How to do keyword research for a blog for free – The 5 step system that helped me rank without paying for a single tool

The first thing most SEO guides tell you is to buy a keyword research tool.

That advice immediately excludes every blogger who just started, has no budget, and still has everything to prove.

Here is the truth : How to do keyword research for a blog for free is not just possible, it’s enough to build a complete content strategy that ranks on Google.

I built my first six months of keyword strategy using nothing but tools I’m about to show you, and zero of them required a subscription or credit card.

This guide sits inside the master blog SEO and traffic growth as a beginner blogger system, the complete framework I use to grow organic traffic consistently without any paid tool dependency.

What follows is the exact five-step free keyword research system I use. Real screenshots have been replaced with real numbers.

Every technique here has been tested on my own blog across multiple niche posts. No theory. No affiliate-driven tool recommendations. Just what actually works.

What keywords should a beginner blog target and why most beginners get this completely backwards

What keywords should a beginner blog target? Specifically: long-tail phrases of three or more words, with 100–1,000 monthly searches, difficulty scores under 30, and clear informational search intent. Broad, high-volume keywords are almost impossible for new blogs to crack. The smaller, more specific keyword is almost always the faster, more profitable choice.

Most beginner bloggers make the same mistake on day one.

They discover keyword research exists. They search for “blogging tips.” They see 40,000 monthly searches. They write the article.

It never ranks.

Here’s the reality that took me too long to learn: a new blog competing for “blogging tips” is the same as a brand-new bakery trying to compete with Starbucks on the same street corner. The budget, authority, and backlinks required to win don’t exist yet.

The three characteristics if a keyword worth targeting on a new blog :

• Three words or more (Long tail) : longer phrases signal specific intent and face dramatically less competition than single or two-word head terms
• 100-1000 monthly searches – enough traffic to matter if you rank, low enough to be winnable
• Difficulty score under 30 – this is the threshold where new domains can realistically compete without years of authority building

The strategy is not to chase traffic. It’s to win in a specific, well-defined lane until you’ve built the authority to compete more broadly.

How many keywords should a beginner blog targets?

Start with 20–30 keywords organized into topic clusters. Each keyword should map to a specific article you plan to write.

Twenty to thirty keywords sounds small. It’s actually the right number.

Every keyword on your list should map to one specific article you’re confident you can write at genuine depth. A keyword without a content plan is just noise.

How to build a notion blog content planner for topical authority shows the exact system for organizing those keywords into a structured content map before you write a single post, which is the step that separates random publishing from a compounding SEO strategy.

Can I do keyword research using only Google?

Yes, completely and reliably. Google Autocomplete, People Also Ask, Related Searches, Google Search Console, and Google Keyword Planner are all free tools owned by Google that provide real, current keyword data sufficient for building a complete beginner blog content strategy.

This is the question I needed answered when I started.

The answer is yes. And I mean that without caveats. For the first twelve months of a new blog, Google’s own free tools give you everything you need to make confident keyword decisions.

Google Search Console is the best free keyword research tool for sites that are already live. Google Autocomplete and Related Searches require zero tools and give you real keyword data straight from Google’s search index. Combined with manual SERP analysis, this is enough to find rankable keywords for a new blog without spending anything.

Here is what “using only Google” looks like in practice:

• Google autocomplete – uncovers what people are actually typing right now
• People also ask – reveals the follow-up questions your reader has after the primary query
• Related searches – surfaces semantic variations and adjacent topics
• Google Search Console – shows which queries your published content already ranks for (free, unlimited)
• Google keyword planner – provides search volume data directly from Google’s own ads database (free with a Google Ads account, no ad spend required)

How to group search intent manually using Google autocomplete goes deeper on the intent-grouping process, specifically how to look at autocomplete results and understand whether the reader behind each query wants to learn, compare, or buy.

Is Google keyword planner good for keyword research?

Yes, with one important caveat beginners rarely hear.

Google Keyword Planner was built for advertisers. Its volume data uses broad ranges (100–1K, 1K–10K) rather than exact numbers. That makes it less precise than paid tools for granular decisions.

But for a beginner deciding which keywords to target among a shortlist of five to ten options, the range data is more than enough. “1K–10K monthly searches” tells you there’s genuine demand. “10–100 monthly searches” tells you to look elsewhere.

If your posts aren’t appearing in Google’s index at all – which would make any keyword research effort irrelevant, Why is my new WordPress site not indexing on Google covering the specific technical settings that silently block Google from crawling your content.

How to use Google autocomplete for keyword research – The Alphabet technique nobody else has named

How to use Google autocomplete for keyword research effectively means opening an incognito browser, typing your seed keyword, and watching the dropdown suggestions. Each suggestion is a real query typed by real users. The Alphabet Technique, adding one letter after your seed keyword and cycling through A to Z – multiplies this into dozens of specific keyword ideas in under ten minutes.

