How Accurate is Semrush?
Semrush is widely known for its perfect set of tools and accurate results. That’s why they have over 7 million users across the globe. So let’s check out the accuracy of Semrush’s widely-used tools and find out why it is so popular among SEO experts and digital marketers.
1. Keyword Research
Semrush’s keyword research capabilities are powered by its keyword database of over 25 billion keywords. This extensive database allows Semrush to provide insightful keyword data, including monthly searches, competition levels, and keyword ideas.
But how accurate is this data?
Several studies have found Semrush’s keyword data to match search volumes reported in Google Ads closely. When comparing monthly search volumes, Semrush’s estimates were, on average, within 6% of Google Ads numbers based on a sample of over 300 keywords. This indicates Semrush’s keyword data is reasonably accurate, although Google Ads should be considered the source of truth.
When looking at keyword difficulty scores and competition levels, Semrush uses a proprietary algorithm incorporating ranking domains, paid difficulty, and other factors. Semrush’s difficulty scores typically align with manual assessments of competition. However, accuracy can vary significantly for low-traffic long-tail keywords that are difficult to measure.
Did You Know? Semrush is one of the leading keyword research tools that can even generate keyword ideas by entering a seed keyword.
2. Site Audit
Semrush’s site audit tool provides extensive details on a website’s technical SEO, on-page optimization, link profile, and more. This data powers its recommendations for improvements.
Studies evaluating the accuracy of Semrush’s site audits found its technical recommendations, such as fixes for crawl errors, redirects, and structured data, were over 90% accurate.
However, some issues, like duplicate meta descriptions, were incorrectly flagged over 50% of the time. Page-level optimization checks like reading level, headlines, and image alt-text were also accurate at least 80% of the time. However, Semrush’s assessments of content quality and depth were more subjective and inconsistent.
For backlink analysis, Semrush was able to identify 75-85% of a site’s backlinks when compared to other tools. However, it occasionally missed recently acquired links, and its link judgment (positive/negative) was not always aligned with manual checks.
3. Rank Tracking
Semrush’s rank tracking allows users to monitor website rankings for important keywords. But due to search engine personalization and localization, rankings can vary significantly based on user location and behavior. So how does Semrush’s rank data compare?
When benchmarked against other rank trackers, Semrush’s rankings were relatively accurate for national-level keywords, usually matching within 1-2 spots of major competitors. However, for more localized or personalized results, Semrush’s ranks diverged further from actual user-level ranks.
Some studies found Semrush’s ranks differed from real Google ranks by 5 positions or more for 40% of keywords when comparing side-by-side with localized accounts. This suggests Semrush’s rank data is best interpreted as a general guideline, not an exact measure for geo-targeted or personalized keywords.
Having access to rank tracking for 9 global markets is valuable. But users should always test important keyword ranks manually in relevant locations when accuracy is critical. Here is a comprehensive guide to track search engine rankings.
4. Competitive Research
From organic research to PPC ads to SEO content, Semrush offers expansive competitive intelligence options.
For organic keyword tracking, Semrush’s limitations in rank accuracy also apply to its competitor tracking. Semrush can identify 90% or more of a competitor’s ranking keywords, but ranks are best considered directional.
Paid keyword tracking is typically more accurate, with around 80% match rates against Google Ads when sampled.
For ad copy and landing page research, Semrush excels at revealing a wide footprint of a competitor’s ads and pages. However, aggregating ad copy from multiple sources can result in mismatching ad headlines and bodies in its database. Manually reviewing full ads is still required for accuracy.
Semrush’s competitor content analysis identifies relevant pages and topics covered by rivals. But the technology for analyzing on-page content accuracy is still developing. Hotjar or direct content checks yield more precise topic insights currently.

5. Advertising Research
Semrush’s advertising research tools offer insights into ad strategies used by competitors. It allows users to see which ads are currently running and even how much their competitors are spending on ads.
Studies have found that Semrush’s advertising research data is mostly accurate, with around 90% accuracy in identifying ad campaigns. However, users should keep in mind that ad data is constantly changing, and some ads may not be visible at all times.
6. Social Media Tool
Semrush offers a social media tool that allows users to track social media engagement and analyze their competitors’ social media presence. While this tool is helpful for social media marketing, its accuracy is limited.
The tool’s social media analytics, such as follower count and engagement rate, are typically accurate. Still, it doesn’t provide information on social media advertising, and its data on competitors’ social media activity may be incomplete.

- SERPstat offers more flexible rank filtering options (e.g. device, location) and graph types for visualizing trends.
- For rank tracking, SERPstat is likely more accurate for highly localized keywords. But for broad national tracking, the two are nearly equal.
