Measuring SEO and Paid Search Together | Madrid SEO

Measuring SEO and Paid Search Together: Metrics That Survive Scrutiny

In short
  • Decide what counts as a conversion before you look at any dashboard. Most disputes are definition problems.
  • Track calls. In Madrid service sectors the phone is still where the money arrives, and untracked calls make organic look worthless.
  • Cost per enquiry beats return on ad spend for local businesses, because revenue lands offline.
  • Report the same numbers every month, even the ones that got worse.

Reporting is where most SEO and paid search relationships quietly break: not because results are bad, but because nobody agreed what would be counted. This is a measurement setup that holds up to a finance director's questions.

the gap between analytics and the CRM that is normal, not a bug

Step 1: define the conversions

Write down, before anything is configured, which actions count and what each is worth. For a typical Madrid service business that means: form submission, phone call over a minimum duration, WhatsApp or message thread started, direction request, and booking. Assign a rough value to each from your own close rate and average job size. Rough is fine; absent is not.

The minimum call duration matters more than it sounds. Counting every ring as a conversion inflates paid campaigns that generate misdials and wrong numbers.

Step 2: instrument the channels properly

  • Analytics with server-side or consent-aware tagging, configured so organic, paid, direct and referral do not blur into each other.
  • Call tracking with a number that swaps by source, or at minimum a distinct number on the paid landing pages.
  • Search Console connected, for the query-level view that analytics cannot give you.
  • Business Profile insights, exported monthly, since calls and direction requests from the profile never appear in site analytics at all.
  • CRM or a simple enquiry log with the source recorded at intake, which is the only place the offline outcome exists.

Step 3: the metrics worth reporting

MetricAnswersFails when
Enquiries by channelIs anything arriving at allUsed alone: says nothing about quality
Cost per enquiryIs it getting cheaper or dearerChannels have very different lead quality
Qualified rateIs the traffic the right trafficNobody in sales marks the CRM
Cost per customerThe only number the owner cares aboutThe cycle is longer than the reporting period
Assisted conversionsWhether a channel helps others convertTreated as if it were a direct conversion
Impression share of the target clusterWhether the ground is being takenConfused with traffic. It is a leading signal
  1. Enquiries by channel and district. The headline number, split so you can see where growth came from.
  2. Cost per enquiry by channel. Paid is straightforward; for SEO, divide the retainer plus content costs by enquiries attributed to organic. It will look bad in month two and good in month eight, which is the point.
  3. Assisted conversions. How often each channel appears in a path it did not close. This is what stops paid brand campaigns taking credit for organic work.
  4. Visibility, as a diagnostic. Impressions and average position by cluster, tracked from the district, to explain why the enquiry numbers moved.
  5. Close rate by source. The number that occasionally reveals that the cheapest enquiries are also the worst.

Attribution without the arguments

Every attribution model is a point of view, not a measurement. Knowing what each one is biased towards ends most of the argument:

ModelFlattersUse it when
Last clickPaid search and brand termsCycles are short and the budget question is simple
First clickSEO and socialYou are asking what starts demand, not what closes it
Linear or position-basedNothing in particularSeveral channels are genuinely involved
Data-drivenWhatever the data supportsYou have enough conversions for it to mean anything

Pick one, state it in the report, and stop changing it. A channel that looks better under a different model has not actually improved.

Last-click is the default and it systematically over-credits whatever sits at the end of the path - usually branded paid search. Data-driven or position-based models spread the credit more fairly, but no model is true. The practical compromise: pick one model, use it consistently, and check it once a quarter against the enquiry log, which is the only ground truth you have.

Set the lookback window to match your sales cycle. Thirty days for reactive services, ninety for considered purchases. Businesses that leave it at the default and then argue about which channel works are usually arguing about a setting.

“If two channels are each credited with the same enquiry, the problem is not the channels. It is that nobody wrote down which model the report uses.”
Where most SEO and paid search arguments actually come from

What a good monthly report looks like

One page. Enquiries this month against the last three, split by channel and district. Cost per enquiry for each channel. What was delivered. What is planned. One paragraph explaining the biggest movement, up or down, with a cause rather than a shrug. Everything else belongs in an appendix nobody reads unless something looks wrong.

Frequently asked questions

Why does my analytics number never match my sales number?

Because consent banners, ad blockers, cross-device journeys and offline conversions all remove data. Expect a gap of 10-30% and reconcile against the enquiry log rather than trying to close it.

Is return on ad spend the right metric for a local business?

Rarely, because the revenue lands offline days later. Cost per qualified enquiry, plus a close rate you measure yourself, is more honest and easier to act on.

How long before SEO shows up in these numbers?

Should we pause ads once SEO is working?

Rarely, and never on the commercial terms. Ads and organic on the same query usually earn more together than either alone, and pausing removes the fastest signal you have about what converts.

Can we use paid search to test SEO ideas?

Yes, and it is one of the best uses of a small ad budget. A term that does not convert on ads will not convert on organic either, and you learn it in a fortnight instead of six months.

Local Pack effects in four to eight weeks, organic enquiry volume from month three to six. Cost per enquiry for SEO improves for as long as the work continues, which is the whole argument for it.