Let me show you the exact technique I use every time I start keyword research for a new post.

I call it the Alphabet Technique and in two years of keyword research, I’ve never found a faster way to generate real, long-tail keyword ideas using zero tools.

Here is the exact process :

• Open a browser in incognito mode (important – prevents personalization from biasing your results)
• Go to Google.com
• Type your seed keyword – for example: “keyword research”
• Before pressing Enter, look at the autocomplete suggestions
• Note every relevant suggestion
• Now type “keyword research a” and note what appears
• Then “keyword research b”, and continue through the alphabet
• In 10 minutes you’ll have 30–60 specific keyword variations

Why incognito mode matters :

Google personalizes autocomplete results based on your search history. In incognito mode, you see what the average person searching this topic sees, which is the data you actually want.

I ran this technique on “how to start a blog” and generated 47 distinct keyword variations in eleven minutes.

Of those 47, nine met my targeting criteria (3+ words, 100–1K searches, difficulty under 30). Of those nine, I’ve published posts targeting seven. Six are currently on page one of Google.

How to use Google autocomplete for keyword research isn’t just about finding keywords, it’s about finding the specific question your reader is typing at the exact moment they need your answer.

The PAA boxes extend this significantly. After you identify your primary keyword through autocomplete, search it in Google and study every People Also Ask question. Those are your H2 and H3 subheadings – written by your readers, not by you.

How to find low competition keywords for a new blog – My 3-filter competition system

How to find low competition keywords for a new blog requires filtering every keyword candidate through three checks: length (three or more words), volume (100–1,000 monthly searches), and difficulty (under 30). Keywords that pass all three filters are your realistic ranking opportunities. Keywords that fail any filter go on a future list for when your domain has more authority.

This is the framework that changed my ranking results more than any other single change.

Before I systematized this, I was picking keywords based on what felt interesting. Some were too competitive. Some had no traffic. Most went nowhere. After I built the 3-Filter Competition System, every keyword I targeted had at least one first-page ranking within six months.

The 3-Filter competition system :

Filter 1 – Length check (Pass: 3+ words)

A three-word keyword like “keyword research blog” is still too competitive for a new site. The sweet spot for new blogs is four to six word phrases that match a specific question or intent.

“How to do keyword research for a blog for free” passes Filter 1. “Keyword research” fails.

Filter 2 – Volume check (Pass: 100-1000 searches/month)

Look for keywords with decent search volume of 100–1,000 monthly searches for new sites. Avoid targeting keywords with difficulty scores above 30 if your site is new.

Use Google Keyword Planner to check volume. The free account shows ranges — “100–1K” is your target range. “10–100” is too thin. “1K–10K” is worth attempting on a stronger domain.

Filter 3 – Difficulty check (Pass: Under 30)

Check difficulty using Ubersuggest’s free Chrome extension (unlimited use, no daily limit) or the first page of Google itself.

If the first page of results is dominated by Wikipedia, Forbes, and established blogs with millions of backlinks — the keyword fails Filter 3 regardless of what difficulty tools say.

My personal threshold: I don’t target anything above 25 on a new domain. The window between “enough search volume to matter” and “low enough competition to win” is where all my early rankings live.

What is good keywords difficulty score for a new blog?

Under 30 using any standard keyword difficulty metric. Under 25 on a domain under twelve months old.

Difficulty scores vary between tools, but the principle stays constant: if the people currently ranking for this keyword have dramatically more backlinks, domain authority, and content depth than you, you need a different keyword.

How do I find what keywords my competitors rank for free?

Go to Google and search your target keyword. Open every page on the first page of results. Look at the keywords they target in their H2 and H3 headings. Check their internal link anchor text. Scan their PAA sections.

This manual SERP analysis reveals what keyword variations your competitors are capturing and more importantly, the gaps they’re missing that you can fill first.

Why your blog is not getting traffic after 6 months addresses what happens when you’ve published keywords that aren’t ranking, including whether keyword selection or something else is the root cause.

How to do keyword research without Ahrefs/ SEM Rush – The free tool stack covers everything a beginner needs

How to do keyword research without Ahrefs uses five genuinely free tools in combination: Google Autocomplete (zero cost), Google Keyword Planner (free with Google Ads account), Google Search Console (free for any live site), AlsoAsked (free for limited searches), and Ubersuggest’s Chrome extension (unlimited free). Together these cover keyword discovery, volume checking, difficulty assessment, and content gap identification.

Let me be completely honest about free tool limitations before listing them.

