Understanding Data Differences Between Siteimprove and Google Search Console (GSC): FAQ

Environment

• Products: Google Search Console (GSC), Siteimprove
• Features: Search performance metrics, query data, page-level data
• Audience: SEO specialists, content teams, digital marketing managers, analytics stakeholders

Introduction

If you have noticed that the numbers in your Siteimprove dashboard do not seem to match the main view in Google Search Console, you have discovered a key difference in how these tools present data. This is not an error, but a fundamental distinction in purpose and perspective.

Think of it this way: Google Search Console's default dashboard is like viewing a vast forest from a mountaintop. You get a high‑level view of the entire landscape. The Siteimprove dashboard, on the other hand, is like having an expert guide on the ground with you—identifying the most important trails, trees, and scenic viewpoints. Both views are correct and valuable, but they serve different purposes: one provides a total overview, and the other delivers detailed, actionable exploration.

This document explains why these differences exist, how both platforms are “correct,” and how to use them together to gain a complete picture of your site’s performance.

A Deep Dive into Google Search Console

Navigating the Performance Report

The Performance report is GSC’s core analytical tool. It includes four primary metrics:

• Total Clicks: How many times users clicked a link to your site from Google Search.
• Total Impressions: A link to your site appearing in a viewed search result.
• Average CTR: This is calculated by dividing the total number of clicks by the total number of impressions.
• Average Position: Your site's average ranking position in the search results for a specific query or set of queries. It is important to note this is an average; your site's position can fluctuate significantly based on many factors.

By default, the Performance report shows the last three months of data, but this can be customized.

How to Replicate Siteimprove Views in GSC

GSC’s filtering system allows you to recreate Siteimprove’s granular views. Using the + NEW filter, you can refine data by:

• Search terms
• Pages
• Countries
• Devices

The Siteimprove Dashboard

How Siteimprove Gets Its Data

Siteimprove uses the official Google Search Console API. The performance data is identical to what you see in GSC—it is not estimated or third‑party data.

Why the Numbers Don’t Always Match

To build full confidence in the data from both platforms, it is crucial to understand a few technical nuances of how Google processes and presents its search data. These are not errors or bugs, but deliberate features of the GSC ecosystem that affect the data shown in the GSC interface and in any tool that uses its API, including Siteimprove.

Anonymized Queries

To protect user privacy, Google hides low‑volume or sensitive queries by grouping them into “anonymized queries.” Anonymized queries are included in GSC’s top‑level chart totals but are removed from all filtered views. This is the main reason Siteimprove’s totals will be lower than the big number on the GSC dashboard.

Data Aggregation

Aggregation "by Property": This is the default view in the GSC Performance report when no page or search appearance filters are applied. It groups all data for your entire website (the "property"). In this view, if a user clicks on one link to your site from a search results page, then goes back and clicks on a second link to your site from the same search results page, GSC counts this as a single click to the property, since the final destination is the same website.

Aggregation "by Page": When you apply a filter for a specific page or a group of pages (or when Siteimprove displays a page-level report), GSC re-aggregates the data by the specific URL.

Because of this re‑aggregation, page‑filtered reports can sometimes show higher totals than the unfiltered property‑level data.

Data Limits and Sampling

• 1,000‑row UI limit: GSC displays only 1,000 rows in its interface.
• API advantage: The API can return up to 50,000 rows per day per site per search type.
• 16‑month history limit: Older data is deleted unless stored externally—such as in Siteimprove.

Why You Don’t Need the High‑Level GSC Overview

GSC’s overview is useful for confirming that search activity exists, but it is not designed for day‑to‑day SEO analysis. High‑level totals include anonymized queries, are capped by UI row limits, and only cover 16 months of data.

Siteimprove overcomes these constraints by pulling full API data, applying standardized filters, and storing historical archives.

Why Siteimprove Provides a Pre‑Filtered Overview

Delivering Complete and Consistent Data

Siteimprove retrieves 50,000 API rows per day and stores data beyond GSC’s 16‑month window. This ensures a stable, complete dataset that reflects true page‑ and query‑level performance.

Reducing Noise

Anonymized queries make up a large share of GSC’s top-level totals, but they are not actionable. Siteimprove focuses on visible, optimizable keywords and pages—just like a filtered GSC report.

Saving Time and Providing Richer Insights

Manually filtering, exporting, and stitching together GSC data is time‑consuming. Siteimprove automates this work, integrates performance with content quality and accessibility, and provides actionable insights.

Additional Questions

So, which platform's data is "correct"?

Both are correct. Google Search Console shows the raw, unfiltered total performance of your entire site. Siteimprove shows a pre-filtered, granular view of a specific part of that performance (e.g., by page, by query). The difference lies in perspective: a total overview versus a specific, detailed analysis.

Why doesn't the total number of clicks in Siteimprove match the big number at the top of my GSC dashboard?

This is almost always due to Google's "anonymized queries." The large total in GSC includes all clicks, even from rare or private search terms. Your Siteimprove dashboard, which is a filtered view, only shows data for the non-anonymized queries, as per Google's rules. This is the expected behavior and would look the same if you applied the same filter inside GSC itself.

Can I see the exact same view in GSC that I see in Siteimprove?

Yes. Your Siteimprove dashboard is essentially an automated, pre-built version of a filtered report. You can replicate any view by applying the corresponding filters for Pages, Queries, Countries, and Devices inside the GSC Performance report.

What is an "anonymized query" and why should I care?

An anonymized query is a search term used by only a few people that Google hides from reports to protect user privacy. This matters because, collectively, these hidden queries can account for a very large percentage of your total traffic, nearly half, on average. It means that an effective SEO strategy should focus on page-level performance and broader topics, not just on the specific keywords you can see.

How up-to-date is the data in both platforms?

Both platforms pull from the same Google data source, which typically has a delay of two to three days before data is considered "finalized". While "fresh" data may be available sooner, it is preliminary and subject to change. Neither platform provides true real-time organic search data, as Google needs time to process and verify it.
