SERP Sonar

About

>> IMPORTANT NOTICE:
On September 14, 2025 Google removed support for the num=100 parameter. This variable has, for over 20 years, allowed users and SEO tools to display up to search 100 results in a single SERP page. Google made this change (as they often do) with no advance notice. 

This change affects many SEO and marketing tools, including SERP Sonar. The num=100 parameter is how SERP Sonar could extract up to 100 results in a single request. For now, this is no longer possible.

All other features of SERP Sonar continue to function normally but analysis can only be done on the first ~10 results in the SERP. This change has had an industry-wide impact and we (like other tool providers) are exploring technical options to work around the issue. 

Until then, we appreciate your patience and understanding, and thank you for not giving us a 1-star review (as the cause here is beyond our control). We DO share your frustration and if we could give Google a 1-star rating we would. :)

You can always contact us through support here or via the SERP Sonar website. We will update as soon as we have a workaround. Thanks and good luck in the SERPs. 

==============================

Overview
SERP Sonar is a free digital marketing and SEO extension for Google Chrome and Chromium-based browsers. It helps you perform deep analysis on the Google search engine results page (SERP), by extracting data and generating information-rich reports. 

This tool delivers actionable data and insights to drive higher organic rankings and more targeted paid traffic. SERP Sonar uncovers data and insights from beneath the surface of the search engine results page.

The analytics and reporting features of SERP Sonar allow you to query a keyword and see multiple dimensions of current-day data, pulled directly from the location-specific Google results page. In just seconds SERP Sonar scans the first ~100 ranking results pages, along with SERP features and attributes. After retrieving the raw data, the tool applies averages, derived metrics and rule sets to provide quick insights and an in-depth report with actionable takeaways.

These reports lets you dive deep into keyword and competition analysis. SERP Sonar then helps you fine-tune your pages to better compete and increase rankings for a given keyword. It can inform better paid marketing and brand campaign decisions as well. 

The SERP Sonar plugin is also now integrated with the OpenAI API. This delivers AI-powered Keyword Intent analyses and SERP-specific suggestions for optimized title tags and meta descriptions. By feeding OpenAI key details from the ranking pages and SERP (and not just the keyword) SERP Sonar can deliver super-charged results.

The wealth of data from both the organic results and the SERP page itself helps measure keyword supply and demand, optimize title tags and descriptions, confirm keyword intent, quantify brand or topic prominence, and much more.

SERP Sonar Benefits Include:
- Optimize and supercharge title tags for maximum ranking and CTR
- AI-based search term intent analysis with OpenAI API integration
- Measure keyword supply and demand and KGR with True Allintitle
- See competitor ad and affiliate networks highlighted right in the SERP
- Refine descriptions, headers and articles with semantically related words
- Identify use and type of schema on competitor pages without leaving the SERP
- Measure and analyze keyword concentration throughout competitor content
- Assess SERP congestion as part of overall keyword opportunity
- Generate detailed keyword and SERP analysis reports for clients

And the product roadmap is long so there is much more to come. A number of data studies are in progress and the reports will continue to be refined.
