Results Screen Now Leads with the 3-Layer Score
The results hero now prominently displays the 3-layer score (Ranking Signals, SERP Appearance, Technical) aligned with Google's official criteria. The overall score circle remains on the left but is now smaller and sits side-by-side with the 3 layers, so the moment you open the results you can see which area to focus on improving.
3-Layer Score Display Aligned with Google's Official Criteria
SEO scores are now broken down into 3 layers: Ranking Signals (HTTPS, mobile-friendly, page speed), SERP Appearance (title, description, OGP, rich results), and Technical (crawlability, sitemap, security). Based on ranking factors officially documented by Google Search Central, this breakdown makes it easy to see which area to prioritize. The overall 100-point score is still shown as before.
Core Web Vitals Integrated into Ranking Layer Score
Core Web Vitals (LCP, CLS, INP) — Google's officially documented ranking factors — are now reflected in your SEO score. Once the PageSpeed Insights result arrives after a check, the previously response-time-based 'Page Speed' item is automatically replaced with a Core Web Vitals-based evaluation, updating the Ranking layer score to more closely match Google's actual assessment. Available on all plans.
Spammy Structured Markup Warning Added
We now automatically detect cases where structured data declares FAQs, product prices, or review ratings that aren't actually displayed on the page, and show them as warnings. Such markup violates Google's guidelines and can lead to rich result removal or manual actions. The warnings don't affect your score — they're shown purely to alert you. Currently covers FAQPage, Product.offers.price, and AggregateRating patterns.
Structured Data Score Rebalanced Toward Rich Results
Rebalanced the structured data score to emphasize Rich Results Eligibility — the factor that actually produces visible rich results (FAQ, breadcrumbs, product info, etc.) in Google search results. Its weight increased from 8 to 20 points. Meanwhile, checks that used to reward simply placing WebSite/Organization types were reduced in weight. This improves evaluation accuracy for structured data that delivers real SEO benefit.
Improved Structured Data & Sitemap Detection Accuracy
Fixed an issue where structured data nested inside WebPage or Article (such as BreadcrumbList) was not being detected. Sitemap detection from robots.txt is now more resilient, handling multiple sitemap entries, comment lines, and BOM-prefixed files. All 21 Google-supported Rich Result types are now recognized correctly.
