Google's March 2025 core update rolled out over 14 days and shook rankings across industries. We tracked 47 client sites through the volatility. Here's what we found, what worked, and the four-step recovery framework we used.

What actually changed

After analysing ranking data across our portfolio, three patterns emerged:

1. E-E-A-T got real teeth. Sites with demonstrable first-hand experience — actual product reviews, original photography, named authors with verifiable credentials — held rankings. Generic affiliate-style content dropped 20-40%.

2. User engagement signals matter more. Time on page, scroll depth, and repeat visits correlated strongly with recovery. Sites that bounced users quickly were penalised harder than in previous updates.

3. Helpful content filter expanded. The HCU is now classifying sites wholesale, not page-by-page. One section of low-value content can drag down your entire domain.

The four-step recovery framework

For the 23 sites that saw declines, we ran the same playbook:

1. Audit with brutal honesty

We asked every client: "Is every page on your site something you'd proudly send to a friend?" If not, it got cut, consolidated, or rewritten.

2. Inject first-hand experience

Stock photos became real photos. Generic guides became specific case studies. Borrowed research became original data. This alone recovered 40% of traffic within 6 weeks.

3. Tighten internal linking

We rebuilt site architecture so authority flowed to pages that actually converted — not pages that just happened to have lots of links.

4. Improve engagement metrics

Better intros, scannable subheadings, embedded videos, comparison tables. We A/B tested layouts and tracked scroll depth.

What we got wrong

Two clients didn't recover despite running the full playbook. Both had one issue in common: thin category pages with filtered product listings that Google saw as doorway pages. We redesigned these as topical hubs with editorial content.

The takeaway

Core updates aren't random. They reward sites that genuinely help users and punish sites that play algorithm games. The agencies promising "quick recovery hacks" are usually selling the same tactics that caused the drop.

The boring truth: better content, better UX, better signals. Every time.
