What it does
SEO Content Gap is an agent skill from zubair-trabzada/dataforseo-claude. Find keywords competitors rank for that you don't, via the DataForSEO Labs domainintersection endpoint. Surfaces the highest-leverage content opportunities sorted by search volume and the competitor's ranking position, with cross-competitor consensus signals.

What it can do on your machine
Read from SKILL.md and the folder at commit 67ac4f0. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
BashWrite
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are bash).
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
dataforseo.com
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names these keys or tokens, usually read from environment variables:
DATAFORSEO_PASSWORD
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
SEO Content Gap loads about 823 tokens when it runs. Until then it costs about 69 tokens; SKILL.md has 309 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check: notes
The automated check noted patterns worth knowing about, such as sudo or a known installer.

2. Write them to `~/.claude/skills/seo/.env`: - NoteMentions a .env fileSKILL.md:34

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Phase 0: Credential Preflight (REQUIRED — run BEFORE anything else)
Before running any of the steps below, always invoke the shared preflight check:
~/.claude/skills/seo/scripts/preflight.shIf exit code is 0: credentials are configured — proceed with the rest of this skill silently.
If exit code is 2: the script prints the DataForSEO setup wizard to stdout. STOP, display that wizard to the user verbatim, and wait for them to paste credentials in this format:
login: their_email@example.com
password: their_api_password_hereWhen they reply:
- Parse
login:andpassword:from their message. - Write them to
~/.claude/skills/seo/.env:DATAFORSEO_LOGIN=<login> DATAFORSEO_PASSWORD=<password> chmod 600 ~/.claude/skills/seo/.env- Run a verification call:
~/.claude/skills/seo/scripts/keyword_research.py volume "test" - If verification succeeds (real JSON returned): tell the user "✅ Credentials verified. Running your command now..." and proceed with the original request.
- If status
40104 — Please verify your account: tell the user to verify their account at https://app.dataforseo.com/, then say "continue" to retry. - If any other auth error: ask them to double-check the API password (the long alphanumeric string from https://app.dataforseo.com/api-access — not their account login password).
Never echo credentials back to the user, never include them in tool output, and never commit them.
Content Gap Skill
Powered by: DataForSEO API — Labs
domain_intersection(target1=competitor, target2=you, intersections=false). Cost: ~$0.02 per competitor compared.
Run
~/.claude/skills/seo/scripts/domain_overview.py content_gap --you <you> --competitors <c1> <c2> <c3>You can pass 1–5 competitors. The script returns, per competitor, the keywords where they rank in the top 100 and you don't.
Sort and surface
For each competitor's gap list, sort by:
priority = search_volume * (101 - competitor_position)Higher = the competitor is ranking high for a high-volume keyword you have nothing for — hot opportunity.
Output structure
For each competitor:
Gap vs <competitor>: <N> keywords where they rank, you don't
Top 10 to pursue:
1. "<keyword>" — they're #<pos>, vol <V>, KD <D>, $<CPC>
→ They rank a <page_type> at <url>
2. ...Cross-competitor consensus
After processing all competitors, find keywords that multiple competitors rank for. These are the strongest signals — if every competitor has content on a topic and you don't, that's a clear hole in your strategy.
Consensus gaps (3+ competitors rank, you don't):
- "<keyword>" ← 4 competitors rank top 20
- "<keyword>" ← 3 competitors rank top 10End with a 5-article content roadmap with target keyword, working title, priority score, and which competitor's article to study.
