I'm building a web analysis platform focused on technical SEO, and I'd love to hear what other SEO professionals actually use in their daily workflow.

I'm not looking for a list of "nice-to-have" features. I'm more interested in the things that make you keep coming back to a tool instead of opening three different ones.

Some examples:

• Crawl analysis
• Core Web Vitals
• JavaScript rendering issues
• Internal linking analysis
• Structured data validation
• Indexability checks
• Log file analysis
• Internal PageRank / link equity visualization
• Duplicate content detection
• AI-powered recommendations

But I'm sure there are things I'm missing.

If you could design the perfect technical SEO tool today, what features would be non-negotiable?

Also curious about:

• what do existing tools (Screaming Frog, Ahrefs, Semrush, Sitebulb, JetOctopus, etc.) still do poorly?
• what wastes the most time during technical audits?
• is there anything AI could genuinely improve instead of just generating generic advice?

I'm looking for honest opinions from people doing technical SEO regularly.

A correlational study of 6,824 pages across 57 signals, built on real Italian SERPs. Here's what actually associates with ranking position on google.it, and what doesn't.

Methodology

The dataset was built from opportunity keywords pulled via Google Search Console across five real sites in different niches: herbalism, 3D printing, cybersecurity, pet e-commerce, and web agency. After expanding with Autocomplete variants, the final set reached 841 verified Italian keywords.

For each keyword, the top 10 organic results were scraped from google.it (it-IT locale, Playwright/Chromium, 8-15s random delay), producing 7,404 URLs, of which 6,824 were unique and crawlable.

Each URL was processed with a custom crawler: real browser load, Lighthouse for Core Web Vitals, extraction of 57 technical and on-page signals. Spearman correlation was then computed against SERP position (1-10), with a significance threshold of p < 0.05.

Statistically Significant Factors

Out of 57 factors tested, 10 reached statistical significance. Sorted by |r|:

Factor	r	p
Keyword in title	-0.087	<0.001
Keyword in URL	-0.071	<0.001
Keyword in H1	-0.056	<0.001
Keyword in meta description	-0.055	<0.001
Number of H2 tags	-0.039	<0.001
External links	-0.039	0.003
Keyword in H2	-0.036	0.002
Number of H1 tags	-0.033	0.004
.it TLD	-0.031	0.007
Text/HTML ratio	+0.045	<0.001

Negative r = correlated with better positions. Text/HTML ratio is the only factor where a higher value correlates with worse rankings.

What Didn't Show Up

Factor	r	p
LCP	-0.011	0.358
FCP	-0.007	0.574
CLS	-0.002	0.840
Lighthouse performance score	+0.009	0.445
Word count	-0.007	0.603
Schema markup	-0.019	0.100
HTTPS	+0.010	0.368
Title tag length	+0.002	0.897
URL depth	+0.003	0.772

Core Web Vitals are consistently non-significant. The most plausible explanation: within the top 10 for competitive Italian queries, sites are already fast enough that performance stops being a differentiator. The variance isn't large enough to produce a signal.

Notable Findings

Keyword placement in on-page elements

The keyword-in-title effect is real and consistent. Pages in positions 1-3 had the target keyword in the title 11.4% of the time; positions 7-10 had it 5.7% of the time. The same pattern holds across URL, H1, meta description, and H2. This isn't stuffing; it's basic topical signal.

Text/HTML ratio

Pages with a high ratio (lots of visible text, minimal HTML structure) tend to rank worse. This is separate from word count, which showed no significant correlation. The likely explanation is structural: a well-organized page with navigation, sidebars, and components has proportionally less text relative to total HTML than a bare wall of text with minimal markup.

The .it TLD

In an earlier version of the study (n=601) this factor appeared non-significant with a positive correlation. At 6,824 pages it flips to r=-0.031, p=0.007. 65% of positions 1-3 are on .it domains versus 61% at positions 7-10. Small effect, but it holds up, and it makes sense for a locale-specific SERP.

H2 count vs. word count

More H2 tags correlates with better positions. Word count doesn't. Structure matters; length doesn't.

Caveats

This is a correlational study across five specific niches. Correlation is not causation. Off-page signals (backlinks, domain authority) are not in the dataset. Results may differ for e-commerce or transactional queries.

Manetti, G. (2026). Google Italy Ranking Factors 2026: A Correlational Analysis of 6,824 SERP Pages Across 57 Technical and On-Page Signals (3.0). PerseoDesign. https://doi.org/10.5281/zenodo.20797976

I was curious whether Italian SERPs follow the same "rules" as english ones, so I pulled 135 keywords from my own sites' Search Console (positions 4-20), scraped the top 10 results from google.it using Playwright, and ran Spearman correlation on 10 on-page factors across 601 pages.

Only three factors came out statistically significant:

- Keyword in H1 (r = -0.144, p = 0.0004)
- Keyword in title tag (r = -0.139, p = 0.0006)
- Keyword in URL slug (r = -0.112, p = 0.006)

What surprised me most: word count had r = -0.011, p = 0.79. Basically noise. Pages ranking 1-3 averaged 1,949 words vs 3,383 for positions 4-6.

The catch is obvious in hindsight: Wikipedia shows up in top 10 for 65% of my keywords, Treccani for 57%. They don't need long content, because domain authority just wins.

Also non-significant: HTTPS (99.2% adoption, no differentiation), Gulpease readability score, content freshness, .it TLD.

Worth noting this is a pilot study, limited dataset, specific niches, and unmeasured factors like backlinks and behavioral signals. I'm expanding to 1,000+ keywords using Google Autocomplete to diversify niches. Will share the follow-up here when it's ready.

Has anyone seen similar patterns in non-English SERPs? I'm wondering if the word count thing is an Italy-specific authority problem or more general.
