Ahrefs
SEO research platform that crawls the web to show you what keywords competitors rank for, where their backlinks come from, and how to outrank them.
What are Ahrefs?
Ahrefs is an SEO research platform that crawls 6 billion web pages daily to give you competitive intelligence on keywords, backlinks, and content performance.
It runs the second most active web crawler after Google, which means it has one of the largest databases of backlinks and keyword data in the industry.
Most builders use it to spy on competitors (what keywords they rank for, where their traffic comes from), find content gaps in their niche, and track their own site's SEO health. The Site Explorer tool is particularly useful for reverse-engineering how top-ranking sites got there.
Plans start at $29/month for basic keyword research, scaling up to $1,499/month for agencies. There's also a free Webmaster Tools version if you just want to audit your own site.
