Linkwake vs Semrush

Linkwake tracks changes in referring domains across agency client portfolios. It compares Common Crawl releases to show domains gained, lost or retained, and identifies domains linking to competitors but not to a tracked site as possible outreach gaps. Users can organize domains into portfolios, follow movement on dashboards, and receive scheduled weekly or monthly CSVs or shareable client report links. Its source is Common Crawl’s web graph, which Linkwake says covers more than 100 million domains; data changes when releases arrive, roughly every 2–3 months. The focus is domain-level links, not keywords, page-level links or anchor text. The free plan costs nothing and includes five tracked domains, release-change comparisons, email digests and manual reports. Paid plans start at $24/mo. Starter lists 100 domains and three releases of history; higher plans offer more tracked domains, longer history, reports and API access. Common Crawl is not a complete web index, so missing relationships should be checked before outreach.
