How to Use Semrush for Keyword Research: A Step-by-Step Workflow

Semrush's Keyword Magic Tool is the part of the platform most people actually use, and also the part most people use badly. The tool works from a database of tens of billions of keywords, but a bigger number doesn't make a research process better on its own - what makes it useful is a workflow that goes from a raw keyword list to a defensible content plan. Here's the version of that workflow that actually holds up, not just the "type in a word, sort by volume" version.

For context on what Semrush is and what it costs before diving into workflow, see our full Semrush profile. If you're deciding between Semrush and Ahrefs for this specific task, our Semrush vs Ahrefs comparison covers where each tool's keyword data actually differs.

Step 1: Start Broad in the Keyword Magic Tool, Then Narrow by Match Type

Enter a single seed word or short phrase - not a long-tail guess, a genuinely broad term for the topic you're targeting. Semrush returns a table of related terms grouped into topic-specific subgroups, which is where most of the actual value is: the subgroups surface angles on a topic you wouldn't have thought to search for directly.

Before doing anything else, check the country flag next to the search bar. Keyword volumes vary significantly by country, and the default isn't always the market you're targeting - this is the single most common setup mistake that quietly skews an entire research session.

From there, use match type to control breadth: Broad Match shows the widest set of related keywords, Phrase Match narrows to terms containing your exact phrase, and Exact Match narrows further to close variants of the term itself. Start in Broad Match to see the shape of the topic, then narrow to Phrase or Exact once you know which specific angle you're building content around.

Step 2: Don't Trust the List Until You've Validated It in Keyword Overview

The Keyword Magic Tool is a discovery tool, not a final source of truth. Every keyword worth acting on should get a pass through Keyword Overview before it goes on a content plan - this is where you confirm search intent (informational, commercial, transactional, navigational), check keyword difficulty against your site's actual current authority, and see which SERP features are already occupying the results page for that term.

This step is the one most commonly skipped, and it's the reason keyword lists produced from Magic Tool alone tend to include terms that look promising on volume and difficulty but are actually informational searches you're targeting with a commercial page, or vice versa. A keyword with strong volume and low difficulty is worthless if the intent doesn't match what the page is trying to do.

Step 3: Find What You're Missing With Competitor Gap Analysis

Once you've validated your own keyword ideas, the next real opportunity is usually sitting in a competitor's ranking profile, not in more brainstorming. Open Organic Research, enter a competitor's domain, and pull their Positions report - this shows every keyword they rank for, along with search volume, difficulty, intent, and estimated traffic per term.

Run this against two or three real competitors, not just the obvious market leader - a mid-sized competitor's ranking list often surfaces more realistically-winnable keywords than a dominant player's. Cross-reference their ranking keywords against your own list from Step 1 and Step 2: the terms they rank for that you don't are your actual content gap, not a generic brainstorm of "topics we should probably cover."

Step 4: Organize by Intent and Funnel Stage, Not Just Volume

A raw list sorted by search volume produces a content plan that's technically ranked by opportunity size and practically useless for sequencing what to write first. Group validated keywords by search intent and funnel stage instead: informational terms map to top-of-funnel content (guides, definitions, explainers), commercial-investigation terms map to comparison and "best of" content, and transactional terms map to service or product pages directly.

This is also where a lot of teams should be honest about capacity: a full research session across a competitive niche can easily surface enough validated keywords for three to six months of publishing. Treating that list as a prioritized backlog - not a task list to clear in the next two weeks - is what keeps the output usable instead of overwhelming.

Step 5: Set Up Position Tracking Before You Publish, Not After

The last step people skip is the one that makes the previous four worth anything: add your target keywords to Position Tracking before content goes live, not weeks later once someone remembers to check rankings. Tracking from day one gives you an actual before/after baseline instead of a vague sense that "rankings improved," and it's the only way to catch a keyword that isn't moving early enough to actually do something about it - a content refresh, an internal linking pass, a technical fix - instead of finding out three months in that a page never ranked at all.

What This Workflow Actually Produces

Done properly, this isn't a keyword list - it's a prioritized content plan with intent-mapped topics, a competitive gap analysis backing up why each topic was chosen, and tracking already in place to measure whether it worked. That's a meaningfully different deliverable than what "type a word into Keyword Magic Tool and sort by volume" produces, and it's the difference between keyword research that informs a content calendar and keyword research that just generates a spreadsheet nobody references again after the first week.
