How to Do Keyword Research for Free (2026 Guide)

You don’t need to spend a single penny to find out exactly what your customers are typing into Google. Every method in this guide is one our founder-led team uses at SplashSol before we ever open a paid tool, and it works just as well for a Glasgow joiner as it does for an Edinburgh boutique or a UK-wide online shop. Free keyword research won’t hand you exact search volumes down to the last digit, but it will show you real phrases, real questions, and real intent, which is usually all a small business needs to plan months of content. Here’s the step-by-step process, no subscription required.

Why Free Keyword Research Is Enough for Most Small Businesses

Paid tools like Ahrefs and Semrush earn their keep once you’re managing dozens of pages or competing in a crowded national market. But most of what they show you, search volume estimates, related terms, question phrases, is built from the same public data Google already gives away for free. The proprietary part is the modelling behind the volume numbers, not the underlying keywords themselves.

For a typical Scottish SME, the free layer of keyword research usually turns up more ideas than you’ll have time to write about in a year. The challenge isn’t finding keywords; it’s picking the right handful and matching each one to a page that’s actually built to convert. That’s the process we run through with clients as part of our on-page SEO work, and it’s exactly what this guide walks through, step by step.

If you eventually decide a professional should take this off your plate entirely, it’s worth knowing how much SEO costs in the UK before you compare quotes. But there’s no reason you can’t run the first pass yourself, for free, starting today.

Step 1: Start With Google Autocomplete

Open an incognito or private browser window, so your personal search history doesn’t skew what you see, and type a broad term related to your business into Google, say, “boiler cover” or “wedding photographer Glasgow.” Don’t press enter. Google will show a drop-down of the phrases most commonly searched that begin with what you’ve typed. These aren’t estimates or guesses; they’re real queries pulled straight from what people are searching for right now.

Write down every suggestion, then add a word or a letter and see what changes. Autocomplete is free, instant, and unfiltered by any third-party modelling, it’s Google showing you its own live data, for nothing.

Try the “Alphabet Soup” Method

To pull a fuller list, type your seed keyword followed by each letter of the alphabet in turn: “boiler cover a,” “boiler cover b,” and on through to Z. Each letter surfaces a different set of suggestions you wouldn’t otherwise see. Repeat the exercise with common question words in front of the keyword too, who, what, why, how, can, does, should, and with numbers. Within about ten minutes you’ll have a long, genuinely useful list of phrases worth exploring further.

Step 2: Mine People Also Ask and Related Searches

Search your main keyword and scroll to the “People Also Ask” box that usually appears partway down the results. Every question inside it is one Google already knows people ask around that topic. Click on a question to expand its answer, and Google will load two or three fresh questions underneath, keep clicking and you can often pull ten or fifteen genuine, specific questions from a single search.

Scroll to the very bottom of the results page next and you’ll find “related searches,” another free list of terms Google associates with your query. These are brilliant for spotting angles you hadn’t considered, and they frequently make excellent subheadings or entirely new blog topics in their own right.

Between autocomplete, People Also Ask, and related searches, you can typically build a working list of thirty or forty relevant phrases in under half an hour, without opening a single paid tool or creating an account anywhere.

Step 3: Use Google Trends to Check Demand and Seasonality

Google Trends won’t give you exact monthly search volumes, but it shows you the shape of demand over time, which is often more useful for planning purposes. Type a keyword in and you’ll see a graph of relative interest over the past twelve months, five years, or since 2004. This is invaluable for spotting seasonal patterns: “boiler repair” spikes every winter, “wedding venues Scotland” climbs steadily from January through to June, and “Christmas party ideas” behaves exactly as you’d expect.

Trends also lets you compare two or more terms side by side, which helps when you’re deciding which phrasing to prioritise and two options seem equally sensible on paper. You can filter results by country and even by region, so a Glasgow business can check whether interest in a term is genuinely strong right across Scotland or concentrated somewhere quite different.

Check the “related queries” panel at the bottom of any Trends search too, and look specifically for terms marked “breakout,” an early signal of a topic gaining momentum before it becomes properly competitive.

Step 4: Free Keyword Tools Worth Bookmarking

Beyond Google’s own search results pages, there’s a small stack of free tools that consistently earn their place in a keyword research routine. None of them require a card on file, and each is best suited to a slightly different job, so it’s worth knowing which one to reach for.

