The metric that precedes everything else on your page — and what it actually measures.
Time to First Byte is not a page speed metric in the traditional sense. It is a server metric. It measures how long your server takes to begin responding. Every other load event — images, scripts, fonts, layout — starts its clock after TTFB ends.
You do not need specialized tools to check your TTFB. Browser developer tools, Google PageSpeed Insights, and WebPageTest all expose this metric. This piece walks through how to find it and what the numbers mean in context.
High TTFB can come from several sources: slow server hardware, database query time, application processing, DNS resolution, or network distance. Not all of them are hosting problems. This piece helps you identify which portion of your TTFB is attributable to hosting infrastructure.
Largest Contentful Paint is a Core Web Vitals metric that Google uses in ranking. It is heavily influenced by TTFB because LCP cannot begin until the server has responded. Understanding this dependency clarifies why server-level improvements often have outsized effects on CWV scores.
What content delivery networks actually do, and when they help or complicate things.
A CDN stores copies of your content at edge locations around the world. When a visitor requests your site, they get served from the nearest edge node rather than your origin server. That is the theory. The practical reality depends heavily on where your visitors are and where the edge nodes actually are.
A local plumber in St. Louis does not benefit from CDN edge nodes in Singapore. The geographic math matters. This piece explains how to think about CDN value for businesses with geographically concentrated audiences versus nationally distributed ones.
When a CDN caches your pages, it can serve stale content to Googlebot. Misconfigured cache headers can mean Google sees an outdated version of pages you have updated. This piece covers the cache-control configurations that matter for crawl accuracy.
When switching hosts helps rankings, when it hurts them, and how to tell the difference.
A host migration checklist is not just a nice-to-have. The items on it correspond directly to the most common causes of post-migration ranking drops. This piece goes through each item — what it is, why it matters, and how to verify it.
There are specific technical conditions where moving to a different host can measurably improve SEO performance. This piece describes those conditions and explains the mechanism behind the improvement — so you can evaluate whether your situation fits.
The ranking drops that follow badly executed migrations are not random. They follow predictable patterns related to redirect errors, SSL gaps, DNS timing, and server environment differences. Understanding the failure modes helps you avoid them.
Tools and methods for measuring what your hosting infrastructure actually delivers.
Several free tools provide useful data about server response time, TTFB, and geographic performance variation. This piece describes what each tool measures, what its limitations are, and how to interpret the output without over-reading the numbers.
Search Console contains data that reflects hosting performance — crawl stats, index coverage, and Core Web Vitals field data. This piece explains which reports to look at and what patterns suggest hosting-related issues versus content or configuration issues.
