The hidden cost of poor marketing measurement

When we commissioned our UK research, we almost expected the data to point towards an under-funded, marketing-immature partner landscape. What came back told a very different story, because UK partners are busy, most have a plan, and only one in 250 said they don't spend anything on marketing at all. What they struggle to do, in numbers that should concern all of us, is tell you whether any of it worked.

And from experience, that's how partners lose budget. It's rarely because the marketing wasn't working; far more often, it's because nobody could prove that it was.

We asked partners whether they could measure marketing's contribution to pipeline and revenue. 51.2% said yes, 35.2% said no, and 13.6% said they didn't know. If you're not sure whether you can measure it, you can't, which means 48.8% of UK partners either know they can't connect marketing to revenue or genuinely aren't sure.

Only 47.2% run basic reporting, and 43.6% run attribution. Perhaps most surprising of all, 12.4% told us they have no plans to introduce basic reporting at all, which makes it one of the two activities partners were most likely to rule out entirely. The other was customer case studies. It's a little ironic that the two cheapest things on the list - one proves what you did, the other proves it worked - are the two partners are most willing to write off.

With Co-op moving to reward growth rather than retention, partners are going to be asked to show what their marketing investment delivered - by Microsoft, by their distributor, and by their own board when the numbers get tighter. Reporting has quietly gone from being a nice-to-have to being the thing that protects your funding.

And there's a bigger commercial picture too. On average, UK partners told us marketing they generated themselves accounted for 22.1% of new business, while Microsoft referrals and distributor or vendor leads together brought in 35.1%. If you can't see which of your own activities is producing that 22%, you can't do more of what works or stop what doesn't, so the whole budget stays stuck.

Poor measurement doesn't show up as a line item, which is exactly why it's so easy to ignore. But it costs partners in three very real ways.

One of the most striking findings in the whole report sits right here. 75.6% of business owners said their business can measure marketing's contribution to pipeline, compared with 35.3% of heads of marketing. That forty-point gap is the widest split between the boardroom and the marketers doing the work anywhere in the study.

There's a reasonable explanation, and it isn't that anybody's being dishonest. Owners see the outcome - the pipeline looks alright, deals are closing - and reasonably assume marketing played its part. Heads of marketing see the mechanics, and they know which bits they can actually evidence. But that comfort has a cost, and it tends to land at exactly the wrong moment.

None of this needs an expensive platform or a data team. Firstly, agree what a good lead looks like, in writing, with sales - one paragraph is enough, as long as two people looking at the same enquiry would categorise it the same way. Then record where every enquiry came from, in one place that everyone can access, rather than in an inbox or somebody's head.

Once that's in place, look at your tracking. Automated tracking inside your CRM is the best place to start, and UTM tags can help as a quick fix. Within a few months, you'll have a reliable answer to where the work comes from, and a far stronger footing for your next budget conversation.
