Start With the Decision, Not the Number
A dashboard full of green arrows feels like good news, but pageviews and sessions on their own don't tell you whether a business is actually getting healthier. Before drawing any conclusion, it helps to ask a simpler question first: what decision would this number change? If the answer is none, it's probably a vanity metric — worth glancing at, not worth optimizing for.
Not All Traffic Is the Same Traffic
Traffic also isn't one thing. A hundred visitors from a branded search, a cold social ad, and an old blog post ranking for an unrelated term will behave completely differently once they land, because they arrived with different intent. Segmenting by source and landing page before looking at conversion rate usually explains swings that look mysterious when everything is lumped together.
Trends Over Spikes
Single-day spikes are the easiest way to fool yourself. A post going briefly viral or a single large campaign push can make a week look like a trend when it's really an outlier. Looking at week-over-week or month-over-month movement, and asking whether a change persists after the initial push fades, is a more honest way to tell whether something actually worked.
