When to use this skill

Use RankParse when the user is doing SEO work:

• Link building — finding prospects, auditing competitors' backlinks, spotting link gaps
• Competitor research — comparing DA scores, top pages, referring domains across sites
• Site audits — checking tech stack, page metadata, crawl history, status codes
• Content strategy — finding which pages earn the most links in a niche
• Prospecting — discovering similar domains or shared linkers for outreach lists

Common SEO workflows

Competitor link gap analysis

Find domains linking to competitors but not to you — ranked by authority for outreach prioritization.

1. get_backlinks for your domain
2. get_backlinks for each competitor
3. get_domain_overlap across all targets
4. get_domain_authority on gap domains to prioritize

Prompt: "Find link-building opportunities I'm missing vs stripe.com and shopify.com"

Domain authority comparison

Benchmark a site against competitors before a pitch, acquisition, or partnership.

1. get_domain_authority for each domain

Prompt: "Compare the DA of linear.app, height.app, and plane.so"

Backlink profile audit

Understand the quality and anchor text distribution of a site's inbound links.

1. get_referring_domains — unique linking domains
2. get_anchor_text — anchor text distribution, flag over-optimized anchors
3. get_backlinks — top individual links with source pages

Prompt: "Audit the backlink profile of example.com — flag anything that looks spammy"

Top pages by link equity

Find what content earns the most links in a niche to inform your content strategy.

1. get_top_pages for competitor domains

Prompt: "What pages on vercel.com attract the most backlinks?"

Outreach list building

Build a targeted list of prospects to contact for guest posts or link placements.

1. get_similar_domains — sites with overlapping link profiles
2. get_link_intersect — domains already linking to multiple competitors
3. get_domain_authority — filter by DA threshold

Prompt: "Build me a list of 20 sites similar to smashingmagazine.com with DA over 50"

Site technical audit

Quickly check a site's tech stack, page signals, and crawl health.

1. get_tech_stack — CMS, analytics, CDN, frameworks
2. get_page_meta — title, description, canonical, OG tags
3. get_crawl_history — first seen, last crawled

Prompt: "What tech stack and CMS is competitor.com running?"
