How to Do a SEO How to Do Keyword Research

Keyword research is the process of identifying the search terms your clients' target audience actually uses when looking for their products, services, or information. Rather than guessing which words matter, you're gathering data about search volume, competition, intent, and relevance. This becomes your foundation for on-page optimization, content strategy, and paid search campaigns. You're essentially reverse-engineering what people are typing into Google, then building your client's website and content around those specific queries.

For agencies, keyword research directly impacts your ability to deliver measurable results. When you skip this step or do it poorly, you end up optimizing for terms nobody searches for or targeting keywords so competitive that ranking takes months longer than it should. This frustrates clients, damages your reputation, and wastes billable hours on dead-end strategies. Conversely, solid keyword research lets you identify quick wins—lower-volume terms with less competition that your client can rank for within weeks. You also uncover content gaps where your client can capture traffic their competitors are ignoring. This is how you build trust and demonstrate real SEO value instead of vague promises about "improving visibility."

Practically, start with your client's core business terms and brainstorm related queries their customers would search. If they're a personal injury lawyer in Denver, you're not just looking at "personal injury lawyer"—you're finding "car accident attorney Denver," "slip and fall lawyer," "dog bite lawyer Colorado," and variations that match different stages of the customer journey. Use tools like Google's Keyword Planner (free through Google Ads), SEMrush, Ahrefs, or Moz to pull real search volume data and competition metrics. Check Google's autocomplete suggestions and People Also Ask sections—these reveal actual search patterns. Look at what your client's current competitors rank for by entering their domain into your keyword tool, then identify gaps where they're weak but demand exists.

Filter your list by intent alignment and feasibility. A keyword with 10,000 monthly searches means nothing if it's worth zero business revenue or if the top 10 ranking pages are from Fortune 500 companies. You're looking for terms where search intent matches your client's offering and where they have a realistic chance of ranking within your engagement timeline. For most agencies working with small-to-medium businesses, this means prioritizing long-tail keywords—three to five word phrases that have lower volume but higher conversion intent and lower ranking difficulty. These become your priority list for content creation and optimization. Document everything in a spreadsheet showing keyword, search volume, difficulty score, intent classification, and which pages on the client's site should target each term. This becomes your roadmap for the entire engagement and keeps you accountable to measurable rankings and traffic growth.
