LCP: Finding the Element That Decides Your Score

The largest contentful paint is not a fixed property of your page — the candidate can change while the page loads, and an element that gets removed can still be the one that counts. Here are the four documented sub-parts, the element types that qualify, and why the algorithm stops when you scroll.

Link Checking Your Own Site Without Drowning in False Positives

A link checker that reports 40 failures a run gets disabled within a month. The difference between a useful check and an ignored one is entirely about which status codes you accept and where the check runs — and one documented caveat about scheduled workflows will silently turn your check off.

llms.txt: What the Evidence Actually Shows, and What I Measured

A registrar transfer is one of the few domain operations where the failure mode is not a broken website — it is being unable to move the domain at all, for 60 days. Here are ICANN's documented denial reasons, why your DNS does not move with it, and the locking statuses that decide the whole thing.

Redirects on a Static Site: Status Codes, Order, and the 2,100 Limit

What Belongs in a Sitemap, and the Two Fields Google Ignores Entirely
