Keyword research sounds like something technical, reserved for SEO specialists with expensive tools. In reality it’s simpler and more important than it sounds: understanding exactly what words your potential customer uses when searching for what you offer. Without that, you can write the best content in the world and nobody finds it, because you’re speaking a different vocabulary than your audience.
The good news: you can do this well without spending a dollar on tools.
Step 1: start from real questions, not assumptions
The most common mistake is starting from what you think people search for, instead of what they actually search for. Before opening any tool, do this exercise: write down the 10 questions your customers ask you most often by email, chat, or in person. Those questions, almost word for word, are free keyword research of the highest quality — they reflect real intent, not a guess.
Step 2: Google Autocomplete, the most underrated free tool
Open Google in incognito mode (so your search history doesn’t skew results) and start typing a phrase related to your business, without hitting enter. Google automatically suggests the most common related searches.
Example: type “how to choose a logo” without finishing the sentence, and Google might suggest “how to choose a logo for my business,” “how to choose a professional logo,” “how to choose a logo that won’t date.” Each suggestion is a real search made by real people, with enough volume for Google to surface it.
Repeat this by adding letters of the alphabet after your phrase (“how to choose a logo a…”, “how to choose a logo b…”), a technique known as “alphabet soup,” to pull out variations that don’t show up in the default suggestions.
Step 3: “People also ask” and related searches
When you search any term on Google, a box called “People also ask” appears with related questions that expand when clicked. It’s another free source of real search intent, and it also gives you clues about which questions to answer within the same article to cover the topic more thoroughly.
At the bottom of the results page, there’s also a “Related searches” section — variations and nearby terms people also search for on that topic.
Step 4: Google Keyword Planner (free, even without running ads)
A lot of people don’t know that Google Keyword Planner is free with just a Google Ads account, with no need to launch any paid campaign. It gives you an estimated monthly search volume for a keyword along with related suggestions.
It’s not as precise as paid tools (it groups volume into ranges rather than giving exact figures if you’re not spending on ads), but it’s more than enough to decide which topics to prioritize when you’re starting out.
Step 5: see what your competitors already answer
Search Google for the terms you care about and look at what pages show up in the top results. Not to copy them, but to understand what angle is already covered and where there’s a gap: a question nobody answers well, a more honest take, more concrete examples than what already exists.

How to organize what you find
It’s not enough to pile up a long list of keywords. Organize them by search intent, which usually breaks down into three types:
- Informational: the person wants to learn something (“how to do keyword research,” “what is SEO”). Educational blog posts fit here.
- Comparative or evaluative: the person is comparing options (“best email marketing tool,” “wordpress vs wix”). Honest comparisons work well here.
- Transactional: the person already wants to buy or hire (“web design agency near me,” “small business website price”). This is where content most directly tied to your services should live.
Prioritize covering transactional keywords directly related to what you sell first — they generate business results fastest, even if they have lower search volume than informational ones.
The mistake almost everyone makes when starting out
Chasing extremely high-volume keywords without accounting for competition. “Digital marketing” has huge volume, but thousands of sites with years of accumulated authority are also competing for it — for a new site, that’s a battle you won’t win in months.
It’s far more effective to start with long-tail keywords: more specific, lower individual volume, but with much less competition and clearer search intent. “Digital marketing for small bakeries” has fewer searches than “digital marketing,” but it’s a battle you can actually win, and the person landing there is much closer to becoming a customer.
Start there. High volume comes later, once your site has accumulated authority from winning the smaller battles first.
