SaaS Keyword Research: A 2026 Guide to Buyer Keywords

SaaS keyword research finds the searches your future customers type before they buy software, then decides which ones deserve a page. Start from customer language in sales calls, support tickets, G2 reviews and onboarding surveys. Check demand in Ahrefs or Semrush, and score each term on product fit, intent, winnability and proof before it reaches the calendar.

Most keyword lists fail at that last step. Tools sort by volume, and volume rewards broad terms your product can't win or can't answer. A 350-search keyword your sales team hears every week will usually beat a 5,000-search term that mostly brings students.

We wrote this as the research chapter of our SEO for SaaS hub. It's for teams who already know what SEO is and want a keyword list their sales team would recognize.

What Is SaaS Keyword Research?

SaaS keyword research finds the search terms that lead to trials and demos for a software product. It differs from generic keyword research in two ways. The buyer is often a committee rather than one person, and a keyword with 40 monthly searches can sit in front of a five-figure annual contract.

B2B keyword research follows the same logic for any company that sells to other businesses. The difference with software is the product itself. People search for its integrations, its error messages, templates for the job it does and alternatives to it, so the product creates keywords a consulting firm never sees.

The Four-Signal Keyword Score

The Four-Signal Keyword Score is how we decide whether a keyword earns a page. Rate each term from 0 to 3 on product fit, buyer intent, winnability and customer proof, then add the four numbers. Terms scoring 9 or more get built this quarter, terms scoring 6 to 8 wait in the queue, and anything lower gets cut.

Product fit works as a gate. A 0 on fit means no page, whatever the other three say, because traffic you can't convert costs writing time and pulls the cluster off topic. Ranking for "what is CRM" when you sell email marketing software brings visitors who'll never buy.

Winnability is where most teams misjudge. Ahrefs builds its keyword difficulty score from how many websites link to the top 10 ranking pages, so compare those pages with your own site rather than trusting the number alone. As a rule of thumb, if two or more page-one results come from sites within 15 DR points of yours and have fewer than 20 referring domains, score winnability a 2 or 3.

The gap between head terms and SaaS terms is wide. When we checked in September 2026, every organic top 10 result for "keyword research" (618,000 US searches, KD 88) came from a domain rated DR 84 to 100. For "saas keyword research" (350 searches, KD 3), a DR 26 site ranked second with two referring domains.

Picking the winnable version pays off fast. In a SAASY LINKS niche edit campaign for an HR tech SaaS, 12 contextual placements averaging DR 55 moved the target page from position 31 to position 8 for "best HR software for startups" within 30 days. The head term "HR software" would have needed years.

Where Do SaaS Keywords Come From?

The best SaaS keywords come from customers before they come from a tool. Sales calls, support tickets, G2 reviews and onboarding surveys show the words buyers use for their problem. That includes phrases that show zero volume in Ahrefs but convert, because they describe a job someone is paying to get done.

Sales calls and demo notes

Search 20 recent call transcripts in Gong, Chorus or your own notes for phrases like "we're currently using", "we tried" and "switching from". Each competitor name that comes up is a candidate for a vs page or an alternatives page. The way prospects describe the problem in the first five minutes is your problem-page keyword list.

Support tickets and help-center search

Export the last 90 days of tickets from Zendesk or Intercom and group them by tag. How-to questions and error messages map straight to docs and help articles, which rank for long, specific queries with almost no competition. Your help center's own search log shows what visitors couldn't find.

G2 and Capterra reviews

Read the reviews for your product and your two closest competitors, focusing on the answers about what problem the product solves. Reviewers name features, integrations and the tool they replaced. And they write the way buyers talk, which marketing copy rarely does.

Onboarding surveys

Add one question to your signup or onboarding flow: "What did you search for before you found us?" After a few hundred answers you'll have the exact phrases that brought in paying users. It's the cheapest keyword research you'll ever run.

Only then open a keyword tool. Paste the phrases in, check which ones carry measurable demand, and group the variants that share a parent topic. The tool's job is to size the list. It shouldn't be the thing that creates it.

SaaS Keyword Patterns Worth Mapping in 2026

Most SaaS keywords fall into a handful of repeatable patterns, and each pattern needs its own page type. Map the pattern before you brief a writer. A comparison search needs a comparison page and an integration search needs an integration page, whatever the volume column says.

The buying-stage patterns (alternatives, vs and pricing) deserve their own playbook, so we won't repeat it here. Our guide to high intent keywords covers how to find them and which to build first.

Build those early. SAASY LINKS' analysis of 90 SaaS content marketing campaigns found that bottom-of-funnel content like comparison and alternatives pages converts at 4.7x the rate of top-of-funnel blog posts.

The pattern also decides how exposed a page is to AI answers. Luke Harsel's Semrush study of 600,000+ keywords found the share of commercial SERPs showing an AI Overview grew 71% between November 2025 and April 2026, while transactional SERPs with an AI Overview fell 5%. "Best tool for X" pages now compete with a summary above them, so they need answers an AI Overview can quote.

