This index powers tools that provide insights into SEO performance, competitive analysis, and technical website health.
The platform organizes this data within tools such as Site Explorer, Keywords Explorer, and Site Audit. These tools evaluate backlink profiles, keyword rankings, and crawl issues. Ahrefs bases its insights on its own crawl scope and estimation models, which update slower than real-time changes or omit trends in smaller or regional markets.

Semrush excels in broad keyword discovery by grouping terms by topic and search intent, using filters and CPC data to target long-tail keywords and plan SEO and PPC campaigns precisely. Ahrefs prioritizes keyword difficulty and traffic potential based on backlink profiles, offering a backlink-driven view that supports competitive insights rather than keyword discovery.
Why is Search Volume so different on Ahrefs Compared to Semrush?
Search volume differs between Ahrefs and Semrush because each platform uses unique data sources, collection methods, and estimation models. Its differences in input data and processing explain why the same keyword displays different search volumes across both platforms.

Why is Keyword Difficulty Calculation so different on Semrush Compared to Ahrefs?
Keyword difficulty (KD) calculation is different on Semrush compared to Ahrefs because each platform uses a unique scoring method and factor weighting.
Ahrefs calculates KD mainly from the number of referring domains to the top 10 ranking pages. It counts backlinks to these pages, with more links indicating higher difficulty. Semrush uses a broader formula that combines multiple ranking signals, which includes referring domains, dofollow/nofollow ratios, domain authority scores, and SERP-specific features.
This difference means Ahrefs provides a backlink-focused difficulty score, while Semrush gives a multi-factor difficulty score influenced by both link profiles and keyword-specific search characteristics.

Semrush offers a full content optimization suite with Topic Research to uncover popular ideas, SEO Content Template to generate SEO briefs, and the SEO Writing Assistant to suggest related terms and flag errors, which helps align content with search intent and brand style during writing. Some suggestions require manual adjustment for natural flow.
The Ahrefs Content Explorer analyzes top pages for backlinks, traffic, and shares. Its AI Content Helper compares your content to competitors, identifies key topics, and spots gaps to improve rankings. While providing strong data-driven insight, it lacks real-time editing feedback
Why is real-time content scoring so different on Ahrefs compared to Semrush?
Real-time content scoring differs between Ahrefs and Semrush because their systems measure different elements and aim for different optimization goals.
Ahrefs evaluates topical coverage by comparing your draft to top-ranking pages. It scores how well your content covers relevant subtopics. The score updates instantly with edits and focuses on content completeness rather than style.
Semrush uses multiple factors such as keyword placement, tone, and originality. It provides a dynamic, composite score with detailed guidance on specific issues as you write. This broader scoring supports holistic optimization but makes scores less comparable to top-ranking pages.
Why is content gap identification so different on Ahrefs compared to Semrush?

The Ahrefs Content Gap tool performs ranking-based domain comparisons. It identifies keywords competitors rank for but your site lacks and enables side-by-side analysis of multiple domains. This approach builds topical authority and highlights c
lusters of missing keywords within a niche.

It tracks desktop and mobile results at precise locations daily, which includes SERP features and competitor moves. This suits multi-platform, local, and mobile-first campaigns requiring detailed visibility and swift response.

Why is share of voice calculation so different on Semrush Compared to Ahrefs?
Share of voice (SOV) is calculated differently on Semrush compared to Ahrefs because each platform uses distinct definitions, keyword sets, and traffic estimation models.
Ahrefs calculates share of voice by estimating the percentage of total clicks your tracked keywords receive compared to competitors. It uses its keyword database, CTR models, and position tracking, so results depend heavily on chosen keywords and Ahrefs’ click-through rate assumptions.
Semrush calculates share of voice by dividing estimated traffic from tracked keywords by the combined search volume of those keywords. It focuses on traffic share from rankings, relying on keyword data, search volume, and traffic potential models, which reduces varying results based on search volume weighting.
The difference is significant because Ahrefs prioritizes click share while Semrush prioritizes traffic share from volume estimates.
Ahrefs vs. Semrush: Which SEO Tool Is Better for Customer Support?
Semrush and Ahrefs are tied for customer support because each offers advantages that balance the other gaps. Semrush support options suit users who value more customer support options, while Ahrefs appeals to those who prefer immediate human interaction.
Semrush stands out for offering multiple contact channels, though free users often interact with a chatbot instead of a person.

What is the Key Difference between Semrush and Ahrefs?

Ahrefs or Semrush: Which SEO Tool Offers the Best Overall Value?
Neither Ahrefs nor Semrush offers the best overall value. Both platforms offer pricing models that are restrictive for many users. Subscription tiers often require additional spending on credits, add-ons, or expanded limits, which increases costs beyond the base plan.

Is It Worth Using Ahrefs and Semrush Together?
