Comparison limits and historical data ranges
SEO Gets comparison features let you stack your current performance against a previous period, but the range you can compare depends on what Google Search Console has retained and whether your site uses extended storage.
Comparison modes available
The Comparison Period section in the date picker offers five modes:
Disabled — No comparison; only the selected date range is shown.
Previous Period — Compare against the immediately preceding period of the same length.
Previous Month — Compare against the prior calendar month.
Year Over Year — Compare against the same calendar period from the previous year.
Custom — Choose any two date ranges to compare. If the ranges overlap or differ in length, the dashboard shows a warning.
How far back you can compare
Google Search Console retains data for up to 16 months. In SEO Gets, the dashboard respects this cap, so the oldest GSC data you can select is roughly 497 days back from today.
Without extended storage, true year-over-year comparisons are only possible while your data is still within that 16-month window. Once older data rolls off, the corresponding comparison period disappears.
When a Super Site unlocks older data
A Super Site stores up to 5 years of historical data. If you enable it now, future comparisons will have access to a much longer window. Super Sites cannot recover data that was already purged from GSC before you turned on extended storage.
Super Sites store up to 5 years of historical data, giving you a much longer window for year-over-year and multi-year trend analysis.
