Problem
Discover fell from more than 1,000 clicks a day to zero in the August 2023 core update
Work
LCP image, icon font, ad-slot layout shift, scripts and cron
Outcome
Mobile Core Web Vitals passed November 1. The first Discover clicks returned November 7

There are traffic drops you can fix with one plugin setting, and there are drops where the graph simply goes flat. This is a case study of the second kind. The first Discover clicks came back six days after mobile Core Web Vitals passed validation. Here are the dates, the drop, the diagnosis, and the work. If you need this work on your own site, the Google Discover recovery service page is the place to start.

The receipt: five dates

Traffic recoveries attract loose talk, so here are the dates:

  1. Core update. Discover falls from 1k+ clicks a day to zero.

  2. Work starts. Two months flat, and Core Web Vitals is the only thing still failing.

  3. Mobile Core Web Vitals pass.

  4. First Discover clicks return, six days later.

  5. Desktop validation passes.

The drop: from a four-figure daily stream to zero

The site had never drawn fewer than about a thousand Discover clicks a day. That is a stable, four-figure daily stream, the kind of traffic a publisher plans its schedule around. When the August 2023 core update rolled through, the graph fell to absolute zero and stayed there for two months.

What made the drop unusual was what it wasn’t. Everything else in Search Console looked clean. The publisher had already spent six months optimizing for Discover. The only thing still failing was Core Web Vitals.

That shaped the whole engagement: when everything else in Search Console is clean, the fixable part of the page experience is on your side of the table.

The diagnosis and the fix (October 19 to November 2023)

A Core Web Vitals audit on a Discover-dependent news site turns up a familiar set of suspects. Here is what the work actually consisted of:

  • LCPThe main image was lazy-loading itself out of contention. It came out of lazy-loading and was preloaded with high fetch priority, so the browser fetched it first instead of last.
  • Page weightAn icon font carried weight nobody used. The 78 KB icon webfont went down to 1 KB of glyphs actually used.
  • CLSAd slots had no reserved space. CSS min-height went onto every ad slot so banners stopped shoving the layout as they loaded.
  • Main thread and serverBackground noise. The Taboola widget was deferred, an ad-inserter JavaScript error was cleared, and WP-cron moved to a system cron so scheduled work stopped firing on visitor pageloads.

None of this is exotic. It is measurement, prioritization, and the discipline to fix the boring things in the right order.

An honest note on cause and effect

Nobody outside Google can force Discover back: not an agency, not a plugin, not a consultant with a theory. What can be said honestly is the order of events: passing Core Web Vitals validation preceded the first returning clicks, by six days here. That is one site’s order of events, not a promise from Google.

The project records show Discover starting to recover on November 7, and the publisher had noticed it too by the next day. They do not show how far the daily number climbed after that, so this post does not claim Discover got back to a thousand clicks a day.

What came after

The contract didn’t end at validation, and passing once didn’t settle it. By December 2023 some pages were failing again, and through 2024 the relationship continued, keeping CLS in check against the things that normally break it on an ad-funded site: a floating video player, a load-more button, and new ad units. DebugBear RUM went in as well, so shifts surface in real-user data before Google’s 28-day averages even register them.

The engagement ran as three contracts from October 2023 to 2025. On an ad-funded site, passing is the start, and staying green takes upkeep.

“Solved all the CWV issues I had and passed CWV.”

The publisher of gfcnieuws.com, public Upwork feedback, score 4.85.
