SEM Keywords: Stop Bidding on Intent You Already Own

SEM keywords are the search terms you bid on in paid search campaigns to match your ads against what people are actively looking for. Choosing the right ones determines whether your budget captures genuinely new demand or simply pays a premium to intercept people who were already going to find you.

Most brands get this wrong in the same direction. They over-invest in branded and high-intent terms that convert easily, call it performance, and quietly underfund the keyword categories that would actually grow the business. The mechanics of SEM are well-documented. The strategic thinking behind keyword selection is where most teams fall short.

Why Most SEM Keyword Strategies Are Built Backwards

Earlier in my career I was as guilty of this as anyone. Running performance channels, I overvalued lower-funnel conversions and built keyword strategies almost entirely around purchase intent. The results looked excellent. ROAS was strong, cost per acquisition was defensible, and the client was happy. What I didn’t ask often enough was how much of that conversion volume would have happened without the paid click at all.

It’s a question the industry still resists. There’s a version of SEM keyword strategy that amounts to paying to intercept someone who typed your brand name directly into Google. You capture the click, attribute a sale, and report a strong return. The sale was coming regardless. You’ve bought credit for demand that already existed.

This isn’t an argument against bidding on branded terms. There are legitimate reasons to do it, particularly in competitive categories where rivals bid on your brand. But if branded and high-purchase-intent terms make up the majority of your SEM keyword investment, you’re not growing the business through paid search. You’re renting a lane you mostly own anyway.

The brands that use SEM well think about keyword strategy the way a retailer thinks about store layout. Someone who walks to the back of the shop and picks up exactly what they came for was probably going to buy. The real commercial opportunity is the person browsing, comparing, not yet decided. That’s where keyword strategy gets interesting, and where most budgets are underweight.

How to Build a Keyword Architecture That Reflects the Full Funnel

A keyword architecture is the organised structure of all the terms you bid on, grouped by intent, theme, and funnel stage. Without one, campaigns drift. You end up with overlapping ad groups, cannibalised spend, and no clear logic for how budget flows across the purchase experience.

The most practical way to build one is to start from the customer decision process, not from a keyword tool. Ask what someone searches at each stage: when they first recognise a problem, when they’re comparing options, when they’re ready to buy, and when they’re looking for reassurance post-purchase. Each stage produces a different keyword cluster with different commercial value and different bid logic.

At the awareness end, keywords tend to be broad, informational, and low-converting in the short term. “How to reduce warehouse picking errors” or “best practices for supply chain visibility” are not going to drive immediate transactions. But they reach people before a competitor does, and they allow you to shape how someone frames their problem before they’ve decided what kind of solution they need. This is where SEM intersects with brand strategy, and it’s underused.

Mid-funnel category keywords are where I’d argue the real strategic opportunity sits. Terms like “inventory management software” or “3PL provider UK” represent active consideration. The person searching knows what category they’re in. They haven’t chosen a vendor. Your ad, your landing page, and your offer have a genuine chance to influence that decision. These terms are competitive and expensive, but they represent real incremental demand in a way that branded keywords rarely do.

Bottom-funnel keywords, including branded terms and high-specificity product searches, are where you close. They should be in the mix, but they shouldn’t dominate the budget if growth is the goal. If your SEM keyword strategy is mostly bottom-funnel, you’re harvesting demand that other channels created, or that your brand reputation built over years. That’s not a paid search strategy. It’s a tax on organic intent.

If you’re thinking about where SEM keyword strategy fits within a broader go-to-market approach, the Go-To-Market and Growth Strategy hub covers how paid channels should connect to positioning, audience definition, and commercial objectives rather than operating as a standalone performance lever.

Match Types: The Mechanic Most Teams Misuse

Google’s match type system determines how closely a search query needs to match your keyword before your ad is eligible to show. Broad match, phrase match, and exact match each behave differently, and the gap between what you think you’re bidding on and what you’re actually triggering can be significant.

Broad match has expanded considerably in recent years. Google’s algorithm now interprets intent rather than just vocabulary, which means a broad match keyword can trigger searches that look quite different from what you entered. In theory, this surfaces relevant queries you hadn’t anticipated. In practice, it can bleed budget into tangential searches that don’t convert and are hard to spot without regular search term report analysis.

I’ve audited campaigns where broad match was set as the default across the entire account, and the search term reports read like a tour of the internet. Irrelevant categories, competitor brand terms, informational queries with no commercial intent. The headline metrics looked reasonable because the converting terms were pulling the average up. The waste underneath was substantial.

Phrase match offers more control. Your ad shows when the search contains the meaning of your keyword phrase, in roughly the right order. It’s more predictable than broad and less restrictive than exact. For most mid-funnel category terms, phrase match is a reasonable starting point, with exact match reserved for your highest-value, most commercially specific terms where you want maximum control over what you’re paying for.

