title: "Compare Engines"
description: "Compare your site's performance across Google and Bing side by side."
---
The `compare_engines` and `opportunity_matrix` tools let you see how your site performs across **Google, Bing, and GA4** side by side.
## What It Does
It pulls data from both Google Search Console and Bing Webmaster Tools, normalizes it, and shows you the differences. For each keyword or page, you'll see:
- **Clicks, impressions, CTR, and position** on each engine
- **Deltas** — how much the position and CTR differ between engines
- **Signals** — automatic alerts that highlight opportunities and risks
---
## Signals
The tool automatically flags important patterns:
| Signal | What It Means |
|--------|---------------|
| `bing_opportunity` | You rank well on Google (top 5) but poorly on Bing (10+). Easy win to optimize for Bing. |
| `google_dependency_risk` | Over 85% of your clicks come from Google. You're too dependent on one engine. |
| `ctr_mismatch` | Similar rankings on both engines, but very different click-through rates. Your titles or snippets may display differently. |
| `ranking_divergence` | A 7+ position gap between Google and Bing for the same keyword. Worth investigating. |

## Example Prompts
Try these with your AI agent:
> "Compare my top keywords on Google vs. Bing for the last 30 days. Which keywords rank better on Bing?"
> "Show me keywords where I'm in the top 5 on Google but not ranking well on Bing. These are my Bing opportunities."
> "Am I too dependent on Google? Check my click share across both engines."
