similarweb-backlinks

Backlink analytics from SimilarWeb: backlink summary with TLD/country distribution, top referring domains, and individual backlinks with source URLs, anchors, and domain/page scores.

Prerequisites

• Node.js 22+
• Chrome with remote debugging (only for auth)
• A SimilarWeb Pro account (logged in at pro.similarweb.com)

Setup

node similarweb-backlinks.mjs auth

Reuses session from similarweb-website if available.

Usage

# Backlink summary: total backlinks, TLD distribution, top countries
node similarweb-backlinks.mjs summary chatgpt.com

# Top referring domains by backlink count
node similarweb-backlinks.mjs domains chatgpt.com
node similarweb-backlinks.mjs domains shopify.com --count=50

# Individual backlinks with source URLs, anchors, domain/page scores
node similarweb-backlinks.mjs links chatgpt.com
node similarweb-backlinks.mjs links shopify.com --count=50 --sort=PageScore --duration=3m

How it works

1. auth -- Reuses the similarweb-website session if available, otherwise extracts cookies from Chrome.

2. summary -- Calls GET /api/backlinks/summary. Returns total backlinks count, top TLD distribution (.com, .co.uk, .ai, etc. with counts and shares), and top referring countries.

3. domains -- Calls POST /api/backlinks/refdomains. Returns referring domains ranked by backlink count, with: domain name, global rank, backlinks count, referring pages, follow/nofollow breakdown, and first seen date. Sortable by BacklinksCount or Rank.

4. links -- Calls POST /api/backlinks/backlinks. Returns individual backlinks with: source URL, target URL, anchor text, page title, domain score (0-100), page score (0-100), source rank, first seen/last visited dates, and flags for new/lost/broken/image links. Sortable by DomainScore, PageScore, or Rank. Filterable by duration (28d, 3m, 6m, 13m).