Exact match is often underused on high-value terms. If you know that a specific search phrase converts at a rate that justifies a premium bid, exact match lets you control that investment precisely. The trade-off is reach. You’ll miss variations you didn’t anticipate. A sensible approach is to run exact match on your proven converters and phrase or broad match on exploratory keyword clusters, then mine the search term reports regularly to move high-performing queries into exact match and add wasted spend to your negative keyword list.

Negative Keywords: The Most Undervalued Part of SEM

If keyword selection is the offensive play in SEM, negative keywords are the defensive one. They tell Google which searches you don’t want your ads to appear for. A well-maintained negative keyword list is one of the clearest indicators of a mature, well-managed paid search account.

Most accounts I’ve reviewed have underdeveloped negative keyword lists. The initial setup includes a few obvious exclusions, and then the list never grows. Meanwhile, broad and phrase match keywords quietly trigger irrelevant queries, spending budget on clicks that have no realistic chance of converting.

Building a strong negative keyword list starts before a campaign launches. Think about the queries that share vocabulary with your target terms but represent completely different intent. If you sell enterprise project management software, you probably don’t want to appear for “free project management software,” “project management software for students,” or “project management software tutorial.” These are structurally similar searches that will trigger broad match and waste budget on audiences that aren’t your buyer.

The ongoing process matters as much as the initial build. Weekly or fortnightly search term report reviews should be a standard part of campaign management. Every irrelevant query that triggered an impression or click is a data point for your negative list. Over six months of disciplined management, a well-maintained negative keyword list can materially improve campaign efficiency without touching bids or budgets.

Negative keywords also serve a structural purpose. They prevent ad groups from cannibalising each other. If you have separate campaigns for different product lines or audience segments, negatives applied at the campaign level ensure that the right ad shows for the right query rather than your own campaigns competing against each other in the auction.

Competitor Keywords: When to Bid and When to Step Back

Bidding on competitor brand names is one of the more contested decisions in SEM strategy. The mechanics are straightforward: you bid on a rival’s brand term, your ad appears when someone searches for them, and you intercept consideration at a moment when someone is already in the market. The strategic question is whether it’s worth it.

The case for competitor bidding is clearest when you have a differentiated offer and a compelling reason for someone to consider switching. If your product is genuinely better on a dimension that matters to the searcher, appearing alongside a competitor’s brand search gives you a chance to make that case. Done well, it’s a legitimate acquisition channel.

The case against is also real. Competitor keywords typically carry lower quality scores because your landing page isn’t about the brand being searched. That pushes up your cost per click relative to the competitor’s own branded terms. Conversion rates tend to be lower because the person was looking for someone else. And the signal you’re sending to the market, that you need to intercept competitor searches to find customers, isn’t always the one you want to send.

My general view is that competitor bidding makes sense as a tactical play in specific circumstances: when a competitor is running aggressive above-the-line activity that’s driving category search volume, when you have a clear and demonstrable advantage you can articulate in ad copy, or when you’re a challenger brand trying to establish consideration in a category dominated by one or two incumbents. It’s a tool, not a strategy.

What it shouldn’t be is a substitute for building the kind of brand awareness that means people search for you directly. The Semrush analysis of growth tactics illustrates how brands that build genuine demand over time tend to outperform those that rely on intercepting existing intent, whether that’s competitor traffic or bottom-funnel branded searches.

How to Use Search Volume and Competition Data Without Being Misled by It

Keyword research tools give you two primary data points for any given term: estimated monthly search volume and some measure of competition or difficulty. Both are useful. Both are also approximations that get misread as precision.

Search volume figures are averages, often smoothed across twelve months, and the methodology varies by tool. A keyword showing 1,000 monthly searches in one platform might show 600 in another. Neither is definitively right. They’re directional signals, not census data. Use them to understand relative scale between keyword options, not to project exact traffic with confidence.

Competition metrics in paid search tools typically reflect the density of advertisers bidding on a term and the average cost per click range. High competition and high CPC generally signal commercial intent, which is useful. But high CPC doesn’t automatically mean high ROI. A term that costs three times as much per click but converts at five times the rate may be your most efficient keyword. The metric you actually care about is cost per acquisition, and that only becomes visible once you’re running.

I’ve seen teams spend weeks in keyword planning tools building elaborate models based on search volume and projected click-through rates before running a single campaign. The output feels rigorous. In practice, the most important keyword data is what comes out of your own account after three months of live traffic. Real search term reports, real conversion data, real quality scores. That’s when you actually know what’s working.

The planning phase should be tight and directional. Choose your keyword clusters, set your architecture, define your match types, build your negative list, and launch. The refinement happens in the data, not in the spreadsheet.

Long-Tail Keywords: The Commercial Case for Specificity

Long-tail keywords are more specific, lower-volume search phrases that sit further from the broad category terms. “Project management software” is a head term. “Project management software for construction companies under 50 employees” is long-tail. The volume is lower. The intent is much clearer.

