SemRush Research

Pull live SEO and competitive intelligence data from the SemRush API.

Prerequisites

Requires SEMRUSH_API_KEY set in .env, .env.local, or ~/.claude/.env.global.

bash

# Verify the key is available
echo "SEMRUSH_API_KEY is ${SEMRUSH_API_KEY:+set}"

If the key is not set, instruct the user:

You need a SemRush API key. Get one at https://www.semrush.com/api/ Then add SEMRUSH_API_KEY=your_key to your .env file.

API Base

All requests go to https://api.semrush.com/ with the API key passed as &key={SEMRUSH_API_KEY}.

Responses are semicolon-delimited CSV. The first line is the header row. Parse accordingly.

Workflow: Full Competitive Analysis

When the user asks for a full competitive analysis, run these steps in order:

Domain Overview - Get the target domain's metrics
Competitor Discovery - Find top 5-10 competitors
Domain Overview for each competitor - Compare metrics
Top Keywords for each domain - Find keyword gaps
Backlink Overview for each domain - Compare link profiles

Output Format

Present results as a comparison table:

| Metric              | target.com | competitor1.com | competitor2.com |
|---------------------|-----------|-----------------|-----------------|
| SemRush Rank        | ...       | ...             | ...             |
| Organic Keywords    | ...       | ...             | ...             |
| Organic Traffic     | ...       | ...             | ...             |
| Traffic Cost        | ...       | ...             | ...             |
| Backlinks           | ...       | ...             | ...             |
| Referring Domains   | ...       | ...             | ...             |

Then highlight:

Keyword gaps: Keywords competitors rank for but target does not
Quick wins: Keywords where target ranks positions 5-20 (improvement opportunities)
Content gaps: Topics competitors cover but target does not
Backlink opportunities: Sites linking to competitors but not target

Rate Limits and Costs

Each API call costs API units (check your plan)
Use &display_limit= to control result count (default varies by endpoint)
Cache results locally when doing multi-step analysis to avoid redundant calls
Domain overview calls are cheapest; backlink and traffic analytics cost more

Error Handling

Error	Meaning
`ERROR 50 :: NOTHING FOUND`	No data for this query
`ERROR 120 :: WRONG KEY`	Invalid API key
`ERROR 130 :: LIMIT EXCEEDED`	API unit limit reached
Empty response	Usually means no data available for the query parameters

When you get "NOTHING FOUND", try:

Different database (e.g., uk instead of us)
Root domain instead of subdomain
Broader keyword phrase
