SEO Competitor Content Gap (AI)

Drop in your site URL + up to 5 competitor URLs. Get back the exact topical gaps with suggested post titles, target keywords, and word counts. Powered by Claude Sonnet 4.6.

Why this exists

Ahrefs charges $99 to $999 per month to do this. SEMrush charges $129 to $499. You use the feature once a quarter.

This actor charges $0.50 per competitor analysed. No subscription. No annual contract.

What you get back per competitor

Field	Description
competitor_url	URL analysed
your_topic_count	Topic slugs found on your site (from sitemap)
competitor_topic_count	Topic slugs found on competitor (from sitemap)
overlap_count	Slugs you both cover
gaps_count	Slugs only the competitor covers, after AI filtering
top_gap_title	The single highest-priority post title to write
gaps[]	Full ranked list of gaps

Each gap object includes:

• source_slug (the exact competitor URL slug)
• suggested_post_title (sharper than the competitor's, often as a question or contrarian angle)
• target_keyword
• estimated_search_volume_band (low / medium / high)
• recommended_word_count (800 to 3000)
• primary_intent (informational / transactional / navigational / commercial)
• rationale (one sentence on why this gap matters)

Pricing

$0.50 USD per competitor analysed. You only pay for successful analyses. Failed sites (no sitemap, blocked, error) are not charged.

Use case	Competitors	Cost
Single competitor check	1	$0.50
Quarterly competitive review	5	$2.50
Annual industry scan	20	$10.00

Compare to Ahrefs Standard at $179/mo or SEMrush Guru at $229/mo.

How it works

1. Sitemap-first extraction: fetches /sitemap.xml, follows nested sitemap indexes, falls back to homepage link crawl if no sitemap.
2. Slug-based topic comparison: extracts the meaningful slug from each URL (last path segment, cleaned).
3. Set diff: identifies slugs unique to the competitor.
4. AI ranking: Claude Sonnet 4.6 filters out low-value slugs (login, terms, tags), prioritises matches with your target audience, and suggests sharper post titles than the competitor uses.

Inputs

• your_url: your homepage URL
• competitor_urls: array of up to 5 competitor homepage URLs
• your_target_audience: one paragraph describing who you write for. The AI uses this to prioritise gaps that matter for your audience.
• max_pages_per_site: default 60. Higher = more coverage but slower and more compute.
• max_concurrency: default 2. Number of competitors processed in parallel.

Use cases

• Quarterly content strategy: pick your top 5 competitors, get a 50-gap ranked backlog.
• New-site launch: see what the category leader covers that you do not.
• Agency client onboarding: ship the gap report as a $500 deliverable, spend $2.50 to make it.
• Programmatic SEO planning: pull 100s of competitor slugs and prioritise which to write first.

What this actor does NOT do

• It does not check search volume against Google. Use Ahrefs or Keyword Planner for hard volume numbers. The estimated_search_volume_band is an AI estimate, not a measured value.
• It does not write the posts. Pair this with your existing AI writing workflow.
• It does not crawl behind authentication. Public sitemaps only.
• It does not check current rankings. Use a rank tracker for that.