Long-tail terms tend to have lower competition and lower CPCs because fewer advertisers bother with them. The aggregate volume of long-tail searches across a category is typically substantial, but the individual terms look small enough that many teams don’t prioritise them. That’s the opportunity.

When I was growing a performance agency from a small team to over a hundred people, one of the things that consistently differentiated our work was the depth of our keyword architecture. Competitors were bidding on the obvious terms. We were building out the long-tail clusters that nobody else had bothered with, matching specific ad copy to specific intent, and landing people on pages that spoke directly to what they’d searched. Conversion rates were materially higher and costs were lower. Not because we’d found a secret. Because we’d done the work.

Long-tail keywords also give you better alignment between search intent and landing page content. When someone searches a highly specific phrase, you can write ad copy and build a landing page that addresses that exact context. The relevance signal improves your quality score, which lowers your CPC. The specificity improves conversion because the person arrives somewhere that feels like it was built for them. Both effects compound over time.

The practical challenge with long-tail keywords is scale. Managing hundreds or thousands of specific terms requires either strong automation, disciplined account structure, or both. The answer isn’t to avoid long-tail keywords. It’s to build the infrastructure to manage them properly, whether that’s through smart campaigns with strong negative keyword lists or through carefully organised ad groups with specific match types.

Incrementality: The Question SEM Keyword Strategy Needs to Answer

The most important question in SEM keyword strategy isn’t which keywords drive conversions. It’s which keywords drive conversions that wouldn’t have happened otherwise. That’s incrementality, and it’s the lens through which keyword investment decisions should in the end be made.

Branded keywords are the clearest case for incrementality testing. If you pause branded search spend and organic results still capture most of the traffic, the incremental value of the paid click is low. If a competitor is actively bidding on your brand terms and your paid ad is suppressing theirs, the incrementality calculation changes. The answer depends on your specific market, your organic visibility, and what competitors are doing. It’s not a universal rule. It’s a question worth asking.

The Vidyard analysis of why go-to-market is getting harder touches on a dynamic that’s directly relevant here: as channels become more crowded and attribution models more complex, the gap between reported performance and actual commercial impact widens. SEM is particularly susceptible to this because last-click attribution, which is still common in many accounts, systematically over-credits the final paid search click regardless of what drove the underlying intent.

Incrementality testing in SEM typically involves geo-based holdout experiments, pausing spend in specific regions and comparing conversion rates against matched control markets. It’s not a perfect methodology, but it’s a more honest one than relying on last-click attribution to tell you what’s working. If you’re managing significant SEM budgets and you’ve never run an incrementality test, you don’t actually know what your keyword strategy is delivering.

The broader point is that keyword selection and bid strategy are not just technical decisions. They’re commercial ones. Every pound or dollar allocated to a keyword cluster is a hypothesis about where incremental value exists. Treating it that way, with the discipline of testing and the honesty to act on what the tests show, is what separates SEM strategy from SEM activity.

For more on how paid search fits within a coherent growth framework, the Go-To-Market and Growth Strategy hub covers the strategic scaffolding that makes channel investment decisions more defensible and commercially grounded.

Keyword Strategy in Practice: What Good Account Management Looks Like

When I was judging at the Effie Awards, one of the things that stood out in the entries that won on effectiveness was how clearly the channel strategy connected to a commercial objective. Not “we ran paid search and it drove conversions,” but “we identified a specific audience segment at a specific point in the decision process and built a keyword strategy that reached them before a competitor could.” The specificity of thinking was visible in the results.

Good SEM keyword management has a rhythm. Weekly search term report reviews to catch waste and surface new opportunities. Monthly performance reviews against keyword cluster targets, not just overall account metrics. Quarterly architecture reviews to assess whether the keyword structure still reflects how customers are actually searching, because search behaviour evolves and keyword strategies that aren’t updated drift out of alignment with reality.

Ad copy testing should be tied to keyword clusters. The message that works for a high-intent bottom-funnel term is different from the one that works for a mid-funnel category search. Running the same ad copy across the account is a signal that keyword strategy and creative strategy aren’t talking to each other.

Landing page alignment is often the weakest link. Teams spend time building keyword lists and writing ad copy, then send all traffic to the homepage or a generic product page. The relevance signal drops, quality scores suffer, and conversion rates underperform what the keyword strategy should be capable of delivering. The keyword, the ad, and the landing page need to form a coherent chain. Each one should feel like a natural continuation of the one before it.

The BCG work on brand and go-to-market strategy makes a point that applies directly here: performance channels work best when they operate within a coherent brand and positioning framework rather than as isolated demand-capture mechanisms. SEM keyword strategy is more effective when the brand has done the upstream work of making people want to search for you in the first place.
