Free Keyword Research: The Complete Workflow (No Paid Tools)

You don’t need a ₹15,000/month tool to do serious keyword research. Google itself gives away more keyword intelligence than any paid tool contains — autocomplete, People Also Ask, Search Console, Keyword Planner. This lesson turns those free sources into one repeatable workflow.

In Lesson 2.1 you learned to read the goal behind a query. Now we collect queries at scale. The workflow has five steps, and we’ll run a real example through all five — a home baker in Pune who sells customised cakes — so you see exactly what the output looks like at each stage.

Step 1: Build Your Seed List

Seeds are the raw topics everything else grows from. Open a spreadsheet and answer four questions in your customers’ language, not your industry’s language:

• What do you sell or teach? (products, services, topics)
• What problems do you solve? (the situations that make someone search)
• What would a complete beginner type? (they don’t know your jargon)
• What do customers actually ask you? (WhatsApp messages, calls and shop conversations are keyword gold)

Aim for 10–20 seeds. Don’t judge them yet — expansion comes next.

Step 2: Expand With Google’s Own Suggestions

Google’s suggestion features are not guesses — they are built from real queries people actually type. That makes them the most honest keyword source in existence.

2a. Autocomplete

Type each seed into Google slowly and record every suggestion that drops down. Then multiply the seed systematically:

• Seed + each letter: “eggless cake a…”, “eggless cake b…”, “eggless cake c…” — each letter reveals a new set of suggestions.
• Question prefixes: “how eggless cake…”, “why eggless cake…”, “which eggless cake…”
• Word order flip: “cake eggless…” sometimes surfaces different completions.

2b. People Also Ask (PAA)

Search each seed and expand the PAA boxes. Every question you click loads more questions — three or four clicks deep gives you a question tree. These map directly to informational content: blog posts, FAQ sections, and (as you saw in Lesson 1.4) featured snippet and AI citation opportunities.

2c. Related Searches

Scroll to the bottom of the SERP. The related searches block shows how Google connects your topic to neighbouring topics — often revealing angles you never considered.

Step 3: Mine Google Search Console (Your Private Goldmine)

If your site has been live even a few months, Google Search Console’s Performance report lists the actual queries your site appeared for — real data no paid tool can see, because it’s your data. Two filters produce instant wins:

• High impressions + low clicks: Google is already showing you for these queries; you’re just not compelling or not high enough. These are your fastest improvement targets.
• Position 8–20 queries: Pages ranking just off the first page or low on it. A content refresh or better internal linking (Module 3) can push these into meaningful traffic — far easier than ranking a new page from zero.

Export these queries into your sheet and mark them “GSC” — they get priority, because Google has already voted that you’re relevant for them.

Step 4: Validate Volumes With Keyword Planner

Google Keyword Planner lives inside Google Ads (free account, no ads required — skip campaign creation and head to Tools → Keyword Planner). Paste your keyword list into “Get search volume and forecasts”. Without running ads you’ll see volume ranges (like 100–1K, 1K–10K) instead of exact numbers — and that’s perfectly fine, because you’re using it for two decisions only:

1. Kill the zeros: keywords with no measurable volume get deprioritised (though see the long-tail caveat below).
2. Sort the rest into tiers: high / medium / low. Precision doesn’t matter; relative size does.

Keyword Planner’s “Discover new keywords” mode also works as one more expansion source — feed it your seeds and your competitor’s homepage URL, and it suggests related terms with volumes attached.

Step 5: Label Intent and Prioritise

Final step: apply Lesson 2.1. Every keyword in the sheet gets an intent label — I / N / C / T — decided by a quick SERP check for anything ambiguous. Then score priority with three simple columns:

Your first targets are High relevance + any volume + Possible/Easy winnability. This simple triage beats any tool’s “keyword difficulty” score, because it’s grounded in what you actually saw on the SERP.

How Often to Repeat This

Keyword research isn’t a one-time event. A practical rhythm:

• Full workflow: once per quarter, or when entering a new topic/service area.
• GSC mining (Step 3): monthly — it’s ten minutes and it compounds as your site grows.
• PAA harvesting: every time you write, check the PAA for that lesson’s topic — fresh questions appear constantly.
