Website Optimization

Website optimization articles on measuring the impact of every change and investigating traffic drops methodically, without relying on guesswork.

Changing the site without losing track

Every website changes all the time: a new layout, a rewritten page, a shorter form, a move to a new host. Each change can improve or hurt traffic and conversions, but the effect is rarely obvious the next day. The articles in this category show how to evaluate changes methodically.

We cover two sides of the same problem. The first is measuring the impact of a change you made on purpose. The second is investigating a traffic drop that appeared out of nowhere. In both cases, the path goes through comparing equivalent periods, isolating traffic sources and knowing exactly what changed and when.

What you'll find

  • How to decide what to watch before you publish a change.
  • How long to wait before drawing conclusions.
  • A checklist for investigating traffic drops, starting with the most common causes.
  • How to tell a technical problem apart from a normal variation for the period.

Who it's for

For people who make decisions about the website, such as business owners, marketing managers and developers, and want to know whether improvements are really working. The articles don't require A/B tests or advanced tools, although they explain when those make sense.

The piece that's usually missing

Most investigations get stuck on the same question: what changed on the site in the last few weeks? When nobody wrote it down, the answer becomes a guess. Keeping a simple record, with the date and a description of each change, solves a big part of the problem.
