SaaS Keyword Research Guide: Tips To Grow Signups & Bring More Leads

You’ve built a great SaaS product. Now comes the real challenge – finding the right people.

Every day, thousands of potential customers type something into Google. They’re looking for tools, solutions, and answers to problems your product can solve. But if your website doesn’t appear in those search results, they’ll never find you. That’s where SaaS keyword research comes in.

Keyword research is the process of finding the specific words and phrases that your target audience uses when searching online. When you understand those words and use them in your content, your product becomes easier to find – and that means more signups, more trials, and more growth.

This guide explains everything you need to know: what SaaS keyword research is, why it’s different from regular keyword research, how to do it step by step, and how to turn your keyword list into real results.

What Is SaaS Keyword Research?

SaaS keyword research is the process of finding search terms that your ideal customers type into Google or another search engine. But it’s not just about choosing popular terms – it’s about finding the right words that match what your product does and what your customers really want.

Think of it this way: Someone searching for “what is project management” is simply curious. Someone searching for “best project management software for remote teams” is ready to explore options and possibly buy. These two searches may appear similar on the surface, but they signal very different levels of purchase intent.

For SaaS companies, this distinction is very important. Your keywords need to connect to a specific problem that your software solves – not just to drive random traffic.

Why SaaS Keyword Research Is Different

Keyword research for SaaS is not the same as doing it for a clothing brand or a local restaurant. SaaS buyers think, search, and make decisions differently – and your keyword strategy needs to reflect that. 

Here’s what makes SaaS keyword research unique:

Buyers search in teams. Software purchases often involve multiple people – the person who uses it every day, the IT team who sets it up, and the executive who approves the budget. Each person searches with different questions. A developer searches for “API documentation and integrations.” A manager searches for “reporting dashboard features.” An executive searches for “ROI of project management software.” Your keyword research should cover all of these perspectives.

Integration and compatibility searches are common. SaaS buyers already use other tools and want to know if your product works with them. Searches like “CRM that integrates with Slack” or “email tool that integrates with HubSpot” are highly targeted and very specific.

Comparative searches show strong purchase intent. When someone searches for “best alternative for [tool name]” or “[product A] vs. [product B],” they are actively evaluating options. These are called bottom-of-funnel keywords, and they are extremely valuable for SaaS companies. 

Compliance and trust terms are important. Searches with terms like “SOC 2 compliant,” “HIPAA-ready,” or “data residency options” indicate that the buyer is concerned about security and compliance. These are real objections that show up in the sales process – and they are also relevant in your keyword research.

The 3 Types of SaaS Keywords You Need to Know

Before you start building your keyword list, understand the three main keyword types based on where a person is in their buying journey. These are called TOFU, MOFU, and BOFU.

BOFU (Bottom of Funnel) – Buy Now Keywords

These are the most valuable keywords for SaaS growth. People who search for these terms are actively looking to buy or sign up. Examples include “[product] free trial,” “best [category] software,” “[product] vs. [competitor],” and “[product] pricing.” If you’re just starting your SEO efforts, prioritize these first. They drive revenue and also signal to search engines what your product does.

MOFU (Middle of Funnel) – Problem-Solving

Keywords These keywords are typed in by people who have a pain point and are looking for ways to fix it. For example, “How to reduce customer churn” or “The best way to automate sales reporting.” A great strategy here is to write a helpful guide that addresses the problem, then naturally show how your tool makes the solution faster and easier. 

TOFU (Top of Funnel) – Awareness Keywords

These are broad informational searches like “what is CRM software” or “how does email automation work.” They attract a large number of visitors but most of them are not ready to buy. Focus on TOFU keywords only after you have covered your BOFU and MOFU ground. They are very competitive and have very little business value for early-stage SEO.

What to Do Before You Start Keyword Research

Good keyword research doesn’t start with a tool. It starts with understanding your customers and your market. Here’s what to prepare before you start searching for a single keyword:

Know your customer. Create simple user personas that describe who uses your product, what their job is, what problems they face, and how they talk about those problems. This will shape every keyword decision you make.

Read your reviews and support chats. Your existing customers use real language to describe the value of your product. Mining reviews, testimonials, support tickets, and sales call transcripts gives you the exact phrases used by real buyers-phrases that often make great keywords.

Analyze your competitors. See what keywords your top competitors rank for. You’ll get two things: A list of proven keywords where competitors don’t cover specific topics. Those gaps are golden opportunities for Santhya Infotech and any other growing SaaS brand.

Study the market. Read industry reports, check popular blogs, and see what content is trending in your niche. This gives you an idea of ​​what topics your audience is currently interested in.

Step-by-Step: How to Do SaaS Keyword Research

Now that you are prepared, here is how to actually find and build your keyword list.

Step 1: Build a Seed Keyword List

Start by writing down broad, simple words that describe your product and the problems it solves. These are called seed keywords. For example, if your SaaS is an invoicing tool, your seeds might include: invoicing, billing, payment tracking, small business finance, and online invoice generator.

