What’s New for Both Tools in 2025

Before we get into the nitty-gritty comparison, let’s quickly touch on what’s changed this year. Both Semrush and Ahrefs have been busy adding new features and refining their platforms.

Semrush has doubled down on its AI capabilities, expanding their ContentShake AI tool and introducing more advanced traffic analytics. They’ve also enhanced their backlink database, now boasting over 43 trillion backlinks. That’s impressive growth from previous years.

Ahrefs hasn’t been sitting still either. They’ve expanded their multi-search engine tracking capabilities, refined their AI Content Helper, and continued to build out their keyword database, which now contains over 28.7 billion keywords. They’ve also made significant improvements to their SERP feature tracking.

Both tools are evolving – but let’s see how they stack up against each other in 2025.

Ease of Use & Interface

When you’re investing in an SEO tool, you want something powerful but also intuitive. After all, what good are advanced features if you can’t figure out how to use them?

Ahrefs: Clean, Intuitive, and Beginner-Friendly

Ahrefs has always been known for its clean, intuitive interface, and this remains true in 2025. The dashboard gives you a quick overview of your projects, with the main navigation menu providing easy access to all tools.

What makes Ahrefs particularly user-friendly is the logical flow between tools. For example, you can seamlessly move from keyword research to content analysis to backlink checking, with each step feeling natural and connected.

New users will appreciate how quickly they can get up to speed. The learning curve is relatively gentle, with helpful tooltips and clear explanations throughout the platform.

Semrush: Comprehensive but Potentially Overwhelming

Semrush offers an incredibly comprehensive suite of tools – over 55 at last count. This is both a strength and a potential weakness when it comes to usability.

The sheer number of features can make the interface feel cluttered and overwhelming for newcomers. However, Semrush has made significant improvements to their feature categorization in recent updates, making it easier to find what you need.

The dashboard is highly customizable, allowing you to prioritize the tools and metrics that matter most to you. Once you’ve spent some time with the platform and set it up to your liking, it becomes much more manageable.

Pro tip: If you’re new to Semrush, start by focusing on 2-3 core tools rather than trying to master everything at once. The platform rewards those who take the time to learn its ins and outs.

Features & Tools Comparison

This is where the rubber meets the road – what can each platform actually do for your SEO efforts?

Semrush: The All-In-One Digital Marketing Suite

Ahrefs: SEO-Focused with Powerful Core Tools

Ahrefs takes a more focused approach, concentrating primarily on core SEO functionalities with about 20 tools. They’ve chosen to do fewer things but do them exceptionally well.

Keyword Research Capabilities

Keyword research is the foundation of any successful SEO strategy. Let’s see how these tools stack up.

Semrush: Comprehensive Data with Marketing Context

Semrush’s keyword database contains over 26.4 billion keywords, providing extensive coverage across multiple languages and regions.

Their Keyword Magic Tool offers:

• Keyword difficulty scores
• Search volume trends
• Keyword intent analysis
• Question-based keyword suggestions
• SERP feature analysis

What makes Semrush’s keyword research particularly valuable is the marketing context it provides. Beyond just search volumes and difficulty scores, you get insights into the competitive landscape, potential traffic, and even content recommendations based on your keyword targets.

The Keyword Gap tool is excellent for identifying opportunities your competitors are targeting but you’re missing.

Ahrefs: Depth, Accuracy, and Actionable Metrics

Ahrefs boasts an impressive 28.7 billion keywords in their database, slightly edging out Semrush in raw numbers.

Their Keywords Explorer provides:

• Keyword difficulty scores
• Click metrics (clicks per search)
• Parent topic identification
• SERP overview and position history
• Keyword ideas and questions

What sets Ahrefs apart is their clicks data. Instead of just showing search volume, they estimate how many clicks a keyword actually generates – accounting for no-click searches, featured snippets, and other SERP features that might impact click-through rates.

This gives you a more realistic picture of a keyword’s traffic potential. After all, what matters isn’t just how many people search for a term, but how many actually click through to websites.

Backlink Analysis

Backlinks remain a crucial ranking factor in 2025, making backlink analysis tools essential for any serious SEO strategy.

Semrush: Massive Database with Detailed Metrics

Semrush has dramatically expanded its backlink database in recent years, now indexing over 43 trillion backlinks. This represents one of the largest link databases in the industry.

Key features of their backlink analysis tools include:

• Backlink Analytics: Provides comprehensive backlink profiles for any domain.
• Backlink Audit: Identifies toxic links that might harm your site.
• Link Building Tool: Helps you find and track link building opportunities.
• Bulk Analysis: Allows you to compare multiple domains at once.

The Backlink Gap tool is particularly useful, showing you which sites link to your competitors but not to you – essentially a ready-made list of link building targets.

Ahrefs: Quality Over Quantity with Intuitive Analysis

Ahrefs’ backlink database contains over 14 trillion backlinks – smaller than Semrush’s but still massive by any standard.

Despite the smaller raw number, many SEO professionals still prefer Ahrefs for link analysis because of:

• Intuitive interface that makes link exploration easier
• Detailed link metrics including URL Rating (UR) and Domain Rating (DR)
• Historical backlink data to track link acquisition and loss over time
• Comprehensive broken link checker

The Best by Links report in Content Explorer is a standout feature, helping you identify the most linked-to content in your niche – perfect for creating link-worthy content of your own.

Pricing Comparison

Both tools represent a significant investment, so let’s break down the pricing structures to help you decide which offers better value for your specific needs.

Semrush: Premium Pricing with Extensive Features

Semrush offers three main pricing tiers:

All plans include core SEO tools, but higher tiers offer more features, higher limits, and access to advanced tools like historical data and content marketing analytics.

Semrush offers a 14-day free trial, giving you a chance to test the platform before committing.

Ahrefs: Focused Pricing with No Free Trial

Ahrefs has a similar tiered pricing structure:
