Keyword Zebra

Keyword Zebra is a Chrome extension that overlays domain age on Google SERPs to help SEOs find newly created, low-authority sites ranking for target keywords — useful for spotting easy-to-rank terms, cheap guest post targets, and parasite SEO opportunities.

What is Keyword Zebra?

Keyword Zebra is a focused SEO Chrome extension that takes a unique approach to competitive analysis: instead of showing search volume or backlink counts, it overlays domain age directly onto Google search results. The core idea is that if many newly created websites (under your chosen age threshold) are ranking for a keyword, that keyword is likely easier to rank for — and those young sites are potential guest post targets, client prospects, or content gap opportunities. The extension scans the top 100 results, filters by age, and lets you export the qualifying domains with one click. It also flags parasite SEO pages — low-quality content riding on authority domains. While the concept is genuinely useful for niche site builders and link builders, the tool is extremely narrow in scope, the Chrome Web Store listing was removed in February 2025, and independent reviews are scarce. At $19 for lifetime access via DealFuel, it's cheap enough to experiment with, but don't expect it to replace your full SEO stack.

Key Features

• SERP Domain Age Overlay — instantly see how old each ranking site is directly in Google results
• Age-Based Filtering — set a threshold (e.g. under 3 years) to surface only young, low-authority competitors
• One-Click Competitor Export — collect all qualifying domains from a SERP into a list for outreach
• Parasite SEO Detection — identify pages from low-quality or off-topic sites riding authority domain rankings
• Keyword Difficulty Proxy — many new sites ranking suggests the keyword may be easier to target
• Link Building Prospect Finder — young sites tend to sell guest posts and niche edits cheaply
• Client Prospecting — find newly ranking websites that likely need SEO help you can sell them
• Content Gap Analysis — extract keywords from young competitors' sites to find stealing opportunities
