Keyword Research Tool

The Keyword Research Tool finds keyword ideas based on any seed keyword or URL you enter, and returns data on search volume, keyword difficulty, competition level, and cost-per-click for each suggestion. These metrics help you understand how much demand a keyword has, how difficult it is to rank for, and how much commercial value it carries.

Keyword research is the foundation of SEO and content strategy. Without knowing what your audience is actively searching for, it is impossible to create content that earns organic traffic consistently. This tool translates a single starting idea into a structured list of keyword opportunities — complete with the data you need to decide which terms are worth targeting, in what order, and with what type of content.

How to use the Keyword Research Tool

1. Enter a seed keyword in the search field — this is the core term or topic you want to research. For example: "PDF compressor", "keyword density", or "image converter online". Alternatively, enter a URL to research keywords around the content of a specific page.
2. Click Research Keyword. The tool returns a list of related keyword ideas along with search volume, difficulty, competition, and CPC data for each suggestion.
3. Review the results and identify keywords that match your content goals, your site's authority level, and the search intent you want to target.
4. Build your keyword list — select the most relevant terms and use them to plan content structure, headings, FAQ sections, and internal linking across your site.

Starting with a specific, focused seed keyword typically returns more targeted and actionable suggestions than a very broad term. If your initial results feel too general, narrow your seed keyword and run a second search to drill into a particular subtopic or user need.

Understanding keyword research metrics

Each keyword suggestion comes with four data points. Understanding what each one means — and how to use it — is the difference between picking keywords that drive results and chasing terms that look good on paper but never convert.

Practical rule of thumb: the best keywords for most pages sit at the intersection of meaningful search volume, manageable difficulty, and clear search intent alignment. No single metric tells the full story — use all four together when evaluating a keyword.

Keyword research and search intent

Search intent describes the underlying purpose behind a user's query — what they are actually trying to accomplish when they type something into Google. Matching your content type to search intent is one of the most important factors in keyword selection, because Google evaluates whether a page satisfies the intent behind a query, not just whether it contains the keyword.

There are four main intent categories. Understanding which category a keyword falls into tells you what type of page to create for it:

Mismatching content type to intent is one of the most common reasons pages fail to rank despite targeting the right keyword. A keyword with informational intent needs a comprehensive guide, not a product page. A transactional keyword needs a tool or purchase page, not a blog post. Before finalizing a keyword target, check the current first-page results to confirm what content type Google is already rewarding for that query.

How to select the right keywords

Keyword research generates possibilities. Selection is where strategy happens. Use the following framework to move from a raw list of suggestions to a focused, prioritized set of keyword targets:

• Filter by relevance first — remove any keyword that does not genuinely match your content or audience, regardless of its volume or difficulty score. Irrelevant traffic does not convert.
• Match difficulty to your authority — sites with strong domain authority can target competitive terms. Newer or lower-authority sites should focus on lower-difficulty keywords where they can realistically rank. A DR 70 site has room to pursue moderate and high-difficulty terms; a DR 20 site should prioritize terms with difficulty scores under 30.
• Prioritize long-tail keywords early — long-tail keywords are longer, more specific phrases with lower search volume but also lower competition and higher conversion potential. They are the fastest path to ranking for sites that are still building authority.
• Group related terms by page — keywords that share the same search intent and topic can often be targeted within a single page rather than separate pages. Grouping reduces content duplication and concentrates ranking signals on one URL.
• Use CPC as a commercial signal — keywords with high CPC values are worth targeting with commercial or transactional pages even if their search volume is moderate, because the traffic they attract is more likely to convert.
• Verify in the SERP before committing — run a search for your shortlisted keywords and review what currently ranks. Confirm the content type, depth, and quality of the top results. If all top results are from major authoritative domains with extensive content, that keyword may require significant effort to compete for.

The role of long-tail keywords

Long-tail keywords are search phrases that are typically three or more words long and address a specific, defined user need. They have lower search volume than broad head terms, but they compensate for this with lower competition and higher conversion rates.

For example, "keyword research" is a head term with high volume and high competition. "Free keyword research tool for small business" is a long-tail keyword with lower volume, far less competition, and a much clearer indication of what the user needs. A page targeting the long-tail term is more likely to rank and more likely to attract a user who is ready to act on what they find.

