

Conclusion

Measuring a funnel guide comes down to labeling pages by stage and reading each stage against its own job: Search Console page groups for visibility, the Generative AI report for impressions in AI Overviews and AI Mode, GA4 content groups for reader movement, and key events with topic tags for leads. The tools are partial, so the report should say what each number can and can't show. Measurement by stage is step nine of our TOFU, MOFU, BOFU content strategy, and performance tracking is part of our content marketing services. More guides are in our GEO and AEO Guide.