Search Console deserves a special mention: if your site has any history at all, its Performance report shows the exact queries already bringing people to you, including ones where you rank on page two or three of Google, frequently the quickest wins available, because you’re improving an existing position rather than starting from nothing. We built our own free keyword density checker and SERP preview tool for exactly this stage of the process, so you can sanity-check a page before it goes anywhere near “publish.” You’ll find the full set on our free tools page.

Step 5: Peek at Your Competitors Without Paying a Penny

You don’t need a paid crawler subscription to see what’s already working for competitors. Search your main keyword and open the top three or four ranking pages. Look at their title tag (the blue link text in the results), their headings, and the questions they’ve bothered to answer, if three separate competitors all cover the same subtopic, that’s a strong hint Google expects it to be there.

Use the site: search operator, for example, site:competitorname.co.uk keyword, to see every page on their site Google has indexed around a topic. This reveals how they’ve structured their content, and whether they’ve split one broad subject into several narrower, more specific pages rather than cramming everything onto one.

Right-click and choose “view page source,” or use your browser’s built-in inspector, to see the meta description and heading structure a competitor has used, without them ever knowing you looked. None of this needs a login, a free trial, or a credit card, it’s all sitting in plain HTML, free for anyone willing to spend two minutes looking properly.

Step 6: Understand Search Intent Before You Write Anything

A keyword list is only half the job. Before you write a single word, work out what someone actually wants when they type that phrase, because Google sorts its results by intent, not simply by keyword match. Broadly, almost every search falls into one of four camps.

Informational searches look like “how to do keyword research for free” or “what is local SEO.” Navigational searches are someone looking for a specific brand or website by name. Commercial searches, such as “best SEO agency Glasgow,” mean someone is comparing options before they buy. Transactional searches, like “hire SEO consultant,” mean someone is ready to act right now.

Check what’s actually ranking for your keyword before you commit to a page type: if the top ten results are all long-form guides, Google has already decided that query is informational, and a bare service page is unlikely to outrank them no matter how well it’s written. Matching content type to search intent is one of the most overlooked parts of on-page optimisation, and it costs nothing to check, just look at what’s already ranking before you start typing.

Step 7: Map Keywords to the Right Pages

Once you’ve got a list of phrases sorted by intent, group them by topic and assign each group to a single page, either one that already exists or a new one you plan to build. Giving two different pages the same primary keyword just splits your own ranking potential and confuses Google about which page it should actually show, a problem known as keyword cannibalisation, and one of the most common reasons an otherwise solid site underperforms.

A simple spreadsheet works well here: one column for the page URL or working title, one for the primary keyword, one for two or three supporting phrases to weave naturally into subheadings, and one noting the search intent you identified in the step above. This becomes your content brief before a single word gets written.

It’s also worth checking that the page you’re mapping a keyword to can actually be found and indexed in the first place, a beautifully targeted page buried behind broken navigation, or accidentally blocked in robots.txt, won’t rank no matter how well-chosen the keyword is. That’s where basic technical SEO checks earn their keep alongside the keyword work itself.

Local Keyword Tips for Scottish and UK Businesses

If you serve a specific area, build location into your research from the very start rather than bolting it on afterwards. Search your core service plus your town or city, “plumber Motherwell,” “seo edinburgh”, and note how the results differ from the generic version of the term; often a completely different set of competitors appears. Check the “near me” version too, since Google now treats “near me” and “in [town]” searches almost identically for most local trades.

Your Google Business Profile carries its own free insights showing the exact search terms that led people to your listing, which is data no paid keyword tool can replicate. For businesses covering more than one location, dedicated city pages tend to outperform a single generic page trying to rank everywhere at once, it’s why we built a standalone Edinburgh SEO page rather than asking our Glasgow page to cover both cities at once. Pair this with a proper local SEO setup and free keyword research goes noticeably further.

If you trade in more than one language, common enough across parts of Scotland and the wider UK, repeat this entire process separately in each language rather than relying on a direct translation. The phrases people actually type rarely match a word-for-word translation of the English term, so treat each language as its own mini research project.

Turning Your Free Research Into a Simple Content Plan

Once your spreadsheet is built, prioritise by a mix of intent and effort: quick wins from Search Console first, since those are pages you’re already close to ranking for, then informational content to build authority, then commercial and transactional pages once you have the traffic to support them. You don’t need forty new pages this month, three or four well-mapped ones, published properly, will beat a long list left half-finished every time.

Free tools can carry you further than the research stage too. Our AI blog title generator can turn a raw keyword into several headline options once you know what you’re writing about, and it costs nothing to try alongside everything above.

If all of this still feels like a lot to take on alongside actually running your business, that’s precisely what we’re here for.
