Ahrefs
The complete SEO and AI marketing suite
What is Ahrefs?
Ahrefs has long been the gold standard for SEO professionals, and its recent AI-powered evolution cements that reputation. Built on one of the world's largest web crawlers—ranked #34 on the TOP500 supercomputer list—Ahrefs processes billions of pages to deliver real-time insights that actually move the needle. The headline addition is Agent A, an AI marketing assistant with unrestricted access to Ahrefs' massive crawl database. Unlike typical AI chatbots that rely on static training data, Agent A can pull live backlink profiles, keyword rankings, and site audit data on demand. It supports multiple AI models including Claude and Gemini, giving you flexibility in how tasks get executed. But Ahrefs isn't just about the AI gimmick. The core toolkit remains best-in-class. Site Explorer lets you dissect any domain's backlink profile and organic traffic. Keywords Explorer helps you discover high-opportunity terms with clustering and intent filtering. The Site Audit tool crawls your entire site and flags technical issues, with automated fixes available for common problems. Newer additions like Brand Radar track your brand mentions and sentiment across AI search responses and social channels. The Social Media Manager (still in beta) lets you schedule posts and monitor engagement. For local businesses, the GBP Monitor tracks Google Business Profile performance. Pricing ranges from a limited free plan to the Starter plan at $29 per month for solo operators, scaling up to Enterprise at $1,499 per month with uncapped API access. It is not cheap, but for serious SEO work, Ahrefs delivers unmatched data depth. If you are serious about search engine optimization—whether you are a freelancer, agency, or Fortune 500 team—Ahrefs is the most comprehensive and trustworthy platform available today.
How to Use Ahrefs
Ahrefs Site Audit is a powerful tool that crawls your entire website and identifies technical SEO issues that could be hurting your search rankings. Follow these steps to run a comprehensive audit and automatically fix the most common problems.
Create a New Site Audit Project
Navigate to the Site Audit tool from your Ahrefs dashboard and click 'New Project'. Enter your website URL, configure crawl settings such as crawl speed and user agent, then click 'Start Audit' to begin the initial crawl of your entire site.
Review the Overall Health Score
Once the crawl completes, review the Site Audit Overview dashboard which displays your overall health score, total pages crawled, and a breakdown of issues by severity including errors, warnings, and notices. Focus on errors first as they require immediate attention.
Analyze Technical Issues by Category
Click into each issue category to see detailed reports grouped by type such as internal pages, HTML tags, links, images, and performance. Each issue includes a description of the problem, affected pages, and recommended fixes with documentation links.
Apply Automatic Fixes
For many common technical SEO issues, Ahrefs offers one-click automatic fixes directly within the issue details. Look for the 'Auto-fix' option which can resolve problems like missing meta descriptions, duplicate title tags, and broken internal links without developer intervention.
Schedule Ongoing Monitoring
Set up recurring automated crawls in the project settings to continuously monitor your site's health. Enable email alerts for new critical issues that appear between scheduled audits, and track your health score improvement over time in the dashboard.
