Google Search Console and Ahrefs Webmaster Tools (AWT) are the two best free SEO tools available — and people constantly ask which one to use.
The honest answer: they barely overlap. GSC is Google telling you how your site performs in Google. AWT is Ahrefs' crawler telling you what your site looks like from the outside — backlinks, technical issues, and competitive context. Most sites should run both.
Here's the breakdown.
The Core Difference
Google Search Console answers: What queries do I rank for, how often do people see and click my pages, and is Google having trouble indexing my site?
Ahrefs Webmaster Tools answers: Who links to my site, how healthy is my site technically, and how do I stack up against the keyword landscape?
GSC's data comes straight from Google's index — it's the only place to get your real impressions, clicks, and average positions. AWT's data comes from Ahrefs' own crawler and link index, which sees things Google won't show you (like most of your backlink profile).
Google Search Console: What It Does Well
Real query data, straight from Google
No third-party tool can tell you what you actually rank for with real impression and click counts. GSC can. The Performance report is the single most valuable free dataset in SEO — see our complete GSC guide for how to use it.
Index coverage and crawl diagnostics
If Google won't index your pages, nothing else matters. GSC's index coverage report and URL Inspection tool are the only authoritative sources on what Google has and hasn't indexed — and why.
Sitemap submission and manual actions
GSC is the only channel for submitting sitemaps to Google, and the only place you'll find out about manual actions before your traffic falls off a cliff.
Where GSC falls short
- Backlink data is thin — the links report shows a sample, not your full profile, with no quality metrics
- No technical site audit — GSC tells you what Google tripped over, not what's wrong before Google finds it
- 16 months of data history, then it's gone
- No competitive data at all
Ahrefs Webmaster Tools: What It Does Well
A real backlink profile
AWT gives you access to Ahrefs' link index for your verified sites — referring domains, anchor text, new and lost links, and domain-level metrics. This is dramatically more complete than GSC's links report and is the main reason to sign up.
Site Audit
AWT crawls your site like a search engine would and flags technical issues: broken links, redirect chains, missing meta tags, slow pages, duplicate content. GSC will never proactively give you this list.
Keyword context
AWT shows estimated search volumes and keyword difficulty for the queries you rank for — context that GSC's raw impression counts don't provide.
Where AWT falls short
- The free tier is limited to sites you verify, with usage caps on Site Audit crawls
- Position and traffic numbers are estimates from Ahrefs' index — your GSC numbers are the ground truth
- No indexing diagnostics — it can't tell you why Google hasn't indexed a page

The Real Answer: Use Both, Then Act on the Data
Verification takes five minutes each. Run both. The harder problem isn't collecting data — it's turning it into a to-do list.
That's the gap Search Console Tools fills: it connects to your GSC account and converts the raw data into ranked actions — striking-distance keywords to push onto page one, pages with CTR below benchmark that need title rewrites, cannibalization conflicts to consolidate, and pages stuck outside the index. It's completely free, like both tools above.
FAQ
Is Ahrefs Webmaster Tools really free?
Yes, for sites you own and verify. It's a limited version of Ahrefs' paid platform — you get backlink data and site audits for your own properties, not competitor research.
Can Ahrefs Webmaster Tools replace Google Search Console?
No. Only GSC has your real Google performance data, index coverage, and manual action notifications. AWT supplements GSC; it doesn't replace it.
Which should I set up first?
GSC — it's the ground truth, and you'll need it anyway to verify ownership and submit sitemaps. Add AWT for backlinks and technical audits, then layer a tool like Search Console Tools on top to turn the GSC data into actions.