Some tools marketed as “free” provide barely usable data on their free tier. Others are free but require workarounds to get meaningful results. I’ve tested all of these on my own blog. This is what actually works:

The free tools stack :

1 . Google completely + Related searches

• Cost: Completely free
• What it does: Real-time keyword discovery from Google’s live search index
• How I use it: Alphabet Technique for initial discovery, Related Searches for semantic expansion
• Limitation: No volume data

2 . Google keyword planner

• Cost: Free with a Google Ads account (no spend required)
• What it does: Volume ranges and competition level from Google’s own data
• How I use it: Volume check after initial keyword list is built from Autocomplete
• Limitation: Volume ranges rather than exact numbers

3 . Google search Console

• Cost: Free for any verified site
• How I use it: Monthly audit to find keywords where I’m ranking positions 5–15 that I can push to positions 1–3 with content updates
• Limitation: Only works for content you’ve already published

4 . AlsoAsked.com

• Cost: Free (unlimited use)
• What it does: Shows keyword difficulty and search volume directly in Google search results
• How I use it: Run a search in Google, the extension overlays difficulty data on autocomplete suggestions immediately

How to do keyword research without Ahrefs using these five tools follows a specific sequence, which is the full 5-Step System in the next section.

How to do on-page SEO for blog posts shows what happens after you’ve found your keywords, specifically how to use them inside your content in the places that actually affect rankings.

How to optimize blog posts for SEO beginners is the complete optimization walkthrough that takes your researched keywords from your spreadsheet into your post in a way Google can evaluate and rank.

The 5 step free keyword research system – The complete workflow from zero to publishing list

The complete free keyword research system follows five steps: brainstorm seed keywords, run the Alphabet Technique on each seed, mine PAA questions for your shortlist, filter every candidate through the 3-Filter Competition System, then organize passing keywords into topic clusters in your content planner. The full workflow takes two to three hours for a complete month’s content calendar.

I run through this system once per month. It takes me between two and three hours for a complete content calendar of twelve to fifteen posts.

Step 1 – Seed keyword brainstorming

Write down five to ten broad topics your blog covers. Don’t research yet. Just think about what your reader is struggling with, what problems they’re trying to solve, and what questions they ask before they reach you.

These become your seed keywords, the starting points for everything else.

Step 2 – Alphabet technique expansion

Take each seed keyword and run it through the Alphabet Technique in incognito mode. You should generate thirty to sixty keyword variations per seed.

Add every relevant result to a working document without filtering yet. The filtering happens in Step 4, not here.

Step 3 – PAA mining

Search each of your best keyword candidates in Google. Screenshot or copy every People Also Ask question that appears.

These questions are your future H2 and H3 subheadings. They’re also potential cluster post topics in their own right.

A keyword that generates fifteen PAA questions has enough content depth for a full topic cluster, not just a single post.

Step 4 – 3 Filter competition check

Run every keyword through the 3-Filter Competition System:

• Length : Three or more words? Pass
• Volume : 100-1000 monthly searches (check in Keyword Planner)? Pass
• Difficulty : Under 30 (check with Ubersuggest Chrome extension)? Pass

Any keyword that passes all three goes on your publishing list.

Step 5 – Topical cluster organization

Don’t publish keywords randomly. Group every keyword that passed filtering into clusters of related topics. One cluster = one pillar post + eight to fifteen cluster posts organized around that pillar.

This is the step that turns keyword research from a publishing list into a topical authority strategy.

How to rank blog posts faster using internal links is what makes the cluster structure work, the specific linking pattern between pillar and cluster posts that signals topical authority to Google faster than any other on-page technique.

For updating old posts with new keyword data, which becomes a monthly priority once you’ve been publishing for a few months, no traffic? how to update old blog posts to get more clicks shows the exact keyword-refresh process that recovers declining post rankings.

And once your full keyword system is in place, how to use keywords the right way covers the in-content placement rules, which positions matter most, what keyword density means in 2026, and which “optimization tricks” from 2020 actively hurt rankings today.

My predictions – What free keyword research looks like in 2027

I’m adding this section because I think the keyword research conversation is about to shift in a way most beginner bloggers haven’t seen coming yet.

Prediction 1 : Conversational keyword queries will overtake traditional head terms as the primary targeting unit.

As voice search and AI chat interfaces handle more queries, the keywords that get answered are not “keyword research” — they’re “how do I find keywords for my blog without paying for tools.”

The free tools that extract these conversational queries (Autocomplete, PAA) become more valuable, not less.

Prediction 2 : Google Search Console will add AI Overview query filtering within 12-18 months.

When this happens, every blogger will be able to see exactly which queries their content is being cited for in AI Overviews — not just traditional organic clicks. The keyword researchers who have been building AEO-structured content from the beginning will have a significant first-mover advantage in that data.

Prediction 3: The “semantic cluster” will replace the “single keyword” as the fundamental targeting unit.

Right now, most bloggers optimize posts for one primary keyword. By 2027, the bloggers winning in AI search will be optimizing for clusters of semantically related queries simultaneously, which is exactly what the 5-Step System is already built to do.

The good news: free tools support this direction better than paid tools right now. Autocomplete, PAA, and Related Searches map semantic clusters naturally. Paid tools still primarily show single-keyword data.
