We have upgraded how it fetches results for Google AI Overviews, Google AI Mode, Microsoft Copilot and Brave AI. Scans now run on sturdier data sources with a one-time automatic retry on a backup source if the primary one fails, and Brave AI scans adapt to whatever access level is available. It's for anyone who relies on complete, trustworthy AI-search visibility data across those four engines - and there's nothing to switch on.
Missing data is a quiet problem. A scan that fails silently doesn't just leave a gap in a chart; it skews averages, makes week-on-week movement look like something it isn't, and costs you an afternoon working out whether your visibility actually dropped or the scan simply didn't complete. This update is aimed squarely at that.
What this reliability update is
This is an improvement to the data layer behind WriteWorks scans for Google AI Overviews, Google AI Mode, Microsoft Copilot and Brave AI. Instead of depending on a single path to each engine's results, scans now draw from an upgraded primary source and automatically fall back to a backup source when the primary one has an issue.
The output you see is unchanged. The same prompts, the same engines, the same dashboards - just fewer missed or partial scans feeding them.
How the improved scanning works
Scans for the Google and Microsoft engines now run against an upgraded data source. If a request to that source fails, WriteWorks automatically retries once on a backup source rather than recording the scan as incomplete.
Brave AI works slightly differently. It connects directly to Brave's own service and automatically adjusts its requests to match the access level available, then remembers which configuration worked so subsequent scans start from the right place.
A few things worth being clear about:
- The fallback is a one-time automatic retry, not an indefinite loop. Genuine, persistent outages at an engine's end still surface as errors - which is the honest outcome.
- This changes how results are fetched, not how they are scored or attributed. Your historical data and metric definitions stay as they were.
- Other engines tracked in WriteWorks, such as ChatGPT, Claude, Perplexity and Gemini, are unaffected by this particular change.
Who benefits from this
It matters most if you:
- Report on Google AI Overviews or Google AI Mode to a leadership team and need the numbers to hold up to questioning.
- Track Microsoft Copilot alongside other assistants and compare engines side by side, where one incomplete engine distorts the comparison.
- Run high prompt volumes or frequent scan schedules, where even a small failure rate compounds into visible gaps.
- Manage several brands or client workspaces and can't manually check every scan for completeness.
- Include Brave AI in your engine mix and want its coverage to behave consistently rather than depend on access conditions on the day.
Advanced users feel this most. The more prompts, markets and engines you track, the more a quiet failure rate costs you in both data quality and verification time.
What it changes in practice
The practical shift is that you spend less time asking whether a dip is real. When per-engine coverage is complete, a drop in Google AI Overviews tracking is far more likely to be a genuine change in how the engine answers - something you can act on - rather than an artefact of a failed fetch.
That has knock-on value for everything built on top of scan data. Comparisons in competitor share of voice, patterns in cited sources analysis and the ranked recommendations you work from all improve when the underlying coverage is complete across engines.
It also makes per-engine comparison more meaningful. Google's own documentation on AI features in Search is explicit that AI Overviews and AI Mode are distinct surfaces with their own behaviour, so treating them as separate lines in your reporting only works if both are being measured consistently.
How to use it
- Nothing to set up - scans for Google AI Overviews, Google AI Mode, Microsoft Copilot and Brave AI now run with improved reliability automatically.
- Open AI Search Visibility and check that all four engines are enabled for the prompt sets you care about.
- Review your scan history for those engines after the next scheduled run and confirm coverage looks complete.
- If an engine was previously patchy enough that you excluded it from reporting, add it back and compare a fresh period against the rest of your engine mix.
Tips for a better result
- Compare like with like: when you reintroduce an engine, start a fresh reporting period rather than splicing it onto older, patchier data.
- Keep scan schedules consistent across engines so per-engine movement reflects the engines, not your cadence.
- If a scan still errors, read the message - clearer error messaging tells you whether the issue is at the engine's end or with the prompt itself.
Frequently asked questions
Do I need to change any settings to get the more reliable scans?
No. The upgrade applies automatically to scans for Google AI Overviews, Google AI Mode, Microsoft Copilot and Brave AI across all workspaces. There is no toggle, no re-authentication and no change to your prompts or schedules. Your existing dashboards and reports continue to work exactly as before.
Will this change my historical visibility numbers?
No. The update changes how results are fetched, not how visibility is calculated or attributed. Existing data stays as recorded. You may see more complete coverage going forward, so compare new periods with new periods rather than assuming a change in trend reflects a change in engine behaviour.
What happens if both the primary and backup sources fail?
WriteWorks retries once on the backup source. If that also fails - for example, during a genuine outage at the engine's end - the scan is reported as an error rather than recorded as a zero or a partial result. Honest error reporting is preferable to data that quietly understates your visibility.
Why does Brave AI work differently from the other engines?
Brave AI connects directly to Brave's own service rather than through the shared data source used for the Google and Microsoft engines. WriteWorks automatically adjusts its requests to match the access level available and remembers the working configuration, so later scans start from the right settings instead of retrying from scratch.
The bottom line
Complete scan coverage is the foundation everything else in AI-search reporting sits on, and this update makes coverage for Google AI Overviews, Google AI Mode, Microsoft Copilot and Brave AI more dependable without any work on your part.
