What Is Keyword Research? Definition & Guide

Keyword research is the process of discovering and analyzing the search terms that people type into search engines when looking for information, products, or solutions. It is the foundation of SEO content strategy -- helping you understand what your audience is searching for, how often they search for it, how competitive each term is, and which terms are most likely to drive valuable traffic to your site.

Why Keyword Research Matters

Without keyword research, content strategy is guesswork. You might write about topics that nobody searches for, or target phrases so competitive that you cannot realistically rank for them. Keyword research grounds your strategy in actual audience demand -- real data about what real people are looking for right now.

Good keyword research also reveals opportunities your competitors may have missed. Long-tail keywords -- specific, lower-volume phrases with clear intent -- are often less competitive and more likely to convert. A site that builds authority by targeting hundreds of long-tail keywords will often outperform a site chasing only high-volume head terms.

Beyond search volume, keyword research reveals intent -- the why behind the query. Knowing whether someone is looking to learn, compare options, or make a purchase helps you create the right type of content for each query. Mismatching content type to intent is one of the most common reasons pages fail to rank even when they are well-written.

How It Works

Keyword research typically starts with seed keywords -- broad terms related to your product, service, or industry. From those seeds, you use tools like Google Keyword Planner, Semrush, Ahrefs, or Moz to discover related keywords, see search volumes, and assess keyword difficulty. You also look at what terms competitors rank for to find gaps and opportunities.

From the full list, you prioritize. Strong candidates balance decent search volume with manageable competition and clear alignment to your audience's needs. Each priority keyword gets assigned to a content piece -- either an existing page that could be optimized for it, or a new piece to be created.

Averi integrates keyword research into the content planning workflow, so when you are building a brief, keyword data is already surfaced -- including difficulty, volume, and competitor content -- without needing to toggle between multiple tools.

Keyword Research Best Practices

• Start broad with seed keywords, then drill into long-tail variations where competition is lower
• Prioritize search intent -- a keyword with 200 searches and clear buying intent can be worth more than one with 2,000 searches and no clear purpose
• Group related keywords together rather than targeting each with a separate page
• Check competitor rankings to identify the gaps they have left open
• Revisit your keyword list quarterly as search trends shift
• Track keyword rankings for every page you publish to measure SEO progress over time

Frequently Asked Questions

What is the most important factor in choosing which keywords to target? Search intent — does the keyword represent a query where your content can genuinely be the best answer, and does the searcher's intent align with your business goals? A keyword with 10,000 monthly searches but purely informational intent (no commercial value) may be less valuable than a keyword with 500 searches and clear buying intent from your target customer.

How do you find keywords to target? Start with seed keywords from your product and industry, then expand using: Google's autocomplete and "People Also Ask," tools like Ahrefs Keyword Explorer, Semrush Keyword Magic, or Google Keyword Planner, customer interviews (what do they search when looking for solutions like yours?), and competitor keyword gaps. The best keyword lists combine data tools with human customer insight.

What is keyword difficulty and how much does it matter? Keyword difficulty (KD) estimates how hard it is to rank for a keyword based on the strength of pages currently ranking. Higher KD = stronger competition. New sites should target low-difficulty keywords (under 30) where quality content can compete; established sites can attack higher-difficulty terms. KD is a guide, not a rule — content quality and intent match can overcome a difficulty gap.

How often should you revisit your keyword research? At minimum, quarterly. Search volumes shift, new keywords emerge (particularly in fast-moving categories like AI), and your competitive position changes. Also revisit after major product changes, when you enter a new market, or when traffic to key pages drops unexpectedly.

What is long-tail keyword strategy? Long-tail keywords are more specific, lower-volume queries (e.g., "content marketing strategy for early-stage SaaS" vs "content marketing"). They are easier to rank for, often indicate stronger buyer intent, and in aggregate can drive substantial traffic. A long-tail strategy prioritizes dozens or hundreds of specific queries rather than chasing a handful of high-volume terms — it is more achievable for most companies and often converts better.
