Expired domain backlinks decay before the auction closes

Policy requires an expired .com to resolve to nothing for weeks before anyone can buy it. The links you're bidding on were counted before that, by a crawler that hasn't been back.

Link juice and link equity: what actually passes through a link

Google's documentation says PageRank is still part of its core ranking systems. The arithmetic everyone teaches for it was last restated by a Google employee in 2009, inside his own disclaimer. Both of those are on the record.

How to find backlinks in Google Analytics 4 (it only shows the clicked ones)

GA4 has no backlink report. It counts referral sessions - visits that arrived from a link somebody clicked - so a removed link and an unclicked link produce the same empty row. The current click-path, why the referring URL arrives stripped to a domain, and the six blind spots.

PBN backlinks don't fail one at a time

Google's spam documentation never uses the word. What a network link actually is in 2026, which footprints still identify one, and why four of them tend to go in the same week.

Two schema validators, two verdicts: which one decides your rich result

The same page passes schema.org's validator with three items and no warnings, and Google's Rich Results Test with two. Nothing errored. One item is simply absent. Both tools are Google's, both are right, and only one of them is telling you what Google will actually show. Run on our own page, on 14 August 2026.

A ranking dropped: what to rule out, in order

Google publishes a debugging guide for Search traffic drops. It names six causes, and backlinks aren't among them — the word doesn't appear on the page. That's not an oversight, it's a boundary: the guide covers Google's side of the glass. Here's the full elimination order, from measurement artifacts to the box almost nobody opens, with the rewrite saved for last.

Why your SERP position is three different numbers

Your browser puts you third. Your rank tracker says seven. Search Console says 11.2. Same keyword, same page, same morning — and none of the three is broken. They answer different questions, and Google documents most of the difference itself. What each number measures, two things I checked live this week that contradict the standard advice, and the one figure worth putting in a client report.

How to read Ahrefs metrics: which numbers are counted, which are guessed

DR, UR, organic traffic, traffic value, KD. They sit in identical gray boxes and look equally authoritative, but half of them are calculations over Ahrefs' own index and half are models of data only Google has. Ahrefs published the error bar on the second half itself: a median deviation of 49.52% against Search Console.
