Semrush Tool

Note: LocalSEOData (localseodata-tool) now covers keyword suggestions, search volume, keyword trends, and keyword opportunities. Use LocalSEOData as default. Semrush remains the stronger choice for advanced keyword gap analysis, Keyword Magic Tool, and combined keyword + site audit workflows.

Semrush has an official MCP server. When connected, use it for keyword research, competitive organic analysis, and technical site audits. This is your primary keyword intelligence tool.

Core Workflows

Local Keyword Research

When: User needs to find keywords to target with volume and difficulty data.

What to pull:

  1. Keyword Overview: Volume, KD, CPC, SERP features for target keywords
  2. Keyword Magic Tool: Related keywords from a seed term (e.g., "plumber buffalo" → generates hundreds of variations)
  3. Keyword Gap: Compare user's domain vs 2-3 competitors to find keywords competitors rank for that user doesn't

How to interpret for local:

  • Volume under 100/mo is common for local keywords — that's normal and still valuable
  • KD under 40 for local service keywords is achievable
  • CPC above $5 means high commercial intent — prioritize these
  • Look for keyword clusters: same service, different locations (e.g., "dentist Orchard Park," "dentist Hamburg," "dentist West Seneca")

What to do with the data:

  • Group keywords by service category
  • Map keywords to existing or needed pages
  • Identify gaps where competitors rank but you don't
  • Feed into local-keyword-research skill for full keyword strategy
  • Feed into local-landing-pages skill for page creation

Competitor Organic Analysis

When: User wants to know what keywords competitors rank for or how they compare.

What to pull:

  1. Domain Overview: Total organic keywords, traffic estimate, top keywords
  2. Organic Research: All keywords a competitor ranks for with positions
  3. Keyword Gap: Side-by-side comparison showing where competitor ranks and you don't

What to look for:

  • Keywords where competitor ranks top 10 and you rank 11-20 (quick wins — you're close)
  • Keywords where competitor ranks and you don't rank at all (content gaps)
  • Keywords where you rank higher than competitor (protect these)
  • Competitor's top traffic-driving keywords (understand their strategy)

Technical Site Audit

When: User needs a crawl of their website for technical issues.

What Semrush's audit catches:

  • Broken links (internal and external)
  • Missing/duplicate title tags and meta descriptions
  • Slow pages
  • Redirect chains
  • Missing schema markup
  • Crawlability issues
  • HTTPS issues

For local specifically, check:

  • Location page titles: unique per location?
  • Location page meta descriptions: unique per location?
  • Internal linking to location pages
  • Schema presence on location pages
  • Canonical tags on similar location pages

When to use Screaming Frog instead: If you need custom extraction (NAP data, specific schema fields) or the site has 1000+ location pages, Screaming Frog gives more control.

Position Tracking

When: User wants to track keyword rankings over time at a specific location.

  • Set location to city/ZIP level
  • Track target keywords weekly
  • Compare against competitors in the same tracker

When to use Local Falcon instead: For local businesses, geogrid ranking (Local Falcon) is more meaningful than point-based position tracking (Semrush) because rankings vary by searcher location. Use Semrush position tracking for organic rankings, Local Falcon for map pack rankings.

Key Data Points and What They Mean

MetricWhat It IsWhat It Means for Local SEO
Search VolumeMonthly searchesUnder 100 is normal for local — still valuable if intent is high
Keyword Difficulty (KD)How hard to rank organicallyUnder 40 = achievable for local businesses with good content
CPCCost per click in Google AdsHigh CPC = high commercial intent = priority keyword
Competitive DensityHow many advertisers bid on this keywordHigh density = proven money keyword
SERP FeaturesWhat appears in results (local pack, ads, PAA, etc.)Local pack present = GBP optimization matters for this keyword
TrafficEstimated monthly organic visitsRelative metric — compare competitors to each other

Default next step: Keyword data without a page plan is just a spreadsheet. Always map keywords → pages → publish → measure.
