About this tool
Keyword research is the foundation of any SEO strategy, but paid tools like Ahrefs and Semrush cost hundreds of dollars monthly. This tool provides a fast way to expand one seed idea into a handful of related terms for content brainstorming, without a subscription.
It's honest about what it isn't: the Interest score and Opportunity percentage are calculated estimates, not real search volume or competitive difficulty data, so treat this as an ideation starting point and validate anything promising in a dedicated keyword tool like Google Keyword Planner.
This tool expands one seed keyword into a short list of related term suggestions, pulled from Wikipedia's public article-suggestion API, then attaches an "Interest score" and an "Opportunity" percentage to each - both computed estimates based on term length and the Competition Level you enter, not real search volume or ranking-difficulty data. Use it for quick topic brainstorming, then validate anything promising in a real keyword tool.
How to Use Keyword Research Companion
Enter Seed Keyword
Provide your base keyword and optional industry to tune the output.
Estimate Volume
The tool models average searches and competition pressure.
Spot Opportunity
Review opportunity score to identify low-competition ideas.
Capture Variations
Copy the generated list or drop it into your draft keyword plan.
Common Workflows
Enter a Seed Keyword
Type your starting keyword or topic, choose an Industry (used only as a fallback if live suggestions aren't available), and set a Competition Level from 0-100.
Run the Analysis
Click Run Live Analysis to pull up to 6 related term suggestions with an Interest score and Opportunity percentage for each.
Read the Estimates Honestly
Treat the Interest score and Opportunity percentage as directional estimates influenced heavily by the Competition Level you entered - not real search or ranking data.
Export and Validate Elsewhere
Copy or download the results, then check any promising ideas in a free tool like Google Keyword Planner before acting on them.
Best For
- Expands a seed keyword into up to 6 related suggestions pulled from Wikipedia's public opensearch API - if that source is unavailable, it falls back to a short list of industry-specific modifier words.
- Interest score and Opportunity percentage are both formulas based on suggestion length, your seed keyword, and the Competition Level number you enter yourself - not real search volume or live SERP difficulty data.
- Copy or download every result as a plain-text snapshot for your own notes.
Examples
The same suggestion at two different Competition Level inputs
Input
Seed "seo audit", suggested term "SEO tools", Competition Level 20 vs. Competition Level 80Result
Competition 20 → Interest score 2,265, Opportunity 89%. Competition 80 → Interest score 1,905, Opportunity 29%.Both scores are computed directly from the Competition Level you type in, plus the suggested term's own length - the same suggestion produces very different numbers depending only on what you enter for Competition Level, since no real search or ranking data is involved.
Use Cases
Brainstorming blog post topics from one seed idea
Enter a broad topic to get a handful of related term suggestions to spark content ideas.
Quickly sense-checking a topic before deeper research
Use the suggestions as a starting list, then validate the promising ones in a real keyword tool.
Exporting a quick idea list for a content calendar
Copy or download the results as a plain-text snapshot to paste into your own planning docs.
Common Mistakes
Problem
Treating the Interest score as real search volume
Solution
It's a formula based on the suggested term's length and your Competition Level input - not data from any search engine or keyword database.
Problem
Treating the Opportunity percentage as SERP difficulty
Solution
It's calculated as roughly 100 minus your own Competition Level input - it doesn't reflect actual ranking competition for that term.
Problem
Assuming suggestions come from a keyword database
Solution
Suggestions are pulled from Wikipedia's public article-search API - if that's unavailable, the tool falls back to a short list of generic industry modifier words instead.
Problem
Expecting the Industry field to change the live suggestions
Solution
Industry only affects the fallback suggestion list used when Wikipedia's suggestions aren't available - it doesn't filter or influence the live results.
Problem
Making SEO decisions based on these numbers alone
Solution
Use this for quick brainstorming only, then validate anything promising in a dedicated tool like Google Keyword Planner before acting on it.
Tips & Best Practices
Adjust Competition Level to see the range of possible scores
Since Opportunity is derived directly from what you enter here, try a few different Competition Level values to understand how much it's driving the number.
Use broad, simple seed keywords
Since suggestions come from Wikipedia's article-title search, broader topic phrases tend to return more relevant related terms than very specific long-tail phrases.
Always validate before publishing content around a suggestion
Check any promising idea in Google Keyword Planner, Google Search Console, or another dedicated keyword tool before committing real content effort to it.
Export your session before starting a new seed keyword
Copy or download the results first, since running a new search replaces the current result set.
Limitations
No real search volume data
The Interest score is a formula based on term length, your seed keyword, and your Competition Level input - it isn't sourced from any search engine's actual query data.
No real keyword difficulty data
The Opportunity percentage is calculated mostly from the Competition Level you type in yourself - it isn't a live SERP difficulty score.
Suggestions come from Wikipedia, not a keyword database
The live suggestion source is Wikipedia's public opensearch API, not Google, Bing, or any dedicated keyword research database - results reflect Wikipedia article titles, not actual search query patterns.
Fallback suggestions are a short, fixed list
If Wikipedia's API is unavailable, the tool falls back to 1-3 generic modifier words per industry (only 5 industries are covered) rather than a live source.
Up to 6 suggestions per search
Each run returns at most 6 related terms.
No saved history
Each search is a one-time result on the page - previous seed keywords and results aren't saved between visits.
Comparisons
This Tool vs. a Real Keyword Data Platform

Which should you use?
Use this tool for a fast first pass at topic ideas, then validate anything promising with a platform that's actually built on real search data before making content decisions.
FAQs
The most common question is where the numbers come from. The Interest score and Opportunity percentage are both calculated estimates - based on the suggested term's length, your seed keyword, and the Competition Level you enter - not real search volume or live SERP difficulty data. The suggestions themselves come from Wikipedia's public search API, not a dedicated keyword database. The FAQ below covers how to validate ideas for free elsewhere.
Does this tool show exact search volume?
No. It models directional interest levels so you can prioritize ideas quickly before validating them in a dedicated SEO platform.
Is the competition score reliable?
It is a lightweight directional input, not a live SERP difficulty score, so treat it as prioritization help rather than source-of-truth data.
Where does this tool's data come from?
Keyword suggestions are pulled from Wikipedia's public article-search API (or a small fallback list if that's unavailable) - not from a search engine's keyword database. The Interest score and Opportunity percentage are both calculated estimates based on term length and the Competition Level you enter, not real search volume or ranking-difficulty data.
How should I validate these ideas before using them?
Check anything promising in a tool that uses real search data, such as Google Keyword Planner (free) or a paid platform like Ahrefs or Semrush, before committing content effort to it.