How to Do SaaS Keyword Research in Ahrefs or Semrush

Do the tool work in four passes: seed terms from customer language, a competitor gap, filters that strip out junk, and a shortlist scored on the four signals. Each pass takes an hour or two for one product line. The output is a spreadsheet of 30 to 80 keywords, not 3,000.

Seed with customer phrases

Paste 20 to 30 phrases from your customer research into Ahrefs Keywords Explorer or the Semrush Keyword Magic Tool. Open the matching terms and related terms reports for each, and note the parent topic. Keywords that share a parent topic can usually share a page.

Run a competitor gap

Use Ahrefs Competitive Analysis or the Semrush Keyword Gap tool with the two to four competitors your sales team actually loses deals to. Leave out the category giants. HubSpot ranks for thousands of terms you'll never win, and copying its keyword list tells you about HubSpot's product fit, not yours.

Filter the export

Cut anything with "jobs", "salary", "course" or "free download" in it, plus definitions your product can't answer better than Wikipedia. Keep competitor brand terms only if you'll build a vs or alternatives page for them. But keep zero-volume phrases that also appeared in your customer research, because the tool is the less reliable of the two sources.

Score the shortlist

Add four columns for the signals and a total. Score product fit and customer proof first, since they're the fastest to judge and they'll knock out a third of the list. Then check intent and winnability by opening the live search results for each survivor, because the page types ranking there tell you more than any intent label in a tool.

Zero-Volume Keywords: When Should You Build the Page Anyway?

Build a zero-volume page when customer proof is strong and the page would help close deals. Keyword tools estimate volume from samples of search data, so niche B2B terms often show 0 or 10 searches even when your sales team hears them weekly. Treat the number as a floor. It isn't a verdict.

Search Console settles the question after launch. Its Performance report lists the actual queries that showed your page and how many clicks each one earned, and new pages often pick up impressions for variants no tool listed. Check it 60 days after publishing and fold the new phrases into the page.

We'd rather have a comparison page that 30 qualified buyers read each month than a glossary post with 3,000 visitors. Because the 30 are the ones who book demos.

Keyword Research for AI Search and ChatGPT Prompts in 2026

In 2026, keyword research also has to cover the prompts buyers type into ChatGPT, Perplexity, Claude and Google's AI Mode. Prompts run longer than keywords and name constraints like team size or budget. Collect them the way you collect keywords, from sales calls first, then test them in each tool.

Test every prompt more than once. Rand Fishkin and Patrick O'Donnell ran 2,961 prompts across ChatGPT, Claude and Google AI Overviews and found the tools returned the same brand list less than 1% of the time. Track how often your brand appears across 10 runs of each prompt, not where it appeared in one.

Keyword work feeds AI visibility directly. The OppAlerts study of about 167,000 domains found topical relevance on the homepage, measured by keyword alignment, was the second-strongest AI visibility signal at +0.204. A homepage that names your category and core use cases in plain words helps both channels.

What doesn't work is pasting prompt phrases into existing pages. AI models weigh answer quality and source authority, not keyword density, so a page needs a direct answer to the question behind the prompt. Our LLM optimization guide covers how pages get picked as sources.

B2B Keyword Research by Sales Motion and Company Stage

B2B keyword research changes with how you sell. Product-led companies need keywords that lead to a signup in one session, like templates and how-to terms tied to the product. Sales-led companies with contracts above $25,000 a year need fewer, narrower terms that reach evaluators and the people who sign off on budget.

Buying stage is the other axis. Our B2B SEO strategy guide sorts keywords by stage, from problem-aware to ready to buy, and shows which page each stage needs.

For a small team, 30 well-scored keywords with pages behind them beat a 2,000-row spreadsheet nobody opens. Our SaaS SEO services start with that kind of shortlist.

SaaS Keyword Research Tools Compared

You need one paid keyword tool and two free sources. Ahrefs or Semrush covers volume, difficulty and competitor gaps. Google Search Console and your own customer conversations cover what those tools miss, and everything else is optional until your list passes 200 keywords.

Once the shortlist exists, group it into clusters with a hub page each, which our SEO content strategy guide walks through. If you'd rather hand off the research and the writing, our SaaS content agency builds keyword lists from customer calls before a single brief goes out.

What Doesn't Work in SaaS Keyword Research

The failures share a cause: picking keywords because a tool made them look big. Targeting terms your product can't solve, chasing head terms against DR 90 sites, copying a competitor's export and buying ranking guarantees all produce reports that look busy while signups stay flat.

Head terms are the slowest trap. Building 20 links to a "what is SEO" style post won't move it past Moz and HubSpot, and the few visitors it does win aren't shopping. Link budgets go further on commercial pages where page one is beatable.

In our view, an agency promising page one for 50 keywords is the biggest red flag in SEO sales. Those guarantees get met with long-tail phrases nobody searches for. Rankings without traffic or pipeline next to them mean nothing.
