What Is Ahrefs?
Developed by Ahrefs, the platform runs one of the most active web crawlers outside of the major search engines, which is why its link and keyword data is considered among the most reliable available. Whether you are launching a new site or managing an enterprise project, Ahrefs gives you the competitive intelligence to make confident decisions.
Site Explorer
Site Explorer lets you analyze any website’s organic traffic, ranking keywords, top pages, backlink profile, and paid search activity. Plug in a competitor and you instantly see where their traffic comes from, which is the foundation of the workflow in our guide to competitor keyword analysis.
Backlink Analysis
Ahrefs is best known for its backlink database, one of the largest and most frequently updated in the industry. You can examine referring domains, anchor text, new and lost links, Domain Rating (DR), and link growth over time, and use the Link Intersect report to find sites linking to competitors but not to you. To act on that data, see our guides on how to earn backlinks organically and digital PR for SEO.
Keywords Explorer
Keywords Explorer covers Google, Bing, YouTube, Amazon, and other search engines with search volume, keyword difficulty, traffic potential, click metrics, and search intent, plus thousands of related suggestions. Our guide on how to do keyword research shows how to turn those reports into a content plan.
Rank Tracker
Rank Tracker monitors keyword positions over time with visibility, average position, traffic estimates, SERP features, and competitor comparisons, so you can measure progress and react to fluctuations. Our explainer on how Google core updates affect rankings pairs well with this data.
Site Audit
Site Audit crawls your website and flags technical issues such as broken links, duplicate content, missing meta tags, redirect chains, slow pages, and crawl errors, each with a health score and fix guidance. Combine it with our technical SEO checklist for a full audit process.
Content Explorer
Content Explorer searches a huge index of web pages by topic and filters by traffic, backlinks, shares, and publish date so you can find proven content ideas and link-worthy formats in any niche. It is a great input for the strategy we outline in building topical authority.