Don’t overthink this step. Cast a wide net and write down everything that comes to mind. The goal here is quantity. You’ll refine and filter later. Think about your customers’ job titles, industry vocabulary, the integrations they care about, and what tasks your tool helps them complete.

Step 2: Expand Your Seeds Into Real Keywords

Take each seed keyword and expand it using keyword research tools like Ahrefs, SEMrush, Ubersuggest, or Google Keyword Planner. These tools show you related search terms, their monthly search volume, and how difficult it is to rank for them.

For each seed, create keyword variations that reflect different stages of the buyer journey. From the seed “Invoicing,” you can expand to “Invoicing Software for Freelancers,” “How to Send Professional Invoices,” “Best Invoicing Tool for Small Business,” and “Free Online Invoice Generator.”

Pay special attention to long-tail keywords – those that contain four or more words. They attract fewer searches per month, but the people searching for them are more specific in what they want. They convert better and face less competition.

Step 3: Group Keywords by User Intent

Not all keywords deserve the same type of content. Once you have your list, sort each keyword by what the searcher is actually looking to do:

• Informational intent – ​​They want to learn something. Best answered with blog posts, guides, or how-to articles.
• Commercial intent – ​​They are comparing options. Best answered with comparison pages, “best of” lists, or case studies.
• Actionable intent – ​​They are ready to take action. Best answered with product pages, pricing pages, or free trial landing pages.

Mapping intent to content type turns keyword research into an actual strategy. For example, at Santhya Infotech, aligning content with the right intent at the right stage of the buyer journey is one of the fastest ways to improve conversion rates from organic traffic.

Step 4: Check Keyword Difficulty and Search Volume

A keyword is only worth targeting if you have a real chance of ranking for it. Tools like Ahrefs and SEMrush give each keyword a difficulty score. For new SaaS websites, focus on keywords with low difficulty scores – even if they have low search volume. Ranking for ten less competitive keywords beats failing to rank for one highly competitive term.

See also search volume. A keyword with 50 monthly searches may still be worth targeting if the searcher’s intent is very commercial. Focus on business value, not just numbers.

Step 5: Group Keywords Into Topic Clusters

Instead of targeting one keyword per page, group related keywords into clusters. A cluster is a set of keywords that all relate to the same broad topic. You create a main “pillar” page that broadly covers the topic, then support it with shorter blog posts that go into more depth on specific subtopics. 

For example, a pillar page might target “Project Management Software for Teams.” Supporting posts might cover “How to Set Up a Project Roadmap,” “Compare Team Collaboration Tools,” and “Agile Project Management Best Practices.” These supporting posts link back to the main pillar page, which tells search engines that your site is a comprehensive, trusted resource on the topic-all of which boosts your rankings for related keywords.

Common SaaS Keyword Research Mistakes to Avoid

Even experienced teams fall into this trap. Beware of them:

Chasing search volume instead of intent. A keyword with 100,000 monthly searches means nothing if those searchers aren’t even remotely interested in your product. Always check intent before adding keywords to your list.

Ignore comparison and competitor keywords. Many SaaS teams avoid targeting keywords that contain competitor brand names. But searches like “best alternative to [competitor]” and “competitor vs. [your product]” are among the highest converting queries in the SaaS funnel.

Skipping BOFU keywords early on. New SaaS brands often want to write broad educational content first. That’s a mistake. Start with keywords that are close to purchase intent. Build authority where it drives direct signups before expanding into awareness content.

Never update your keyword list. The SaaS market moves quickly. New tools launch, trends change, and consumer language evolves. Review and refresh your keyword strategy at least once every quarter to stay relevant and competitive.

How to Turn Your Keywords Into Content That Converts

Finding the right keywords is half the battle. The rest is creating content that actually drives signups and leads.

Here’s how to do it:

Write content that fully answers the question behind the keyword. If someone searches for “how to improve onboarding for SaaS users,” they want a practical, complete answer – not a teaser followed by a sales pitch. Give them real value first.

Make sure there’s a clear next step on every page. An informative blog post should end with a link to a related product feature, free trial offer, or relevant case study. Guide the reader naturally forward.

Use your keywords in page titles, headers, the first 100 words of your content, and meta descriptions. But never stuff them in a clumsy way – always write for humans first, search engines second.

Track your results regularly. Use Google Search Console to monitor which keywords your pages rank for, how many clicks they get, and how rankings change over time. Use this data to improve poorly performing content and double down on what works.

Conclusion

SaaS keyword research isn’t a one-time task. It’s an ongoing process that connects your product with the people who need it most.

Start by understanding your customers – how they think, what they search for, and where they are in their buying journey. Create a seed list, expand it to specific keywords, sort them by intent, and group them into topic clusters. Focus on BOFU and MOFU keywords first, track your performance, and keep refining over time.

Done right, SaaS keyword research becomes one of the most powerful engines for increasing signups and driving qualified leads – without paying for every click. Teams like Santhya Infotech know that sustainable SEO growth starts with a smart keyword strategy, and this guide gives you everything you need to do it.
