3. SEMrush vs Ahrefs: Feature-by-Feature Breakdown
Here’s a complete, detailed feature-by-feature breakdown of SEMrush vs Ahrefs, so you can clearly see where each tool shines — and which one might be the best fit for your SEO or digital marketing needs.
Keyword Research (Who Finds Better Keywords?)
Keyword research is the foundational process in search engine optimization (SEO) where you discover and analyze the actual words and phrases that people enter into search engines when looking for information, products, or services. The goal is to understand what your target audience is searching for online so you can create content that answers their questions, solves their problems, or matches their intent.
At its core, keyword research is about aligning your content with the real language of your audience. When you identify the right keywords, you’re not just guessing at what people might be interested in—you’re basing your strategy on real data. This makes your website or content more visible in search engine results pages (SERPs), which leads to more organic traffic and, ultimately, more engagement, leads, or sales.
The process involves several layers. It starts with brainstorming general topics relevant to your business, then diving deeper into specific search terms related to those topics
| Feature | SEMrush | Ahrefs |
|---|---|---|
| Keyword Database Size | 25B+ keywords | 10B+ keywords |
| Keyword Difficulty (KD) | 0-100 scale | 0-100 scale |
| Search Volume Accuracy | Good | More accurate |
| Long-Tail Keywords | Excellent (more variations) | Good |
| Local SEO Keywords | Strong (local pack tracking) | Weak |
| Keyword Suggestions | Questions, related terms, modifiers | Mostly standard variations |
| Historical Data | 12 months | 24 months |
WINNER: SEMrush (better for local SEO, long-tail keywords, and content ideas)
Why?
- SEMrush’s Keyword Magic Tool generates 1,000+ keyword ideas in seconds.
- Ahrefs’ Keywords Explorer is great but lacks local SEO features.
Backlink Analysis (Who Has the Best Link Data?)
Backlink analysis is the process of examining the inbound links (also called backlinks) that point to a website from other websites. These links are a crucial part of SEO because search engines like Google view them as votes of confidence — the more high-quality, relevant backlinks a website has, the more trustworthy and authoritative it appears in the eyes of search engines.
When performing backlink analysis, you’re essentially evaluating who is linking to your site, what pages they’re linking to, the quality and authority of those linking sites, the types of links (dofollow or nofollow), and the anchor text used in the link. You can also identify how your backlink profile compares to your competitors, spot potentially harmful or spammy links, and discover opportunities to earn new, valuable backlinks.
| Feature | SEMrush | Ahrefs |
|---|---|---|
| Backlink Index Size | 45T+ links | 250T+ links |
| Referring Domains Data | Good | Best in class |
| Link Intersect (Competitor Comparison) | Yes | Yes |
| New/Lost Backlinks Tracking | Yes | More detailed |
| Anchors & Link Quality Analysis | Basic | Advanced |
| Spam Score Detection | Yes (Toxic Score) | No |
Winner: Ahrefs (largest database, better tracking, more accurate)
Why?
- Ahrefs updates its backlink index every 15 minutes (SEMrush takes longer).
- SEMrush’s Backlink Audit Tool is useful but not as deep.
Site Audit & Technical SEO (Who Crawls Better?)
Site Audit & Technical SEO refers to the process of evaluating and optimizing the technical aspects of a website to ensure it can be effectively crawled, indexed, and ranked by search engines. While content and backlinks are vital for SEO success, technical SEO lays the foundation that allows search engines to access, understand, and rank your site properly.
A site audit is essentially a full diagnostic checkup of your website. It scans for technical issues that could negatively impact your visibility in search results — such as broken links, slow page speed, missing meta tags, duplicate content, crawl errors, mobile usability issues, and problems with website structure. The goal is to uncover and fix these issues so that your site performs smoothly for both users and search engines.
Technical SEO focuses on behind-the-scenes optimizations, such as improving site speed, securing the site with HTTPS, ensuring a mobile-friendly design, fixing crawlability and indexability problems, optimizing URL structures, creating XML sitemaps, and managing redirects. It also includes implementing structured data (schema markup) to help search engines better understand your content.
