Is Ahrefs or Semrush better for backlink analysis?

For backlinks specifically, Ahrefs has the edge, with the freshest link index and the clearest new-vs-lost view in the industry. Semrush is the stronger all-round suite if you also want keyword, ad, and content tools in one place. If backlinks are the main event, pick Ahrefs; if you want one calmer tool for everything, pick Semrush.

How much do Semrush and Ahrefs cost?

Both start around $129 to $139 per month for their entry plans, billed monthly, with discounts for annual billing. Higher tiers with more usage, users, and historical data run several hundred dollars a month. For occasional competitor checks, that's a lot of money for capacity you won't use.

Do I need Semrush or Ahrefs to see a competitor's backlinks?

No. For checking a handful of competitors a month, a free backlink checker plus a spreadsheet answers "where do their best links come from?" perfectly well. Semrush and Ahrefs earn their price when you need daily monitoring, years of history, or to process hundreds of domains at once.

Which is easier to learn, Semrush or Ahrefs?

Semrush tends to feel gentler and more guided for newcomers, while Ahrefs is denser and more powerful once you climb the learning curve. If you value hand-holding, start with Semrush; if you want raw link intelligence and don't mind a steeper start, Ahrefs rewards it.

Comparison

Semrush vs Ahrefs for competitor backlinks

Two heavyweight SEO suites, one practical question. Which one actually helps you understand a competitor's links faster? An honest, hands-on comparison, with a straight answer on when neither is worth it yet.

Brad Williams·Updated Jul 2026·2 min read

If you've spent more than a week researching SEO tools, you've hit the same wall everyone does: Semrush and Ahrefs both look incredible, both cost real money, and both bury the one thing you came for under a hundred things you didn't. This is a comparison for the specific job of understanding a competitor's backlink profile, not an all-in-one SEO showdown.

What this means

Both tools are excellent. The right answer depends on how you think and what you'll actually use, not on whichever review site earns the bigger affiliate commission this month.

The short version

	Semrush	Ahrefs
Backlink index size	Very large	Largest, freshest
Ease of first read	Gentler, more guided	Denser, more powerful
"New vs lost" clarity	Good	Excellent
Anchor-text analysis	Good	Excellent
Learning curve	Moderate	Steeper
Entry price	~$139/mo	~$129/mo

Where Ahrefs wins

Ahrefs was built around links first, everything else second. Its backlink index is the freshest of the two, and the new vs. lost view is the clearest in the industry. If your whole job is link intelligence, Ahrefs will feel purpose-built.

Ahrefs is the sharper scalpel. Semrush is the friendlier cockpit. Neither is wrong. They just reward different temperaments.

Where Semrush wins

Semrush spreads wider, covering keyword research, ads, content, and backlinks under one roof. If you want your backlink work to sit next to everything else you do, and you value guidance over raw density, Semrush is the calmer place to start.

The honest third option

Here's the thing neither company will tell you: if you're checking a few competitors a month, you don't need either yet.

Buy Semrush or Ahrefs when you hit a concrete wall: you need daily monitoring, years of history, or to process hundreds of domains at once. Until then, a free checker plus a spreadsheet answers "where do their best links come from?" just fine.

Our take

Pick Ahrefs if backlinks are the main event and you like power tools. Pick Semrush if you want one calmer suite for everything. Pick neither yet if you're still doing this a few times a month. Start free and upgrade with a reason.
