What is SEOquake?

Do you know what is SEOQuake? SEOquake is a free and powerful browser extension developed by Semrush that provides real-time SEO metrics and insights for any web page or search engine results page (SERP). With over 3 million installs and counting, SEOquake is trusted by SEO professionals, digital marketers, and website owners who need quick access to a wide range of search engine optimization data directly within their browser.

Available for Chrome, Firefox, Opera, and Microsoft Edge, SEOquake enables users to evaluate on-page SEO, analyze backlinks, assess keyword density, and perform side-by-side comparisons of URLs or domains. Whether you’re auditing your own site or researching a competitor, SEOquake delivers crucial data with just a few clicks—no login required, and no need to leave the page you’re on.

Key Features of SEOquake

One of the primary reasons for SEOquake’s popularity is its extensive set of features. These tools are designed to assist marketers and SEO experts with fast, reliable, and actionable insights.

SEO Audit: SEOquake can perform a detailed on-page audit in seconds. It checks for common SEO issues such as missing meta descriptions, header tags, image alt attributes, mobile-friendliness, and page load speed. This feature is essential for identifying technical SEO flaws without having to use multiple tools.

SEO Bar and Dashboard: The SEO bar appears at the top of your browser when visiting a page and displays key SEO metrics such as Google index status, SEMrush ranking data, Alexa rank (now deprecated), backlinks, and more. The dashboard offers a more detailed, interactive overview of these metrics.

SERP Overlay: When you perform a Google search, SEOquake can overlay useful SEO statistics for each result, such as domain age, number of backlinks, and social signals. This is incredibly useful for competitor analysis, helping users understand why certain pages rank higher than others.

Link Analysis: SEOquake provides detailed insights into a page’s internal and external links. It categorizes links by type (follow/nofollow) and offers anchor text analysis. This is valuable for both link-building strategies and on-site SEO improvements.

Keyword Density Tool: This tool analyzes the page content and calculates how frequently each keyword appears, showing percentages for single words, two-word phrases, and three-word phrases. It helps avoid keyword stuffing while ensuring keyword optimization remains strong.

SEO Comparison (“SEO Showdown”): With SEOquake, users can compare multiple URLs or domains side by side. This feature presents comparative data such as backlink counts, domain age, and keyword density—ideal for competitive benchmarking.

Export Options: Data from the tool can be exported in CSV format or printed, making it easy to generate reports or share findings with team members or clients.

Benefits of Using SEOquake

SEOquake’s biggest advantage is how much value it offers for free. For marketers on a budget or those just starting out, it’s a feature-rich alternative to expensive platforms. It’s lightweight, easy to install, and does not require a user account for most of its functionality.

Users can access multiple data points—such as indexing information, backlink counts, and on-page SEO status—directly from the search results or any webpage. This saves time and simplifies the research process.

The extension is also highly customizable. You can choose which metrics to display, enable or disable features like the SEO bar or SERP overlay, and adjust delays for SERP analysis to improve performance.

Because SEOquake is backed by Semrush, one of the most reputable SEO platforms in the industry, it delivers reliable and accurate data integrated with a world-class SEO engine.

Things to Consider

While SEOquake is a powerful tool, it’s not without its drawbacks. Some users may find the interface a bit cluttered or dated, especially when multiple data panels are activated simultaneously. It takes a little configuration to make it more streamlined for everyday use.

Additionally, while many of SEOquake’s features are free, deeper insights such as backlink breakdowns or traffic analytics often require a connected Semrush account. For those who need enterprise-level data, SEOquake serves more as a gateway than a full-service platform.

Another concern for some users is the level of permissions required by the extension. Since SEOquake needs to read data on the websites you visit, it may raise privacy concerns. It’s important to review these permissions carefully during installation.

Lastly, some metrics once offered—like Alexa Rank—are now deprecated due to third-party data source changes. Although this doesn’t significantly affect the tool’s core functionality, it’s worth noting that not all legacy features are still in use.

How to Install and Use SEOquake

Getting started with SEOquake is simple. Visit your browser’s extension store—such as the Chrome Web Store or Firefox Add-ons—and search for “SEOquake.” Click “Add to Browser” and confirm the installation. Once installed, the SEOquake icon will appear in your browser’s toolbar.

When you visit a webpage, click the icon to launch the SEOquake dashboard. Here, you can view the SEO audit, analyze keyword density, inspect links, and see basic domain metrics. You can also customize which data points appear in your SEO bar and SERP overlay.

To use the SERP overlay feature, perform a search in Google. SEOquake will automatically append SEO metrics beneath each search result. You can adjust the number of results displayed, enable or disable data points, and export the entire list as a CSV for analysis.

The settings menu allows you to enable or disable specific features, change display preferences, and link your Semrush account for additional insights.

How SEOquake Fits into an SEO Workflow

SEOquake is not designed to replace full-fledged SEO suites but rather to complement them by speeding up the research and analysis process. It’s especially useful for:

Quick page audits to spot missing elements, slow load times, or meta tag issues.
Competitor analysis where you compare metrics like backlink count, page age, and domain authority.
Keyword research, thanks to the density tool and SERP overlay insights.
Link audits, which highlight internal and external links, link types, and anchor text patterns.
Client reporting, where exportable data makes it easy to create deliverables for stakeholders.

Whether you’re working solo, managing a team, or consulting for clients, SEOquake offers fast answers to common SEO questions—all from within your browser.

Alternatives to SEOquake

While SEOquake is a powerful all-rounder, there are other browser extensions and tools that might suit specific SEO needs better.

SEO Minion is a popular alternative that focuses on on-page SEO, broken link detection, and SERP preview features. It offers a clean interface and a solid set of features for day-to-day SEO work.

Detailed SEO Extension, MozBar, and SEO Meta in 1 Click are also frequently used for inspecting metadata, headings, and technical tags. These tools may offer less comprehensive data than SEOquake but excel in specific areas like meta tag validation or structured data checks.

Ultimately, the best tool depends on your workflow. For broad, free access to a wide range of SEO metrics, SEOquake remains one of the most versatile browser extensions available.
