The technical SEO newsletter engineers and SEOs actually finish
Something I hit on a live project, worked through in full, with a position on what to do about it.

Three things, every episode
Written the way I would explain it to your engineering lead, because that is usually who ends up reading it.
The long one
One specific problem, taken apart — what it actually does, why the usual reading is wrong, and where I come down on it. Argued from live projects and primary documentation, not from someone else's summary.
The TL;DR
The whole argument in four lines at the top, so you can decide in thirty seconds whether the rest is worth your time.
The roundup
The three most interesting things from the last two weeks, cherry-picked and explained — what each one means for your stack, not a list of links.
A position, not a summary.
From someone still doing the work, not summarising other people doing it.
Decide faster
Know which technical arguments are worth having with your team, and which ones do not matter at your scale.
See it early
Crawler and rendering behaviour usually changes months before anyone writes a guide about it. I hit these on live projects first.
Hand it over
Each episode is specific enough to forward to a developer without writing a covering explanation first.
I was the developer first
The long piece in every episode comes out of work I am doing. 10+ years building the web before I started fixing it for other people, and I still ship production code.
I still write production code
Not a former developer. I build and run VitalSentinel, my own technical SEO monitoring platform, so rendering, caching and edge config are current work rather than a line on a CV.
Episodes come out of client work
A small number of long engagements on enterprise sites, one of them past three million URLs. Most long pieces come straight out of what I hit there, the rest out of a vendor change nobody has read properly yet — never out of what is trending.
Every two weeks, deliberately
Long enough that each one is finished, short enough that it still matters when it lands. Twenty-six a year, and none of them written to fill a slot.

“We've been working with Martin for several years now and we truly appreciate his professional and systematic approach, which also takes our business goals into account. In addition to his deep knowledge of SEO, he's able to break down proposed strategies into actionable steps and, thanks to his previous experience as a programmer, communicate them effectively to both our editorial team and our external developers.”
