12. History & re-analysis
Finding past reports
Everything you analyze is saved. Use the left sidebar:
- History lists your recent analyses. Use the filter box at the top to find one by name.
- Analyzed Channels and Analyzed Playlists group your channel and playlist runs.
Your analysis history is kept for as long as your account exists — select any item to reopen its full report. The YouTube data inside a report (titles, thumbnails, view counts) is refreshed or cleared on YouTube's 30-day cycle, but your analysis stays.
When to re-analyze
Open a report and choose Re-analyze (also available on each video card in a collection). Re-analysis makes sense when:
- You want to add premium insights you didn't include the first time (for example, add SEO or Audio Health).
- The video has changed — a new title, thumbnail, or a re-upload — and you want a fresh read.
- An earlier run had stale or incomplete data and you want to re-scan from scratch.
On the Configure screen you'll see a Re-scan from scratch option. Turning it on reads the video again instead of reusing saved results — slower and it uses more credits, but it fixes stale or wrong data from an earlier scan.
What re-analysis costs
Two different things happen under Re-analyze. Adding modules to an existing run (for example adding SEO or Audio Health) reuses what was already read and bills only the modules you add. Re-scan from scratch reads the whole video again and costs the same as a fresh analysis. The Configure screen always shows the estimate first. Details and the uploaded-video case are in Chapter 13.
Re-analyzing an uploaded video
For uploads, the file is kept on Google only briefly (see Chapter 3). If the temporary copy has expired when you try to re-scan or run a new lens, the app will ask you to Upload again — that re-processes the file, after which the deeper tools work as normal.
