Is Semrush Still Relevant? Google's August HCU Update Changed Everything

The Google HCU Update's Impact: Bloggers Question Semrush's Accuracy

If you’re a blogger or SEO expert who has noticed some wild shifts in SEMrush’s numbers recently, you’re not alone. Ever since Google’s big August HCU Update, there’s been serious buzz in the SEO world that Semrush’s stats aren’t syncing with reality. Multiple bloggers report that their SEMrush numbers show shocking traffic drops—sometimes up to 60% below their real traffic. And it’s not just Semrush’s traffic numbers; it’s also keywords, rankings, and impressions that are seemingly out of whack.

The August HCU has been devastating for countless bloggers, fueling a heated debate over Google’s credibility. With unexpected traffic drops, many are questioning if Google’s constant algorithm tweaks are truly improving content assessment or just making it more unpredictable. Between the big changes in March and August, the whole SEO landscape feels shaken up. Are tools like Semrush simply outdated now? Here’s what’s going on.

The Semrush Issue: Bloggers Speak Out

The disconnect between Semrush's metrics and actual data is the biggest red flag for bloggers. Instead of providing helpful insights into keyword rankings, traffic patterns, and growth opportunities, SEMrush’s data has drifted significantly from reality. Many bloggers say they’re seeing consistent increases in keyword rankings and “Google exposure” in SEMrush, but in real life, traffic numbers tell a very different story.

Here’s what some bloggers had to say:

“I’ve been relying on SEMrush for years, but it’s giving me no choice but to look elsewhere. My real traffic is up, yet SEMrush is telling me I’m 50% down. I don’t know what happened after the August update, but it’s become pretty much useless.”
— Mark Thompson, San Diego, Tech Blog

“I thought SEMrush was glitching when I saw the 40% difference between their traffic estimate and my actual data. Turns out, that’s just the ‘new normal’ since Google’s HCU update. It’s frustrating.”
— Sarah Lee, Austin, Lifestyle Blog

“It’s strange to see all my keywords apparently ‘gaining traction’ on SEMrush while my Google Analytics tells me traffic has stalled. Feels like the whole platform is living in another reality post-HCU.”
— Alex Chu, New York, Travel Blog

These gaps in SEMrush data are prompting many users to question the platform’s reliability. SEMrush used to be one of the go-to tools for tracking SEO growth, discovering new keywords, and assessing site performance. But with discrepancies of up to 60% and keyword trends not matching Google Search Console data, SEMrush’s value is being called into question.

Why Google's HCU Changed the SEO Game

Google rolled out two major HCUs this year—one in March and another in August—that are impacting the entire SEO landscape. These updates represent Google’s attempt to prioritize genuinely helpful, high-quality content over articles loaded with keywords but lacking real value. Google has signaled a shift away from low-quality, SEO-optimized content toward articles that meet user needs authentically and directly.

The March HCU started the trend, but the August update seemed to add even more weight to content relevance, search intent, and user satisfaction. Sites that rely heavily on SEO strategies alone, without a strong focus on quality content, were hit the hardest. This shift left some of the most popular SEO tools struggling to keep up, as the updates made the usual metrics and ranking predictors far less reliable.

The massive volatility following these updates means Google’s ranking metrics are in constant flux, which might explain why tools like SEMrush are experiencing difficulty in providing accurate metrics.

What Exactly is SEMrush?

For those unfamiliar, SEMrush is one of the leading SEO tools used by marketers, bloggers, and businesses alike. Known for its detailed analytics and data-driven insights, SEMrush provides reports on keyword rankings, competitor performance, organic traffic, and backlink profiles. It’s often relied on for strategic decision-making in the SEO and digital marketing world.

Using complex algorithms, SEMrush tracks data like keyword positions, search volume, site traffic estimates, and SEO health scores. However, its reliance on historical data and external sources means SEMrush’s metrics are vulnerable to sudden shifts in Google’s algorithm, such as the recent HCU. When Google changes how it ranks and values content, SEMrush must quickly adapt or risk losing accuracy—a challenge it seems to be facing in 2023.

SEO Tools Losing Relevance? Here's Why

Google’s August HCU has cast doubt on the whole concept of “predictable SEO.” With such high ranking volatility, SEO tools like SEMrush, Ahrefs, and Moz are all facing major challenges. These tools are built on historical data and, generally, predict future trends based on how Google has ranked content in the past. But with Google’s constant refinement and emphasis on quality over quantity, it’s increasingly hard for tools to keep pace.

The HCU shifts also mean that what Google considers “relevant” content changes regularly. The usual indicators—keyword density, backlink profiles, and even some page performance metrics—don’t seem to hold the same weight as they did before. SEMrush’s perceived reliability, therefore, might continue to drop if Google’s ranking methods become less predictable. This may signal a need for the entire industry to adopt new metrics that better reflect Google’s current priorities.

As the future of SEO pivots towards quality-driven and intent-based content, SEO tools will have to evolve to remain useful. With the continued volatility in search results, accurate data from tools like SEMrush may not become fully reliable again until Google’s ranking criteria stabilize.

The Takeaway: Is SEMrush Still Relevant?

While SEMrush has historically been a valuable resource, the recent discrepancies in traffic estimates and keyword trends since Google’s HCU updates have made it clear that it’s no longer the straightforward tool it once was. Bloggers and digital marketers are facing an uncomfortable reality where SEMrush and similar SEO tools can no longer be trusted as their primary metrics. For now, it may be more helpful to focus on Google Search Console for organic data and rely less on third-party tools.

As Google continues to prioritize genuine, helpful content over SEO-heavy articles, SEMrush might need to rethink its data models if it wants to stay relevant. For bloggers, it’s probably time to look closely at your actual audience engagement, not just the metrics SEO tools report. Ultimately, prioritizing authentic content that resonates with readers may be the best SEO strategy moving forward.
