This is probably one of the toughest problems we face as marketers. A lot of times, teams will look at a combination of leading quantitative indicators (clicks, conversions, time spent, etc.) and qualitative signals (from buyer interviews, listening to sales calls, etc.), to take a best guess at what’s working and what’s not.
There are lots of problems with this. It’s tough to isolate messaging as the primary driver of these results, and assign quantifiable measures that will clearly indicate improvement if you make changes. Qual feedback takes a lot of time to gather, especially if you want to validate your messaging across a number of buyer personas. A/B testing can help, but you and your GTM team need to be pretty careful not to change anything else (including upper-funnel stuff like ad copy and targeting) that might impact results, which can be paralyzing. Worst of all, while you’re doing all of this, you’re already in-market: the train has left the station and you’re losing opportunity if you’re not sure your message is connecting.
Instead, my recommendation is to validate your messaging before you go to market. (I won’t do too much self-promotion here, but it just so happens we make a Message Testing solution at Momentive, and it’s one of the products we leverage the most internally.) With a message testing solution, you can get a number of messages in front of your target audience — we tend to target a broad array of business buyers — and get real data on which messages resonate across a attributes like overall appeal, uniqueness, and, importantly, desire to learn more (as well as segmentation across buyers if you like). This is the kind of thing that, a few years ago, you’d probably need to engage a research agency to run, but modern survey-based tools like ours have purpose-built methodologies built-in, and you can get a clear signal on your key messages in just a day or two.
We ran one of these recently to test new headline messaging for our Momentive homepage and it paid off in spades. It validated a messaging direction with our target buyers that was different than what internal leadership was advocating for — so we had some data to bring to the table justifying our positioning (see another of my AMA responses on gaining XF alignment on positioning). If we hadn’t tested, there was a strong risk of going to market with a losing message on one of our most important properties. Instead, we were able to go live on Day 1 with a message that we already know will resonate. In fact, two of our test messages performed strongly, so we were able to run an in-market A/B test to find a winner without really risking any traffic to a poor performer.
tl;dr: I recommend using a survey-based solution to test your messaging before you go to market. You’ll get quantifiable information about what works and what doesn’t, aid internal buy-in, and gain a lot of launch day confidence. You will influence other performance KPIs driven by the GTM team, but PMM’s biggest responsibility is ensuring you have messaging that resonates with target buyers.
