# Platform Comparison

> Compare AI Search visibility across ChatGPT, Perplexity, Gemini, Google AI Mode, and Microsoft Bing Copilot to find platform-specific gaps and decide where to invest content.

Different AI platforms surface your brand differently. Understanding platform-specific performance helps you decide whether you need broad content improvements or platform-specific fixes.

## Why Platforms Differ

Platforms vary because they draw on different data and present answers differently:

* **ChatGPT** mixes model knowledge with live web search
* **Perplexity** is citation-heavy and search-native
* **Gemini** and **Google AI Mode** are shaped by Google's search ecosystem
* **Microsoft Bing Copilot** combines web search with conversational answers

This affects:

* How often platforms mention brands
* How many sources they cite
* Which kinds of pages they prefer to cite

## Platform Availability by Plan

Platform coverage depends on your plan:

| Platform       | Starter | Plus | Pro | Agency / Enterprise |
| -------------- | ------- | ---- | --- | ------------------- |
| ChatGPT        | Yes     | Yes  | Yes | Yes                 |
| Perplexity     | Yes     | Yes  | Yes | Yes                 |
| Gemini         | Yes     | Yes  | Yes | Yes                 |
| Google AI Mode | No      | No   | Yes | Yes                 |
| Bing Copilot   | No      | No   | Yes | Yes                 |

## What to Compare

At the platform level, the most useful comparisons are:

* **Presence Rate**
* **Brand Mention Rate**
* **Primary Citation Share**
* **Share of Voice**

These make it easier to spot situations such as:

* Strong overall performance but weak Perplexity citations
* Good citation coverage but weak ChatGPT brand mention rates
* Competitor strength concentrated on only one platform

## How to Use Platform Comparison

### Find platform strengths

Look for platforms where you are already strong:

* High presence
* Strong citation share
* Healthy Share of Voice

These are your current benchmarks.

### Find platform weaknesses

Look for platforms where you underperform:

* Low presence compared to your other platforms
* Low or declining Share of Voice
* Weak citation coverage versus competitors

These are usually the best starting points for deeper prompt or citation analysis.

## Reading the Results

When one platform looks much weaker than the others, ask:

* Are competitors winning the same prompts there?
* Are those responses citing a different class of content?
* Are we being mentioned but not cited, or absent entirely?

Usually the next step is to jump into:

* **Prompts** for prompt-level breakdown
* **Citations** for URL-level detail
* **Competitors** for the competitive landscape
