Rank Checker is a tool that helps you track your keyword rankings in search results, measure how often your brand appears (Brand Mention), and analyze Google’s AI Overview content. Everything is organized into Projects: each project is tied to one of your primary domains along with the list of keywords you want to track.
What can Rank Checker do for you?
- Track keyword rankings: see where your website ranks on Google over time, including best position, first position, and gains or losses.
- Analyze AI Overview (AIO): with the 3in1 plan, see whether your website is cited by Google AI Overview, along with the content and reference sources.
- Track Brand Mention: count how many times your brand is mentioned in search results or within AI Overview content.
- Compare competitors: add up to 10 competitor domains to compare rankings directly on the chart and data table.
- Automation and reporting: schedule automatic checks by date and time, export CSV reports, add tags, and share projects.
Two ways to run: Extension and Cloud
Each project runs in one of two ways. You choose whichever fits your needs and budget.
| Method | Description | Characteristics |
|---|---|---|
| Extension (Chrome add-on) |
Runs through the Chrome add-on installed on your machine, checking directly from your browser. | Fixed to Google Vietnam, Vietnamese, and Desktop devices. Free of charge. Requires the add-on to be installed. |
| Cloud | Runs on the server system, with nothing to install. | Flexible options for search engine, language, location, and device. Charged per check (deducted from your balance). |
Quick-start tip
- Download the Chrome add-on (if you use the Extension method) from the Chrome Web Store.
- Create a new project and enter the domain and keyword list.
- Open the project details to view rankings, charts, and reports.
Key concepts
Project
The unit of work organization in Rank Checker. A project consists of one primary domain, a list of SEO keywords, brand keywords, and a list of competitors.
Organic and AI Overview
Organic refers to traditional natural search results. AI Overview is the AI-generated summary Google places at the top of the results page. Appearing in AI Overview helps your brand get mentioned even when users do not click a link.
A note on costs
Only projects that run via the Cloud method incur charges (deducted from your USD balance). Projects that run with the Extension are free of charge because the scanning happens right in your browser.
API #2 & #3: Get Locations / Languages POST
Locations endpoint: /api/v1/open-api/locations
Used to look up location codes. Supports the name, page, and size parameters in the body.
Languages endpoint: /api/v1/open-api/languages
Retrieves the list of ISO 639-1 language codes (send an empty body).
API #4: Get Task Result POST
Endpoint: /api/v1/open-api/task-result
Retrieves the SERP ranking result of a task. Send in the taskId.
{ "taskId": 4 }The response returns the list of organic results (serpItems) and Google AI Overview information (aiOverview).
API #5: Ping Back (Webhook)
Instead of continuously calling Get Task Result yourself, you can register a Callback URL with the support team.
As soon as the system finishes the check, SerpUpdate will proactively fire an HTTP POST with the Payload (including taskId, serpItems, and aiOverview) directly to your server.
Note: Make sure your endpoint returns HTTP 200 so the system records success; otherwise the system will retry.
