Analytics: PostHog, Plausible, DataFast

Connect PostHog, Plausible or DataFast with an API key so Prefera can show which fixes brought visits, signups and revenue.

View as Markdown

Prefera reads your own analytics to show which fixes brought visits, signups and revenue. This happens under Integrations > Traffic and revenue. It costs you nothing extra.

Google Analytics connects separately, in the Data sources group. See Google Search Console and GA4. When Google Analytics is connected, it is used first.

What each one gives you#

ToolWhat Prefera reads
DataFastVisits and revenue per page. Per-page source (Google, AI assistants) is not available from DataFast, so those show for the whole site.
PlausibleVisits by page and source, plus conversions and revenue for goals that have revenue turned on. Needs a Stats API key, which is a Plausible Business plan feature.
PostHogVisits by page and source from your page views, including visits from AI assistants. PostHog has no revenue or conversions that fit here, so those stay empty.

Prefera reads visits by page and day, conversions and revenue. It never changes anything in your analytics, and reads at most twice a day.

Connect#

Owners and editors can connect. On the tile click Connect, follow the steps, then click Test connection and Save and connect. The key is stored encrypted and never shown again.

DataFast#

  1. Open DataFast, pick the website, then Website settings > API.
  2. Create a website API key and copy it. It starts with df_. Prefera only reads.
  3. Paste it as Website API key and save. The key is tied to one website, so there is nothing else to pick.

Plausible#

  1. Open Plausible settings, then API Keys. In the top right, make sure the team that owns your site is selected.
  2. Click New API Key, choose Stats API, create it and copy it. It is shown once. It needs a Plausible Business plan.
  3. Paste it as Stats API key and click Find my sites, then pick your Site.

You can also type the site yourself under Or type the site yourself, for example example.com.

PostHog#

  1. Open your PostHog personal API keys page. EU cloud users use eu.posthog.com.
  2. Create a key, tick Query: read and Project: read, set it to your projects, and copy it. It starts with phx_.
  3. Paste it as Personal API key and click Find my projects, then pick one. Prefera finds the region for you.

Other choices in the dialog:

  • Enter the project ID instead lets you choose the Region (US cloud, EU cloud or Self-hosted) and type the Project ID, a number found in Project settings.
  • Self-hosted PostHog takes Your PostHog address. It must be https, for example https://posthog.example.com. Leave it empty for PostHog cloud.

If it stops working#

A failing key shows Needs attention on the tile. Click Manage, paste a new key and save.

Disconnect#

Click Disconnect on the tile. The stored key and the traffic Prefera kept from it are deleted. Your analytics is not touched.

See Results and analytics for where the traffic and revenue show up.
