Google’s Secret Weapon Against Your Website: How the HCU Really Works

It’s been a while since Google launched its Core Update in August 2024. Tom Capper’s latest post on Moz dives deep into the Helpful Content Update (HCU). Let’s unpack it a bit, shall we?

You know how Googlers keep hinting that their search engine is simpler than we think? Well, Tom’s data seems to back that up. After poring over the last three HCUs and post-HCU-merged Core updates (Sept ’23, March ’24, and Aug ’24), he spotted a pattern in the sites that took a hit. But before we get into that, let’s set the scene a bit.

The Brand Authority Hypothesis (or as I like to call it, the “BA Theory”)

The Moz community has accomplished a real feat here. They analyzed – just imagine – about 1.9 million US-English keywords across 14,252 subdomains. That’s no small feat! And what they found was quite striking: sites that lost rankings consistently had lower Brand Authority (BA) and a higher domain authority to Brand Authority (DA:BA) ratio than the winners and those who stayed put.

This upends everything we thought we knew about HCUs. We all assumed they were related to content quality, right? But this suggests that Google may be dusting off an older, simpler system tied to navigation or branded search queries. In other words, it all depends on how much direct demand there is for a brand compared to its perceived authority.

Summary of HCU Impact Data from the Research:

1. Winner and Neutral Site Profiles:
   • HCU winners showed similar Domain Authority (DA) and Brand Authority (BA) profiles to sites that saw no impact.
   • This similarity suggests two possibilities: a) Winners were rewarded for factors not captured by DA or BA metrics. b) Search rankings operate as a zero-sum game, where losers’ drops create opportunities for others to rise.
2. Loser Site Profiles:
   • HCU losers exhibited distinctly different metrics:
     • Lower Brand Authority: Average BA of 37 compared to 50-52 for winners/neutral sites.
     • Higher DA:BA ratio: 2:1 for losers versus 1.4:1 for winners/neutral sites.
3. Comparative Analysis:
   • For any given Domain Authority, HCU losers tend to have lower Brand Authority compared to other groups.
   • Conversely, for any given Brand Authority, losers tend to have higher Domain Authority.
4. Interpretation:
   • The similarity between winner and neutral site profiles, contrasted with the distinct loser profile, suggests that the HCU likely functions as a demotion or algorithmic penalty rather than a positive ranking factor.

This data underscores the importance of balancing Domain Authority with Brand Authority in SEO strategies, highlighting a potential vulnerability for sites with high DA but comparatively low BA in the context of Helpful Content Updates.

So, what does this mean for our SEO game plan?

1. Content quality isn’t dead: Sure, HCUs might not be directly targeting how helpful content is, but let’s not kid ourselves – top-notch content is still crucial for SEO success and building your brand.
2. Brand building = SEO: The strong link between brand metrics and HCU performance means we need to start thinking of brand development as part of our SEO toolkit.
3. It’s all about balance (or as I like to call it, the “Chinese Dao” of SEO): We need to juggle traditional authority signals (links, content) with brand development. Having a sky-high DA without a decent BA might actually hurt you.
4. Expect the unexpected: The partial reversal we saw in Sept ’24 shows just how unpredictable Google’s algorithms can be. It’s a reminder that we need to think long-term with our SEO strategies.

So, where do we go from here?

As SEO pros, we’ve got to roll with the punches. Sure, we’ll keep optimizing content and building those juicy backlinks, but we should also:

• Push for more brand awareness campaigns
• Help our clients craft unique, memorable value props
• Get people to search directly for our clients’ sites
• Keep an eye on Brand Authority metrics alongside our usual SEO KPIs

By taking this holistic approach – bridging the gap between SEO and branding – we can help our clients weather these algorithm storms and see some real, lasting organic growth.

Remember, folks: SEO isn’t just about being the most relevant result anymore. It’s about being the brand that users actually want to see. So let’s get out there and make some noise!
