Technical SEO, search intelligence, and the code behind it — notes from 20+ years of making websites work harder.
Panda used to land overnight; 4.2 will drip out over months. Fairer for site owners hit by false positives — and the end of the rank-tracker theatre that correlated every wobble to a named update.
Six months trying to growth-hack a B2B2C product taught me two uncomfortable things: without control of the end user, scale is a fairy tale — and growth is an attitude, not a playbook.
Soft 404s, misconfigured Expires headers, hidden redirect chains — when a large corporate site misbehaves in search, the answer is almost always in the HTTP headers. Three checkers I actually use, and one I don't.
You've got a folder full of CSVs and you need one. `ls`, piped through `xargs`, into `cat` with an append redirect — done, in a single line. The quiet joy of Unix pipelines.
Most Mac apps refuse to run twice at the same time. When you genuinely need two copies — Java apps are often the culprit — one terminal flag solves it, and a tiny AppleScript makes it permanent.

When two versions of a page tell slightly different stories, the terminal has a forty-year-old tool that still reads them faster than any GUI. A quick SEO-flavoured tour of diff.
Your site has been hacked. The instinct is to rush and open it to see what happened — which is exactly the wrong move. Three rules and a handful of tools for a calmer diagnosis.
Inspect Element shows the DOM after the browser has fixed things up — which is not the same as View Source. A small but costly distinction, told through a heated G+ diatribe.
