Keyword research is not about collecting the largest possible spreadsheet. It is about learning what your audience wants, how they describe the problem, and what kind of page would genuinely help them.

Free tools can provide enough evidence to plan a focused new site, but none of them can guarantee search traffic or rankings. Each tool answers a different question, and its limitations matter.

Quick Takeaways: Use several sources rather than trusting one number, treat Keyword Planner as an advertising tool, check current search results for intent and competition, group related queries into useful pages, and use Search Console data after publication to improve the plan.

Start with the audience, not the tool

Write down the audience, its main problem, and the words people might use when asking for help. These starting phrases are often called seed topics.

For a site helping apartment renters grow herbs in low-light rooms, seed topics might include “low-light herbs,” “indoor herb garden,” “small grow light,” and “herbs safe for cats.” The phrases are not yet a content plan. They are starting points for research.

1. Use Google autocomplete for ideas

Type a seed phrase slowly and record useful predictions. Try natural variations such as:

Autocomplete predictions reflect real search activity, but they also vary by language, location, trends, and previous activity. A prediction is evidence that a phrase is relevant enough to appear, not proof of high monthly volume.

2. Check Google Trends for timing and direction

Google Trends shows relative interest over time. It can help you spot seasonal topics, compare terminology, and notice whether interest is rising or declining.

A Trends score is not a search count. Compare related terms over the same location and period, and remember that very small topics may not return enough data.

3. Use Keyword Planner for advertising estimates

Google Keyword Planner can suggest related phrases and provide historical search ranges and advertising forecasts. Google currently requires users to complete Google Ads account setup and enter billing information to access basic Keyword Planner features.

The competition and bid columns describe the paid advertising market. They do not measure how difficult it will be to rank organically, and they do not predict your AdSense RPM or income.

4. Learn the audience’s language from communities

Forums, Reddit discussions, reviews, support groups, and question sites can reveal how people describe a problem when they are not trying to write a search-friendly phrase.

Use these sources to identify confusion, missing explanations, and vocabulary. Do not assume that every popular discussion has meaningful Google search demand. Respect community rules, avoid copying personal stories, and verify factual advice before repeating it.

5. Review People Also Ask and related searches

When Google displays People Also Ask or related-search features, use them to discover nearby questions and different interpretations of the topic. These features do not appear for every search and can change over time.

Do not create a separate article for every wording variation. Several closely related questions may belong on one complete page.

6. Inspect the live search results

Search a representative query and identify the dominant page types. A results page may contain guides, product pages, videos, forums, local listings, tools, or a mixture.

Ask whether your planned page matches the likely need. Also consider:

Forums or small sites in the results do not automatically mean a query is easy. Major brands do not automatically make it impossible. This is a judgment based on relevance, quality, credibility, and what you can contribute.

A worked keyword example

Suppose the seed topic is “low-light indoor herbs.” Research may reveal questions about which herbs tolerate low light, how many hours a grow light needs, watering in small containers, pet safety, and signs of weak growth.

Those ideas could become a small content group:

Several wording variations about the “best low-light herb” would probably belong in the central guide rather than becoming separate, repetitive articles.

Build a useful content map

Sort your findings by the job the reader is trying to complete:

Choose one page for each distinct purpose. Map closely related queries to that page and plan descriptive internal links between related topics.

Pro Tip: Save the search date, location, and main observations with your notes. Search results and tool interfaces change, so this context will help you understand why an earlier content decision was made.

Keyword research checklist

The Bottom Line

Free tools are enough to build a sensible first content plan when you understand what each source can and cannot tell you. Use them to learn the audience’s language, compare interest, review the existing results, and choose pages that solve distinct problems. Then validate the wider business idea with the niche-validation framework.

Frequently Asked Questions

Is Google Keyword Planner free?

There is no separate Keyword Planner subscription, but Google currently requires a completed Google Ads account setup with billing information to access its basic features. Check Google’s current instructions before starting.

Does a high CPC mean a keyword is easy to rank for?

No. CPC concerns paid advertising. Organic ranking depends on relevance, content quality, links, competition, technical access, and many other factors.

How many keywords should I collect?

There is no required total. Collect enough evidence to plan distinct, useful pages without turning minor wording variations into separate articles.

Can I use Search Console for a new site?

Yes, but it becomes more useful after Google begins recording impressions and clicks. See the Search Console setup guide.

Should I choose only low-competition phrases?

No. Choose topics that fit the audience and your ability to provide a useful answer. A mix of focused and broader questions can create a more natural site.