For most content strategies — particularly for sites that are not yet established in a competitive niche — a keyword portfolio weighted toward long-tail terms produces faster, more consistent results than competing exclusively for high-volume head terms. The Keyword Research Tool returns both types; using the difficulty and volume metrics together helps you build a balanced mix.

Keyword research applications by use case

• Blog and editorial content — use keyword research to plan article topics around questions your audience is actively asking. Cluster related keywords into pillar articles and supporting posts to build topical authority across a subject area.
• Landing page optimization — identify the specific transactional and commercial keywords your target users search when they are ready to act. These terms belong in page titles, H1s, and the opening paragraphs of conversion-focused pages.
• Tool and product page SEO — research the exact terms users type when looking for a tool or product like yours, including comparison phrases ("X vs Y"), "best" queries, and "free" variants, then ensure your page addresses each of these angles.
• PPC and paid search planning — keyword difficulty and CPC data together identify which terms are worth bidding on. High CPC with moderate difficulty often signals an opportunity where organic ranking reduces dependence on paid spend.
• Competitor keyword gap analysis — enter a competitor's URL to see which keywords they are targeting and use the results to identify gaps in your own content coverage.

Frequently asked questions

What is keyword research?

Keyword research is the process of identifying the words and phrases people type into search engines when looking for information, products, or services related to your topic. It involves evaluating those terms for search volume, competition, difficulty, and intent — then selecting the ones most likely to drive relevant traffic to your content. Effective keyword research is the foundation of both SEO strategy and paid search campaign planning.

What is search volume and how should I use it?

Search volume is the average number of times a keyword is searched per month. It indicates demand, but it does not guarantee traffic — your actual traffic depends on your ranking position, click-through rate, and competition from other results. High-volume keywords attract more competition and are harder to rank for. A balanced keyword strategy includes a mix of moderate-volume terms and long-tail keywords with lower volume but easier ranking potential.

What is keyword difficulty?

Keyword difficulty is a metric that estimates how hard it will be to rank on the first page of Google for a given keyword, typically expressed as a score from 0 to 100. It is calculated by analyzing the authority, backlink profiles, and content quality of the pages currently ranking in the top positions. A score of 0 to 30 is generally considered low difficulty, 30 to 60 moderate, and above 60 high. The appropriate difficulty level to target depends on your site's current domain authority and backlink strength.

What is the difference between competition and keyword difficulty?

Keyword difficulty is an SEO metric reflecting how hard it is to rank organically for a keyword. Competition refers to the level of competition among paid advertisers (PPC) in Google Ads for the same term. A keyword can have high advertiser competition but relatively low SEO difficulty — or vice versa. Use difficulty for organic ranking decisions and competition alongside CPC for paid search planning.

What are long-tail keywords and why do they matter?

Long-tail keywords are longer, more specific search phrases — typically three or more words — that reflect a defined user need. They have lower search volume than broad head terms but also lower competition, making them easier to rank for. They also tend to convert better because they attract users with a clearer, more specific intent. A content strategy that includes a strong foundation of long-tail keywords typically produces faster ranking results and more consistent traffic growth than one focused exclusively on high-volume terms.

How do I choose keywords for a new website or page?

For a new website or a page on a site with limited authority, prioritize keywords with low-to-moderate difficulty scores (typically under 30 to 40) and clear search intent alignment. Look for terms where the current top-ranking pages are not highly authoritative or where the existing content is thin or outdated. Long-tail keywords are the most practical starting point — they offer a realistic path to ranking while you build the authority needed to compete for more competitive terms over time.

Should I research keywords by entering a URL instead of a keyword?

Both approaches are useful. Entering a seed keyword is better for exploring a new topic area or building a keyword list from scratch. Entering a URL is useful for understanding which keywords are associated with an existing page's content — helpful for auditing existing pages, identifying what a competitor is targeting, or finding gaps in your current content coverage.

Is the Keyword Research Tool free to use?

Yes. The tool is free within the daily usage limits shown above. No payment is required. Registering a free account increases your daily limit from 25 to 100 searches and gives access to your usage history.
