With So Many Metrics, What Really Matters for SEO Success?

By Cassandra Gucwa, CEO, Menerva Digital

Search engine optimization (SEO) has come a long way over the past decade. What used to be a niche field focused on keywords and backlinks has evolved into a complex discipline filled with hundreds of potential data points and metrics.

With so many options to choose from, determining what really impacts search visibility and rankings can be an overwhelming task. However, while no single metric tells the whole story, a few key factors tend to serve as reliable indicators of SEO health and performance. Focusing measurement efforts on these core areas can help streamline analysis while still providing actionable insights.

Keyword Rankings

At its foundation, SEO is about ranking highly in search engines for relevant keyword phrases. Monitoring core keyword rankings on a consistent basis provides a straightforward view into how site content stacks up against the competition for critical terms.

Sudden ranking declines warrant further diagnosis, while improving positions indicate effective optimization efforts. Just be wary of reading too much into granular ranking fluctuations, which happen routinely. Steady progress for primary keywords over longer periods is the real marker for success.

Keyword rankings are certainly an important metric, but they don’t tell the whole story. We tell our clients not to get lost in the hundreds of potential SEO metrics out there. Focus on the metrics that directly relate to your business goals – whether that’s more traffic, leads or sales. If keyword rankings are improving but conversions aren’t budging, rankings alone don’t cut it.

Organic Traffic

Rankings represent potential, but organic traffic metrics show what people are actually clicking on and engaging with. Monitoring monthly users, sessions, pageviews and other key behavior metrics tells you how well your content and pages connect with searchers once they arrive.

Ideally, improving keyword rankings should translate into a corresponding boost in qualified visitors finding your site from search engines. If not, site or content issues may be undermining real-world user experience and engagement.

Click-Through Rate

Click-through rate (CTR) is another useful proxy for gauging real search engine user behavior. A ranking page may receive millions of impressions, but a low CTR signals problems capturing attention and interest.

By tracking CTR for individual pages and positions over time, you can diagnose issues with elements like titles, metadata, and page content quality that may be limiting performance despite strong rankings alone. High and rising CTR points to compelling and relevant page experiences for searchers.


Before any content has a chance to rank, search engines have to properly crawl, process and add pages to their massive indexes. Tracking indexation metrics helps ensure that sites have the technical SEO fundamentals covered.

Major red flags like large numbers of pages blocked from indexing or pages dropping out of indexes unexpectedly can significantly undermine performance. Indexation rates also offer insight into how effectively sites and pages are architected to be search engine friendly.

Links and Referring Domains

Inbound links remain an ingredient in search ranking algorithms, especially from quality sites relevant to a page’s content. Monitoring total links and especially unique external sites (referring domains) pointing to your pages over time gives a rough gauge of how well your content attracts citations organically.

Sudden drops in links or domains may reveal technical issues or devaluing link practices deserving more scrutiny. Be careful, though – links can ebb and flow significantly, so don’t overreact to typical fluctuations. Steady or accelerating growth in quality links signals strengthening authority.

Local SEO Signals

If your business serves local customers or has brick-and-mortar locations to drive foot traffic towards, monitoring standard organic search metrics often isn’t enough. Key local SEO signals like Google My Business data, reviews and citations take on amplified importance.

Regularly check dashboard metrics within Google My Business to spot issues like inaccurate business info or suspended accounts that undermine visibility across Google’s local pack and maps. Maintain a steady accumulation of positive local reviews, while monitoring metrics like average rating that can influence local pack ranking. And consistently verify or update directory citations and NAP (name, address, phone) information to strengthen local SEO authority signals.

Conversions and Value Per Visit

While higher organic traffic is clearly positive, more qualified visitors won’t matter much if they aren’t converting into customers or leading to meaningful engagement. Analyze conversion rates from organic traffic sources, digging into exactly how visitors land and what actions they ultimately complete (or don’t) on your site.

Look at value per visit as well, whether through average time on page, pages per session or goal completions. If measures like bounce rates are high or page depth is minimal, SEO visibility isn’t necessarily translating into valuable customer experiences. Direct user testing or surveys can also shed light on exactly where and why the search journey is breaking down.

Putting It All Together

While no metric gives a perfect or complete picture, tracking rankings, traffic, engagement, indexation and links over longer periods for priority keywords and pages offers a robust framework for monitoring SEO success. As algorithms and data evolve rapidly, stay focused more on trends than absolute numbers. Progress across these core areas points to improving organic search visibility that pays dividends in qualified website visitors.

SEO success is about striking a balance between monitoring the numbers and understanding the human behavior behind them. Don’t just look at last month’s traffic or rankings. Talk to real customers about their search experience and let those insights guide your optimization strategy.
