Website-health guides for SEOs
Hands-on guides for the technical issues that quietly cost sites traffic — broken links, the wrong kind of redirect, an SSL certificate that lapsed overnight, 404s that should have been fixed. Plain-English, with the tools to check your own site as you go.
How to find and fix broken links
A practical walkthrough for finding broken links on your site, working out why each one breaks, and fixing them so visitors and crawlers stop hitting dead ends.
301 vs 302 redirects: which to use and why
The difference between 301 and 302 redirects, when to use each, how they affect SEO and link equity, and how to verify a redirect is doing what you intended.
SSL certificate expiry: why it matters and how to stay ahead
Why SSL certificate and domain expiry matter, what actually breaks when they lapse, and how monitoring keeps you from finding out the hard way that one expired.
HTTP status codes explained: a practical primer for SEOs
A plain-English primer on HTTP status codes for SEOs: what the 2xx, 3xx, 4xx, and 5xx families mean, which ones affect rankings, and the codes worth knowing.
How to fix 404 errors (and when to use 410 or 301)
How to diagnose and fix 404 errors, spot soft 404s, and decide when a missing page should be redirected with a 301 or retired cleanly with a 410.
SEO site migration checklist: move without losing rankings
A step-by-step checklist for migrating a site without losing rankings: map old URLs to new, set 301 redirects, and run the post-launch checks that matter.
Redirect chains and loops: find them and flatten them
What redirect chains and loops are, why they waste crawl budget and slow your pages, and how to find every multi-hop redirect and flatten it to a single jump.
Canonical tags explained: what rel=canonical does and when to use it
What the rel=canonical tag does, the common mistakes that quietly hurt rankings, and when to use a canonical tag versus a redirect to handle duplicate content.
Website uptime monitoring: what to watch and how often
Why uptime monitoring matters, what to watch beyond a simple ping, and how to set a check and alert cadence that catches outages before your visitors do.
Core Web Vitals explained: LCP, CLS, and INP
What Core Web Vitals measure, the LCP, CLS, and INP thresholds that count as good, and practical ways to improve each one without guesswork.
