The most common keyword research mistake is starting with a list of keywords and working backwards to intent. The right approach is the reverse: understand what your customers are trying to accomplish when they search, then find the keywords that signal that intent.
Every search query falls into one of three intent categories:
The user wants to understand something, not buy. Low commercial value, high content value.
The user knows where they want to go. Bidding on your own brand is smart here.
The user has high commercial intent. These keywords drive conversions directly.
For performance campaigns, focus 70–80% of your budget on transactional keywords. Informational keywords can work for top-of-funnel lead gen (especially in B2B) but require landing pages built for that intent stage — not product pages.
Highest intent, lowest CPC, highest conversion rate. Always run. Protect your brand from competitors bidding on your name.
Your main growth engine. Broader reach, higher competition. Segment by specificity — broader terms get more volume, specific terms convert better.
Lower volume but dramatically lower CPC and higher conversion rates. Ideal for Smart Bidding because the intent signal is crystal-clear.
High CPC, lower quality scores (you can't use competitor trademarks in ad copy), but valuable for capturing users in comparison mode.

Not every keyword with high volume is worth bidding on. Evaluate keywords across four dimensions before adding them to your account:
| Metric | What to Check | Red Flags |
|---|---|---|
| Search Volume | Monthly searches in your target geo | Under 100/month = micro-niche; over 100k = very competitive |
| Avg. CPC | Expected cost per click (bid range in Keyword Planner) | High CPC with unclear transactional intent = poor ROI |
| Competition | Low / Medium / High (Keyword Planner indicator) | High competition + broad keyword = expensive without focus |
| Commercial Intent | Look at the SERP — are there ads? Are they product/service ads? | No ads = low monetization potential for that keyword |
A keyword with 500 monthly searches and a 5% conversion rate is worth more than a keyword with 50,000 searches and a 0.1% conversion rate. Always estimate potential conversions, not just potential clicks.
Long-tail keywords — phrases with three or more words — are the most underused opportunity in Google Ads. Here's why they outperform generic terms for most advertisers:
| Keyword | Monthly Volume | Avg. CPC | Likely Conv. Rate | Verdict |
|---|---|---|---|---|
| CRM software | 40,000 | €8.50 | 0.8% | Expensive, competitive |
| CRM software for small business | 8,000 | €5.20 | 2.1% | Moderate, better targeting |
| CRM software for small business free trial | 1,200 | €3.10 | 5.4% | Efficient, high intent |
The long-tail keyword costs 63% less per click and converts at 6.75x the rate of the head term. For the same €1,000 budget: the head term buys 117 clicks producing ~0.9 conversions. The long-tail buys 322 clicks producing ~17 conversions.
Run long-tail seed keywords on broad match with Smart Bidding. The algorithm will find additional high-intent variations you'd never have thought to add manually — while your long-tail base keeps the AI anchored to the right intent profile.
Keyword research isn't a one-time task — it's an iterative process. Here's the systematic expansion framework:
Seed keywords: Core terms that describe your product directly ("CRM software," "customer relationship management tool").
Variations: Synonyms, alternate phrasing, industry jargon ("contact management software," "sales pipeline tool," "lead tracking system").
Related terms: Keywords in the same category that your audience also searches ("email marketing software," "sales automation").
Questions: "What is," "how to," "best," "top" — these capture users in research mode who can be converted via free trial offers.
Competitor terms: Competitor brand names + "[competitor] alternative" and "[competitor] vs [you]" queries.
Here's how to run keyword research for a SaaS CRM product targeting small businesses — from zero to a structured keyword list ready to load into Google Ads.
Write every way a customer might describe your product. For a CRM: "CRM software," "customer database," "contact management," "sales pipeline tool," "lead tracker." Aim for 10–20 seeds.
Enter all seeds at once. Filter by your target country. Export all results. Sort by "Competition" (focus on Medium and High — those have commercial intent). Note volume and CPC ranges for budget planning.
Type each seed into Google and note the autocomplete suggestions. Then add letters (a–z) after your seed to surface "CRM software a[utomation]," "CRM software b[est]" etc. Capture all relevant suggestions.
In your existing campaigns (or a competitor's landing page URL in Keyword Planner), identify which competitors appear. Then research those competitor brand names as potential keywords.
Group keywords into thematic clusters: Brand, Generic-Broad, Generic-Long-tail, Feature-Specific, Competitor. Each cluster becomes an ad group (STAG approach). Aim for 5–15 keywords per cluster.
Before launching, add exclusions: "free," "open source," "GitHub," "tutorial," "how to," job titles ("CRM manager jobs"), and irrelevant verticals. This prevents wasted spend from day one.
Once you have your keyword list, organize them by grouping thematically similar keywords into the same ad group. The rule of thumb: if you'd write a different ad for it, it needs its own group.
| Ad Group | Keywords Included | Ad Focus |
|---|---|---|
| CRM-Brand | [yourbrand], [yourbrand] CRM, [yourbrand] pricing | Brand recognition, direct CTA |
| CRM-Generic-Broad | CRM software, customer relationship management, CRM tool | General product benefits |
| CRM-Small-Business | CRM for small business, small business CRM, SMB CRM software | SMB-specific pain points |
| CRM-Free-Trial | CRM free trial, try CRM software, CRM demo | Free trial offer, low commitment |
| CRM-Competitor | [Competitor A] alternative, vs [Competitor B], switch from [Competitor] | Comparison and differentiation |
El error más común en la investigación de keywords es empezar con una lista de términos y trabajar hacia atrás para deducir la intención. El enfoque correcto es el inverso: entiende qué intenta conseguir tu cliente cuando busca, luego encuentra las keywords que señalan esa intención.
El usuario quiere entender algo, no comprar. Bajo valor comercial, alto valor de contenido.
El usuario sabe adónde quiere ir. Pujar por tu propia marca es inteligente aquí.
Alta intención comercial. Estas keywords generan conversiones directamente.
Para campañas de rendimiento, enfoca el 70–80% del presupuesto en keywords transaccionales. Las informacionales pueden funcionar para captación top-of-funnel en B2B, pero requieren landing pages diseñadas para esa etapa — no páginas de producto.
Mayor intención, menor CPC, mayor tasa de conversión. Siempre actívalas. Protege tu marca de competidores que pujen por tu nombre.
Tu principal motor de crecimiento. Mayor alcance, más competencia. Segméntalas por especificidad.
Menor volumen pero CPC significativamente más bajo y mayor tasa de conversión. Ideales para Smart Bidding porque la señal de intención es cristalina.
CPC alto, menor Quality Score, pero valioso para capturar usuarios en modo comparación.