Together, site audit and technical SEO form a crucial part of a successful SEO strategy. Without a technically sound website, even the best content and backlinks may not be enough to achieve high rankings. Conducting regular site audits ensures your site stays healthy, accessible, and optimized — giving your content the best possible chance to succeed in search results.
| Feature | SEMrush | Ahrefs |
|---|---|---|
| Crawl Limit | Up to 100,000 pages | Up to 500,000 pages |
| Issue Detection | 140+ checks | 100+ checks |
| Visual Reports | Yes | Yes |
| Fix Recommendations | Detailed | Detailed |
| Historical Data | Limited | Yes (track changes over time) |
Winner: Tie (SEMrush has more checks, Ahrefs allows bigger crawls)
Why?
- SEMrush’s Site Audit is great for smaller sites.
- Ahrefs’ Site Explorer is better for large websites (e.g., eCommerce).
Rank Tracking (Who Tracks Rankings Better?)
Rank tracking is the process of monitoring how well your website’s pages rank in search engine results for specific keywords over time. It helps you understand where your website appears on search engines like Google or Bing when users search for terms related to your business, content, or products.
By tracking keyword rankings, you can measure the effectiveness of your SEO strategy and see whether your efforts are leading to higher visibility. For example, if you optimize a blog post for the keyword “best running shoes,” rank tracking tools will show you whether your post is climbing up in the search results for that phrase — or if it’s dropping.
Rank tracking isn’t just about knowing your current position. It reveals trends, helps spot problems (like sudden ranking drops), and allows you to track performance across different locations, devices (desktop vs. mobile), and even search engines.
Overall, rank tracking gives you a clear view of how your website is performing in organic search. It’s essential for SEO professionals, marketers, and business owners who want to stay competitive and continuously improve their online presence.
| Feature | SEMrush | Ahrefs |
|---|---|---|
| Keyword Tracking Limit | 500-5,000 (plan-based) | 500-10,000 (plan-based) |
| Local Rank Tracking | Yes | No |
| Mobile vs. Desktop Rankings | Yes | No |
| SERP Features Tracking | Yes (Featured Snippets, etc.) | Basic |
| Historical Data | 12 months | 24 months |
Winner: SEMrush (better for local & mobile rankings)
Why?
- SEMrush tracks Google My Business rankings (Ahrefs doesn’t).
- Ahrefs has longer historical data (24 months vs. 12).
Content & On-Page SEO (Who Optimizes Better?)
Content & On-Page SEO is all about making sure the words, structure, and design of a webpage are optimized so that both search engines and real people can easily understand, navigate, and engage with it.
At the heart of this is content — the actual information on your page, like blog posts, product descriptions, or service pages. Good content answers questions, solves problems, or delivers value to the reader. But for that content to show up in search results, it needs to be properly optimized, and that’s where on-page SEO comes in.
On-page SEO refers to all the elements you can control on the page itself to help it rank better. It also involves making sure your content is easy to read, mobile-friendly, and fast-loading — all of which are ranking factors.
In short, content and on-page SEO work hand-in-hand. You can think of content as the message, and on-page SEO as the way you package that message so it gets noticed, ranked, and clicked. When done right, this combo brings in more traffic, keeps users engaged, and helps your site compete in search results.
| Feature | SEMrush | Ahrefs |
|---|---|---|
| Content Optimization | Yes (SEO Writing Assistant) | Yes (Content Gap tool) |
| Plagiarism Checker | Yes | No |
| Readability Score | Yes | No |
| Content Gap Analysis | Yes | More advanced |
| AI Content Tools | Yes (SEO Content Template) | No |
Winner: SEMrush (better for writing & optimizing content)
Why?
- SEMrush’s SEO Writing Assistant helps write SEO-friendly content.
- Ahrefs’ Content Gap tool is great but lacks writing aids.
