Revenue Drops from Organic

[BeckyKey]

Hi

We've started to see steady drops in revenue since Jan 22nd each day & I can't seem to pinpoint why.

We aren't seeing a drop in traffic for those pages, but we have seen ranking drops in other areas.

The main revenue drops are coming from the homepage - it seems like a downwards trend - any ideas at how I can pinpoint the issue? https://www.key.co.uk/en/key
