Website Health Scoring & Benchmarks

When evaluating a website's SEO performance, four core metrics provide a quick diagnostic picture: overall health score, domain authority, keyword rankings, and organic traffic composition. Asymmetric uses specific internal benchmarks for each, and any site falling below them is considered a candidate for remediation.

Core Metrics & Asymmetric's Benchmarks

Overall Health Score

A site health score (as reported by tools like Ahrefs or Semrush) reflects technical SEO hygiene — crawl errors, broken links, duplicate content, plugin conflicts, and similar issues.

Asymmetric benchmark: 98 or higher
Anything below 98 is considered unacceptable and triggers a technical remediation workstream
Scores in the 70s indicate meaningful crawl and indexation problems but are not the worst case

"For us, anything below 98 is unacceptable." — Mark Hope

Example: A3 Environmental scored 77/100. Asymmetric identified duplicate plugins and structural issues as likely contributors.

Domain Authority (DA)

Domain authority (scale of 1–100) reflects the strength and quality of a site's backlink profile and overall web reputation. It is a lagging indicator — it builds slowly over years and is difficult to move quickly.

Asymmetric benchmark: 40 or higher
A DA of 20 is acceptable for a one-year-old site, but not for a company with a decade of history
Asymmetric reports no managed client sites with DA below 40

Example: A3 Environmental had a DA of 20 despite being a 10-year-old, 30-person firm. Asymmetric's own site sits at DA 55.

Keyword Rankings (Top-10 Positions)

The number of keywords for which a site ranks in Google's top 10 is a direct proxy for organic search visibility. Sudden drops in this count often signal a Google algorithm penalty, crawl errors, or content quality issues.

Watch for: Rapid declines over a short window (weeks to months)
Quality matters as much as quantity: Ranking #1 for a keyword with 30–60 monthly searches is essentially worthless for lead generation

Example: A3 Environmental dropped from 367 top-10 keywords in May to 130 — a 65% decline. Many of their remaining #1 rankings were for ultra-low-volume terms (e.g., "transaction screen assessment," 60 searches/month nationally).

Organic Traffic Volume & Composition

Raw traffic numbers matter less than the intent behind that traffic. Asymmetric segments traffic into three categories:

Intent Type	Definition	Lead Generation Value
Informational	Users seeking to learn (students, researchers)	Low
Commercial	Users comparing options before buying	High
Transactional	Users ready to purchase or contact	Highest

Target mix: ~70% commercial or transactional traffic
Red flag: 95% informational traffic means the site is functioning more like Wikipedia than a lead generation asset

Example: A3 Environmental had ~500 organic visits/month (down from ~1,000 in May), with 95% informational intent. This means nearly all of their organic visitors were unlikely to ever become leads.

AI Citations as an Emerging Metric

As AI-powered search (ChatGPT, Perplexity, Google AI Overviews) displaces traditional link-clicking behavior, a new metric is becoming relevant: AI citations — instances where an AI tool references your content in a response.

Visible in Ahrefs on the overview page
Sites with well-structured Q&A content are more likely to be cited
AI citations can drive direct referral traffic even when traditional search clicks decline

"We're seeing websites that used to get 1,000 visits a month getting 700. But of those 700, they're much better visits. And about 20% of them are coming from AI directly." — Mark Hope

This is a reason to invest in content quality during the AI transition, not to abandon SEO — the content that gets cited by AI is the same high-quality, question-answering content that ranks well in traditional search.

Diagnostic Checklist

When auditing a new site, assess:

[ ] Health score (target: 98+)
[ ] Domain authority (target: 40+)
[ ] Number of top-10 keywords — and trend direction
[ ] Volume of keywords being ranked for (are they worth ranking for?)
[ ] Traffic volume trend (growing, flat, or declining?)
[ ] Traffic intent mix (% informational vs. commercial/transactional)
[ ] Number of AI citations (emerging metric)
[ ] Conversion action density (CTAs, lead magnets, forms)
