Ahrefs vs Semrush: which one should I use?

Updated April 19, 2026

Quick Answer

Both are excellent and the right choice depends on your priority. Ahrefs has the best backlink index and a cleaner interface for content gap analysis. Semrush has stronger competitive PPC research and a broader marketing toolkit (PR, content marketing, social). For most Toronto SEO use cases, either tool covers 90% of what you need. Pricing starts around $129 USD/month for both.

Where Ahrefs wins

Backlink data: Ahrefs has the largest live index of backlinks, with the most accurate freshness and link quality scoring.

Content gap analysis: cleaner workflow for finding keywords your competitors rank for that you don't.

Site Explorer: faster, cleaner interface for one-off competitive research sessions.

Webmaster Tools (free): limited free version for monitoring your own site's backlinks and basic SEO health.

Where Semrush wins

PPC and competitive ad research: see exactly what ads competitors are running and which keywords they're bidding on.

Broader marketing toolkit: PR research, social media tracking, content marketing platform integrated.

Local SEO features: better integrated local rank tracking and listing management built in.

Project management: more structured workflows for managing client accounts at agencies.

Do I need a rank tracking tool?

Yes — Search Console shows average position over a 28-day window which is too aggregated for tactical decisions. A dedicated rank tracker (Ahrefs, Semrush, AccuRanker, Wincher) shows daily ranking changes for your priority keywords across desktop and mobile, with location-specific tracking for Toronto neighbourhoods. Budget C$50–C$300/month depending on keyword volume.

Should I use call tracking for SEO?

Yes if phone calls drive significant revenue and you can't otherwise attribute them to source. Call tracking platforms (CallRail, WhatConverts, Phonexa) display unique phone numbers to different traffic sources, letting you see which calls came from organic search, which keywords triggered them, and which landing pages converted. Pricing typically runs C$50–C$300/month.
