Free Keyword Research Tool

Effective SEO keyword strategy starts with understanding your audience. Enter a seed keyword — a broad term that describes your topic — and our tool expands it into dozens of related keyword ideas with real search volume data, keyword difficulty scores, and trend analysis.

When deciding how to choose keywords for SEO, focus on three factors: search volume (how many people search for it), keyword difficulty (how hard it is to rank), and search intent (what the searcher wants). Our tool surfaces all three so you can make informed decisions.

Start with your primary seed keywords, then identify secondary keywords and long-tail variations. Group related keywords into clusters to build comprehensive content that covers a topic from every angle — this is the foundation of a winning SEO keyword strategy.

Keyword difficulty (KD) estimates how hard it will be to rank in the top 10 organic results for a given search term. Our tool calculates KD based on search popularity, interest stability, and market maturity signals from Google Trends data.

Keywords are scored on a 0–100 scale: Easy (0–29) keywords are ideal for new websites or blogs with low domain authority. Medium (30–59) keywords require quality content and some backlinks. Hard (60+) keywords demand strong domain authority, high-quality backlinks, and comprehensive content. Use the KD filter to quickly find competitive keywords that match your site's current strength.

Understanding the different types of keywords is essential for building a comprehensive SEO strategy:

• Seed keywords — Broad, foundational terms (1–2 words) like "marketing" or "SEO tool" that serve as starting points for research.
• Secondary keywords — Related terms and synonyms that support your primary keyword and help search engines understand your content depth.
• Long-tail keywords — Specific phrases (4+ words) with lower volume but higher conversion, like "best free SEO tool for Mac".
• Local SEO keywords — Location-based terms that help businesses rank in local search results and Google Maps.
• Competitive keywords — High-volume terms your competitors rank for that you want to target as part of your strategy.

Our tool classifies keywords by length (Short, Medium, Long) and by intent (Informational, Commercial, Transactional, Navigational) so you can quickly identify the right types of keywords for each page.

While built primarily for SEO, this keyword research tool is versatile enough for multiple platforms and use cases:

• Amazon keyword research — Find product-related search terms with high commercial intent. Filter by Transactional intent to discover keywords that signal buying readiness, then optimize your Amazon listings and PPC campaigns.
• Shopify keywords — Identify keywords for your product pages, collection descriptions, and blog content. Use the keyword filter to find terms that match your product categories.
• Marketing keywords — Discover trending terms for content marketing, social media campaigns, and paid advertising. The trend score helps you spot rising opportunities.
• Resume keywords — Research industry-specific terms that recruiters search for. Enter job titles or skills as seed keywords to find the most relevant terms for your resume or LinkedIn profile.
• Qualitative research keywords — Academics and researchers can use the tool to discover how people search for topics related to their field, informing literature reviews and research paper keyword selection.

Keywords are the bridge between your content and your audience. They determine where your pages appear in search results, what kind of traffic you attract, and ultimately how many visitors convert into customers.

A well-researched keyword strategy helps you create content that matches user intent at every stage — from informational queries like "what is keyword difficulty" to transactional searches like "best SERP keyword rank tracker". By targeting the right mix of seed keywords, secondary keywords, and long-tail variations, you build topical authority and improve your chances of ranking for competitive keywords over time.

Whether you are optimizing for Google, running an SEO tool on Mac or any platform, or doing Amazon keyword research, the principle is the same: understand what people search for, and create the best content to answer their query.

The meta keywords tag was once a key ranking factor, but Google has officially confirmed it no longer uses it for ranking. However, keyword research itself remains more important than ever.

Instead of stuffing meta keywords for SEO, focus on naturally incorporating your target keywords into titles, headings, meta descriptions, and body content. Use this tool to discover the most relevant terms, then weave them into your content strategy. Your primary keyword should appear in your H1 and title tag, while secondary keywords support the main topic throughout the body.
