Ahrefs Site Audit is part of a $99/month SEO suite built around backlink data and site-wide crawling. SilverGecko is a free, focused tool for page-level SEO audits with AI-era checks. They solve different problems.
What Ahrefs does better
Site-wide crawling
Ahrefs crawls your entire site and finds issues across thousands of pages at once. Broken links, redirect chains, orphan pages, duplicate content across pages. SilverGecko audits one page at a time.
Backlink analysis
Ahrefs has one of the largest backlink indexes. Link intersect, referring domains, anchor text distribution. SilverGecko has no backlink data.
Keyword research
Ahrefs includes keyword explorer, content gap analysis, and SERP history. SilverGecko doesn't do keyword research.
Historical data
Ahrefs tracks your site's performance over months and years with position tracking. SilverGecko tracks audit scores over time but doesn't track keyword positions.
What SilverGecko does better
AI visibility checks
SilverGecko audits your page for AI search readiness. LLM citation signals, content structure for AI extraction, FAQ schema for AI Overviews. Ahrefs doesn't have AI-specific checks.
E-E-A-T analysis
SilverGecko checks for author credentials, experience signals, trust pages, and YMYL detection. Ahrefs checks technical signals but doesn't evaluate E-E-A-T compliance.
Content quality scoring
The fluff detector catches AI-generated patterns (60+ phrases), filler content, and passive voice. This matters after Google's December 2025 update penalized low-quality AI content.
Free with no limits
Every SilverGecko tool works without signup or payment. Unlimited audits. Ahrefs starts at $99/month with crawl limits on lower tiers.
pSEO workflow
SilverGecko includes a full programmatic SEO pipeline: analyze opportunities, generate strategies, launch campaigns, batch-create pages. Ahrefs doesn't have pSEO tooling.
When to use Ahrefs
- You need to crawl an entire site (hundreds or thousands of pages)

Using both together
Many SEO professionals use both. Ahrefs for site-wide crawling, backlink research, and keyword tracking. SilverGecko for page-level AI visibility checks, content quality scoring, and pSEO workflows. They complement each other rather than compete directly.
