I’ll admit it: I’m rubbish at DIY. I actually have no idea what I’m doing and there’s nothing worse than that sinking feeling you get when you notice a crack in the furniture, or a dent in the wall or a leak.
To hammer home the point, I was tasked last weekend with fixing a loose bathroom tap. I went out to my local DIY shop and was overwhelmed. What I needed (I later learned) was a 15mm spanner. What I purchased was a starter kit that was 10x more expensive and included a whole load of stuff I didn’t need.
Technically, I’d reached the solution because it included the wrench I needed, but I’d spent £50 to fix a £5 problem. I didn’t need more tools, I needed the right one.
PPC (pay-per-click) digital marketing is much the same in B2B. One of the biggest misconceptions is that PPC success comes from reaching more people. More clicks, more impressions, more traffic, it all sounds great (and makes for some wonderful updates). But in complex B2B sectors, particularly technical industries like energy and utilities, bigger rarely means better.
When PPC works in B2B, it really works. The right search strategy can put your business right in front of decision makers at the exact moment they’re looking for a solution. But when PPC goes wrong? It burns budget fast, floods your CRM with poor quality leads and leaves sales teams wondering why enquiries never convert. In reality, great B2B PPC is about precision. It’s about understanding your audience deeply enough to know who not to target.
Recently, we delivered a Google Search Ads campaign for our amazing clients Wattstor, generating 92 marketing qualified leads with a cost per lead of £261.57 in an incredibly specialist market. The success of the campaign didn’t come from broad targeting or massive keyword lists. It came from careful optimisation, technical audience understanding and disciplined targeting.
Here are five of the biggest B2B PPC mistakes we see businesses making, and how to avoid them.
This is probably the most common issue in B2B PPC. Businesses often build campaigns around broad industry keywords because they want scale. The problem? Broad targeting usually attracts broad intent. That means your ads start appearing for people who were never going to buy from you in the first place.
In technical sectors, this gets even more complicated. Take battery energy storage solutions (BESS), for example. Searches for commercial-scale BESS infrastructure can overlap heavily with residential solar and home battery searches. If you don’t tightly control targeting, your budget quickly disappears into irrelevant clicks.
In our campaign for Wattstor, audience control became a core strategic focus from day one. Rather than chasing huge keyword coverage, we concentrated spend around high-intent commercial search terms like:
The result? Fewer wasted clicks and significantly stronger lead quality. The lesson here is simple: in B2B PPC, relevance beats reach every time.
Not every keyword means the same thing. Two users might google similar phrases but have completely different goals. One might be researching, another might be comparing suppliers and another might just be looking for a definition. So, understanding intent is everything.
Too many campaigns are built around keyword volume rather than buyer behaviour, but high search volume doesn’t automatically mean high commercial value.
Carrying out intent analysis helps you understand what the buyer is actually looking for, whether the search suggests commercial or informational intent, how close that user is to a buying decision and whether the keyword aligns to the audience intent.
This is particularly important for B2B sectors where terminology overlaps across industries or audiences.
If your keywords don’t align with genuine buying intent, you’ll spend money attracting people who were never likely to convert.
Negative keywords are one of the most underrated parts of PPC strategy, but they’re often the best thing to protect your budget.
In our example BESS campaign, one of the biggest ongoing challenges was filtering out domestic traffic. Residential searches continuously crept into search term reports, despite careful targeting.
Rather than switching everything to exact match and limiting the campaign’s scale, we used a more balanced optimisation approach – weekly search term reviews, continuous negative keyword additions, hybrid phrase and exact match structures, and ongoing bid refinement based on commercial intent.
That optimisation discipline made a huge difference over time. B2B PPC shouldn’t just focus on who you want to target, it also needs a clear strategy for who you absolutely don’t want clicking your ads.
Without that filtering process, platforms like Google will happily spend your budget on low-value traffic.
Even great PPC campaigns fail when the landing experience doesn’t match the search intent, and this is where many businesses lose momentum. A user clicks an ad expecting a specific solution, then lands on a generic homepage packed with competing messages, unclear navigation and no obvious next step. Conversion rates immediately suffer.
For the Wattstor campaign, we created a dedicated landing page specifically designed around campaign traffic and search intent. Every part of the experience aligned with the keywords and ad messaging:
That consistency matters because the strongest PPC campaigns create a seamless journey from search term, to ad copy, to landing page, to conversion. If those elements feel disconnected, users lose confidence quickly.
One of the fastest ways to waste PPC budget is assuming campaigns can run themselves.
Successful B2B PPC requires continuous optimisation. That’s because search behaviour, competitor activity, cost-per-click and audience intent are all constantly changing. And AI driven search is already starting to influence how people research suppliers and solutions online.
The campaigns that perform best are the ones being actively managed and refined. Performance improvements can come from ongoing optimisation discipline, including search term analysis, match type refinement and audience filtering.
That’s what allows the campaign to generate a steady flow over a long period, rather than short-term spikes followed by declining quality.
As B2B search behaviour evolves, targeting accuracy is becoming even more important. Buyers are more informed, but their journeys are more fragmented and AI-powered search tools are changing how they discover suppliers.
That means PPC success increasingly depends on understanding buyer intent, audience context, technical language and search behaviour. The businesses winning in PPC aren’t necessarily the ones spending the most, they’re the ones targeting precisely.
Good B2B PPC should feel intentional, every keyword should have a purpose and every step should support the buyer journey. Ultimately, successful PPC isn’t about generating more traffic, it’s about generating the right traffic.
