The Problem With Most Keyword Research Advice

If you search for keyword research tools online, you will find article after article recommending Ahrefs, Semrush, or Moz as if every beginner has $100–$140 a month sitting spare before they have earned a single commission.

That advice is not wrong exactly. Those tools are powerful. But it is completely backwards for someone just starting out.

Here is the honest truth: you do not need an expensive keyword research tool to begin finding keywords that rank. I know this because ClickRoamer is built almost entirely on free and low-cost tools, and this site is growing steadily in Google Search Console month on month.

n this post I am going to walk you through exactly what free tools exist, what affordable paid alternatives cost, and — most importantly — when it actually makes sense to upgrade from free to paid. This is the guide I wish someone had handed me when I was starting out.

First, What Is Keyword Research and Why Does It Matter?

Keyword research simply means finding the words and phrases people type into Google when they are searching for something. For affiliate marketers, the goal is to find keywords that:

• Have enough people searching for them each month to be worth writing about
• Are not so competitive that established sites dominate every result
• Match the buying intent of someone likely to click your affiliate links

Get this right and your content works for you around the clock. Get it wrong and you spend weeks writing articles nobody finds.

The good news for beginners is that the most powerful signals are available completely free if you know where to look.

The Free Keyword Research Tools Worth Using

1. Google Search Itself (Seriously Underrated)

Before you open any tool, open Google. Type your topic idea and pay close attention to:

Google Autocomplete — the dropdown suggestions that appear as you type are real searches that real people are making right now. These are goldmine long-tail keyword ideas that most beginners walk straight past.

People Also Ask boxes — these question-based results show you exactly what else your audience wants to know around a topic. Each one is a potential article idea or a section within a longer post.

Related Searches at the bottom of the page — scroll to the foot of any search results page and Google hands you eight more related keyword ideas for free.

This is not a workaround. This is live data from the world’s biggest search engine telling you what people are actually searching for. Use it every time.

2. Google Search Console (Only Works Once Your Site Is Live)

If your WordPress site is set up and connected to Google Search Console, this is the single most valuable free tool available to you at the beginner stage.

Search Console shows you:

• Which keywords your pages are already appearing for in Google
• How many impressions and clicks each keyword is getting
• Your average position for each keyword
• Which pages are close to the top 10 but not quite there yet

Those “almost there” keywords sitting in positions 8–20 are your fastest wins. A small content improvement or some internal links can push them into the top 5 where clicks actually happen. No paid tool gives you data this specific to your own site.

3. Ahrefs Free Keyword Generator

Ahrefs offers a free version of its keyword tool at ahrefs.com/keyword-generator. You enter a seed keyword and get back keyword ideas along with basic search volume data and a keyword difficulty score.

The limitations are real — you only see the top 10 results per search and cannot export — but for a beginner checking one keyword at a time before writing a post, it does the job. Use it to quickly sense-check whether a topic has any search demand before investing time in an article.

4. Google Keyword Planner

This is Google’s own keyword research tool, originally built for advertisers running Google Ads. You need a free Google Ads account to access it, but you do not need to spend any money on ads.

Keyword Planner shows you search volume ranges, related keyword ideas, and competition levels. The volume data shows ranges rather than exact numbers on the free tier, which is a bit frustrating, but it is reliable data straight from Google. Great for validating whether a keyword niche has genuine search demand before you commit to writing in that space.

5. AnswerThePublic (Limited Free Searches)

AnswerThePublic takes a seed keyword and generates a visual map of questions, comparisons, and related terms that people search for around that topic. It is particularly useful for finding “how to”, “what is”, and “best way to” style keywords that are perfect for beginner-friendly blog content.

The free version now limits you to a small number of searches per day, so use it strategically rather than burning through your allowance on broad terms.

6. VidIQ (For YouTube Keyword Research)

If you are building a YouTube channel alongside your blog — which I strongly recommend for free traffic — VidIQ’s free tier gives you keyword search volume and competition scores specifically for YouTube searches. I use the paid version which gives many more results.

YouTube and Google are different search engines with different results, so it is worth researching keywords for each platform separately. VidIQ makes YouTube keyword research accessible for free and is a tool I use regularly for planning ClickRoamer video content.

7. Google Trends

Google Trends shows you whether interest in a keyword is rising or falling over time, and lets you compare multiple terms against each other. It is not a keyword volume tool but it is excellent for avoiding keywords that are quietly dying as a topic, and for spotting seasonal patterns in your niche.

