Definition
Barnacle SEO (named after the shellfish that attaches to rocks and boats) is a strategy of creating optimized profiles and content on high-authority platforms to appear in search results. Unlike parasite SEO which primarily aims at ranking, barnacle SEO focuses on maximum SERP occupation: Google Business listing, Yelp profiles, LinkedIn, Facebook pages, Quora answers, Medium articles, etc. The goal is to dominate the first page by multiplying presence across different platforms for the same query, especially for brand queries or highly competitive local queries.
Key Points
- Multiply presence on high-authority platforms
- Particularly effective for local and brand queries
- Push down negative results by occupying the SERP
Practical Examples
Local SERP domination
A restaurant creates optimized profiles on Google Business, TripAdvisor, Yelp, Yellow Pages, Facebook, and TheFork. For the query 'Italian restaurant Lyon', it appears 4 times on the first page.
Brand strategy
A company optimizes its LinkedIn profile, Facebook page, YouTube channel, and Google listing to control first-page results when someone searches its name.
