Frequently Asked Questions

How do Core Web Vitals affect US Google rankings?

Core Web Vitals are a confirmed Google ranking factor in the US market. LCP under 2.5 seconds, INP under 200ms, and CLS under 0.1 are the thresholds. US sites failing these metrics lose ranking positions to competitors who pass — particularly impactful in competitive New York and LA markets where every position change has significant revenue impact.

Do you handle JavaScript SEO for React and Next.js US sites?

Yes — JavaScript rendering is a major technical SEO challenge for US SaaS and ecommerce sites built on React, Next.js, Vue or Angular. We audit Googlebot rendering using Google Search Console, identify content not being indexed, and implement server-side rendering (SSR) or pre-rendering solutions that ensure full crawlability.

How do you manage crawl budget for large US ecommerce sites?

For US enterprise ecommerce with 100K+ product pages, crawl budget management is critical. We use robots.txt, XML sitemaps, canonical tags, and internal linking architecture to ensure Googlebot discovers and indexes your most important product and category pages first, maximising ranking potential for high-value US commercial queries.

How does iOS 17 affect technical SEO tracking for US sites?

Apple's iOS 17 Privacy Manifest requirements affect click data from Safari, impacting attribution accuracy. We implement server-side GA4 enhanced conversions and Google Tag Manager server-side containers that maintain accurate US traffic attribution despite Apple privacy changes, keeping your SEO performance data reliable for New York and LA campaigns.