Before writing about a topic, a quick Google Trends check tells you whether you are paddling with the current or against it.

The Honest Limitation of Free Tools

Free tools are genuinely enough to get started. I want to be clear about that. However, they have real gaps that become increasingly noticeable as your site grows:

• You can only check one keyword at a time — no bulk analysis or competitor gap research
• Data depth is limited — you do not get backlink data, domain authority checks, or content gap analysis
• No proper competitor research — you cannot see what keywords competing sites are ranking for and identify opportunities they have missed

These limitations matter more once you have 20–30 posts published and are looking to scale your content strategy. At that point, a low-cost paid tool starts to pay for itself. Chat GPT, Claude, Gemini or other Ai tools can give you buyer intent keywords you can outrank what’s already on page one when you use a detailed prompt.

Affordable Paid Tools Worth Considering (When the Time Is Right)

Mangools — Around $29/Month

Mangools is a suite of five tools including KWFinder for keyword research, SERPChecker for analysing competition, and SERPWatcher for rank tracking. The interface is beginner-friendly and the keyword difficulty scores are genuinely reliable for gauging whether a small site can compete.

At around $29 per month on annual billing, it is one of the most affordable proper keyword research tools available. If your site starts generating any income at all, this is a strong first paid upgrade.

KeySearch — Around $17/Month

KeySearch is a budget-focused all-rounder that includes keyword research, competitor analysis, backlink checking, rank tracking, and a YouTube research feature. It is less polished than Mangools but covers more ground at a lower price point, making it a popular choice among affiliate marketers who need more functionality without the Semrush price tag.

Ubersuggest — Around $12/Month

Neil Patel’s Ubersuggest is one of the most affordable entry points into paid SEO tools. It offers keyword ideas, search volume, competition data, and basic site audit features. The data is less comprehensive than Ahrefs or Semrush, but for a beginner building their first affiliate site, it covers the essentials at a price that is hard to argue with.

SE Ranking — Around $65/Month (Essential Plan)

SE Ranking sits in the middle ground between budget tools and enterprise platforms. It includes rank tracking, a site audit tool, keyword research, and competitor analysis. If you are managing multiple websites or want agency-level reporting features without the Semrush price, SE Ranking becomes worth considering once your affiliate income justifies the investment.

The Tools to Avoid Until You Are Earning

Ahrefs ($29–$449/month) and Semrush ($139+/month) are industry-standard tools used by professional SEO agencies. They are excellent. They are also completely unnecessary — and a significant financial burden — for a beginner affiliate marketer who has not yet earned their first commission.

The rule I follow at ClickRoamer is simple: paid SEO tools are for when your site is already generating consistent monthly income. Until then, the free tools listed above are not a compromise — they are exactly what the job requires at this stage.

My Recommended Beginner Keyword Research Workflow (Zero Cost)

Here is the exact process I recommend for finding keywords to write about when you are starting out:

Step 1 — Start with Google Autocomplete. Type your topic into Google and note every suggestion in the dropdown. Write them all down.

Step 2 — Check People Also Ask. Click on a search result, come back to Google, and read through the People Also Ask questions that appear. These are real questions from real people in your niche.

Step 3 — Check competition manually. Search your chosen keyword and look at the first page. Are the results from huge authority sites (Forbes, HubSpot, major brands)? If so, move on. Are some results from smaller blogs or forum threads? That is a signal that a beginner site can compete.

Step 4 — Validate with Ahrefs Free Keyword Generator. Check that the keyword actually has some monthly search volume and a manageable keyword difficulty score. Aim for difficulty scores under 20 to start.

Step 5 — Check Google Trends. Make sure interest in the topic is stable or growing, not declining.

Step 6 — Write your content and track in Google Search Console. Once published, monitor the keyword’s impressions in Search Console over the following weeks. This tells you whether Google is even picking up on the page.

This full workflow costs nothing. It is how ClickRoamer articles are planned, and it works.

Quick Comparison Table

The Bottom Line

Beginners do not need expensive keyword research tools. What they need is to understand how to use the free tools available — and the most powerful one of all is the search engine they are trying to rank on.

Start with Google itself. Add Google Search Console as soon as your site is live. Use the Ahrefs free tool to sense-check your ideas. When your site starts generating regular income — and it will if you are consistent — then consider upgrading to a paid tool that saves you time.

The goal right now is not to have the best tools. The goal is to publish useful, well-targeted content consistently. The tools just help you aim.
