Every visit is counted, at any size. Cloudflare samples adaptively: below a certain volume it does not sample at all, and above it the figures are scaled up from a sample. That is a sensible engineering trade and it is fine for spotting a trend. But if you are counting conversions or checking whether a campaign paid for itself, you want the count rather than an estimate of it. Skomi does not sample at any volume.
History you can go back through. Skomi keeps months or years depending on the plan, so a year-on-year question has something to answer it.
It is the whole product, not a feature of one. Goals, funnels, revenue, journeys, apps, heatmaps, recordings and feedback. Cloudflare's is deliberately a dashboard of the basics.
