    Why Last-Click Attribution Fails UK Service Businesses

    Every UK service business we speak to knows something is off with their reporting. Google Ads says the cost per lead is £42. The owner is confident it's closer to £120. Both are looking at real numbers — they're just looking through different windows.

    The window most agencies use is last-click attribution. It's cheap, it's easy, and it will slowly steer you into the wrong decisions.

    What last-click actually assumes

    Last-click gives 100% of the credit for a lead to the final channel touched before enquiry. That model implicitly assumes:

    • Every lead has one touchpoint (they don't)
    • The last touch created the demand (it usually just captured it)
    • Channels that never convert have no value (they routinely start the journey)

    For a UK service business, the average enquiry involves 3–6 touches spread across search, Local Pack, reviews, retargeting, and a direct visit. Last-click compresses all of that into a single credit line.

    The three ways it costs you money

    1. It rewards your branded search unfairly. A branded Google Ads click is almost always last. That doesn't mean it caused the lead — it means the customer knew your name already. Cut it and enquiries barely move. Last-click never tells you that.

    2. It punishes SEO and Local. Organic search and Google Business Profile are usually the first touch. Last-click hands the sale to the final paid click. Six months later, the SEO retainer looks unprofitable and gets cancelled. Then paid performance collapses, because the top of the funnel is gone.

    3. It hides phone enquiries entirely. If a customer sees an ad, then rings you 24 hours later from your Google Business Profile, last-click on your website will simply never see that lead. It goes into "direct" or, worse, nowhere at all.

    What to use instead

    You don't need a maths PhD. For a UK service business, a workable model has three ingredients:

    • Time-decayed credit across touchpoints — the closer to enquiry, the more credit, but never zero for the first touch.
    • All channels included, including calls and Google Business Profile actions, not just website events.
    • A blended cost-per-enquiry run over 30-, 60- and 90-day windows — because your buying cycle isn't 24 hours.

    That's the model Dashient's Reporting Dashboard applies out of the box. It won't tell you the "one true channel." That's the point — there isn't one.

    The one-question test

    Ask your current reporting: "What percentage of my enquiries had more than one marketing touchpoint before contacting us?"

    If the answer is "we don't know," you're on last-click. If the answer is "about 60–80%," you're on a real attribution model — and every pound you're about to spend will land better because of it.
