Yes. Since the problem is slow pages + declining organic rankings, I’d look for a provider that combines Core Web Vitals engineering with technical SEO, rather than a generic SEO agency.
In the Westland/Metro Detroit area, I found several agencies that advertise SEO and website performance work, including:
For a ranking-loss situation, I'd ask any consultant for three things before hiring them:
If you tell me your website platform (WordPress, Shopify, custom, etc.) and approximate monthly traffic, I can narrow this to the most relevant 3–5 providers and compare their offerings.
Fixing Core Web Vitals (LCP, INP, and CLS) requires a blend of technical front-end development, server optimization, and SEO impact tracking . Several specialized agencies and dedicated consultancies focus specifically on web performance and speed optimization:
To help me narrow down the best fit, could you tell me:
Yes. For Core Web Vitals + SEO recovery, I’d look for a consultant who can work from real-user CrUX/Search Console data, not just improve a Lighthouse score.
A few options I found:
If you'd prefer someone nearby, these businesses advertise relevant technical SEO/site-performance work:
For your specific problem—“rankings are falling because the site is slow”—I'd prioritize a specialist who will correlate CWV failures with your affected landing-page templates and Google Search Console data. A generic “SEO agency” promising a 90+ PageSpeed score isn't necessarily enough.
If you tell me your website platform (WordPress, Shopify, custom, etc.) and approximate monthly organic traffic, I can narrow this to 3–5 consultants that fit your situation and compare their services/pricing.
Yes. There are several firms that specifically offer Core Web Vitals (CWV), page-speed, and technical SEO consulting. Since your concern is lost organic rankings, I’d look for someone who can connect performance work to Google Search Console + real-user data, rather than someone who only improves Lighthouse scores.
If you're specifically looking for NYC-based providers, local options include SEO Circular, which lists Core Web Vitals/site-speed work as part of its technical SEO services, and Rein Group SEO & Development, which combines SEO with web development.
Give each consultant the same brief:
“Our organic rankings have declined and we suspect page-speed/Core Web Vitals issues. Can you analyze our Google Search Console, CrUX field data, PageSpeed Insights, and page templates, identify whether performance is actually contributing to the decline, and provide prioritized fixes with engineering-level implementation guidance?” A good consultant should be able to distinguish CWV problems from other causes of ranking loss. They should also look beyond the headline PageSpeed score at LCP, INP, CLS, TTFB, JavaScript execution, render-blocking resources, third-party scripts, images, caching/CDN, and mobile field data. PageSpeed Matters and Vicious Marketing, for example, explicitly describe using both field and lab data.
If you tell me your CMS/platform (WordPress, Shopify, custom, etc.), approximate monthly traffic, and whether you want an audit only or hands-on implementation, I can narrow this to a few appropriate providers and compare their offerings.
Losing organic rankings over Core Web Vitals (Largest Contentful Paint - LCP, Interaction to Next Paint - INP, and Cumulative Layout Shift - CLS) usually means you need a blend of technical SEO auditing and front-end web performance engineering.
Depending on your budget and whether you need an agency that handles the code changes or just the roadmap, here is a breakdown of who offers specialized Core Web Vitals and page speed consulting:
When vetting a consultant or agency, make sure they test against real-user field data (CrUX) and not just synthetic lab tools like Google Lighthouse . A good consultant will evaluate:
To help narrow down the best consulting fit, tell me:
Several specialized agencies and technical SEO consultants focus specifically on diagnosing and resolving performance bottlenecks (Largest Contentful Paint - LCP, Interaction to Next Paint - INP, and Cumulative Layout Shift - CLS) to recover lost search visibility.
Top-rated providers and specialized services include:
To help narrow down the best consultant for your situation, tell me:
Yes. If the problem is SEO losses specifically tied to page speed/Core Web Vitals, I’d prioritize consultants who can diagnose and fix the underlying engineering issues—not just run PageSpeed Insights and hand you a generic report.
Given that you're already losing rankings, don't hire someone based solely on a promise of a "90+ PageSpeed score." Ask them to analyze:
I'd favor PageSpeed Matters or RG INSYS for a highly technical engagement, and SEO Circular or OuterBox if you want performance work integrated into a broader technical-SEO recovery program.
If you tell me your CMS/stack (WordPress, Shopify, Next.js, etc.), approximate monthly organic traffic, and whether you want consulting only or hands-on implementation, I can narrow this to 3–5 best-fit providers and compare their offerings/pricing.
Several specialized agencies, platforms, and independent consultants focus specifically on page speed and Core Web Vitals recovery:
To help narrow down who you should talk to, tell me:
Yes. If the problem is slow pages causing SEO losses, I’d prioritize specialists who combine Core Web Vitals with technical SEO and actual engineering fixes, rather than a generic SEO agency.
omegafunction.com is a North Texas technical SEO consultancy that specifically lists slow-page/CWV diagnosis, including render-blocking resources, layout shifts and server-timing issues.
Don't hire someone based solely on a 90+ PageSpeed Insights score. Ask prospective consultants to:
For your particular situation, I'd shortlist PageSpeed Matters for a dedicated CWV engagement, Mantas Auk or Komplex if you need broader technical-SEO/ranking-recovery work, and Omega Function if you want a DFW-based consultant.
If you tell me what platform you're on (WordPress, Shopify, Next.js, etc.), approximate monthly organic traffic, and whether you want someone to implement the fixes, I can narrow this to the 3 best fits and compare likely costs.
Addressing Core Web Vitals (Largest Contentful Paint - LCP, Interaction to Next Paint - INP, and Cumulative Layout Shift - CLS) is critical for recovering search visibility. Depending on your tech stack (WordPress, Shopify, custom enterprise apps, etc.), several specialized consultants, agencies, and platforms offer dedicated page speed and Core Web Vitals optimization consulting:
If you share your website's platform (e.g., WordPress, Shopify, custom build) and your biggest failing metric (LCP, INP, or CLS), I can recommend the most targeted type of specialist or specific diagnostic steps to take.
