Learn Technical SEO through practical guides on crawling, indexing, rendering, XML sitemaps, robots.txt, canonical tags, Core Web Vitals, structured data, and website architecture.
Core Web Vitals are Google’s three field metrics for measuring real-world page experience: loading speed, responsiveness, and visual stability. Since Interaction to Next Paint (INP) replaced First Input Delay (FID) in March 2024, these metrics have taken their current form. This guide breaks down what each one measures, the thresholds you need to hit, and…
International SEO lives or dies on one small, easily-broken attribute: hreflang. It tells search engines which language and regional version of a page to show a given user — and when it’s implemented incorrectly, the wrong audience sees the wrong page, or worse, Google ignores the signal entirely. This guide covers how hreflang works, how…
Redirects tell browsers and search engines that a URL has moved. Used correctly, they preserve rankings, protect user experience, and keep link equity flowing. Used incorrectly, they can silently bleed traffic, dilute crawl budget, and confuse Google about which URL to index. This guide breaks down the four redirect types every SEO and developer should…
A URL is more than an address — it’s a ranking signal, a trust indicator, and a crawl instruction rolled into one string. Get the structure right, and you improve crawl efficiency, click-through rate, and how AI answer engines like Google AI Overviews cite your pages. Get it wrong, and you create duplicate-content sprawl that…
When a browser or app talks to a web server, the server replies with a three-digit number called an HTTP status code. That number tells the client — instantly — whether the request worked, failed, or needs another step. Understanding these codes matters for developers debugging APIs, and for SEOs diagnosing crawl errors, redirect chains,…
Search engines don’t automatically know how you want each page on your site treated. The meta robots tag fixes that gap — it’s a small piece of HTML that tells crawlers whether to index a page, follow its links, cache it, or show it in search results at all. Get it wrong, and you can…
What Is a Canonical Tag? A canonical tag is a small piece of HTML code that tells search engines which version of a page should be treated as the “master” copy when multiple URLs contain the same or very similar content. It lives in the <head> section of a page and looks like this: <link…
Think of an XML sitemap as a note you hand to Google before it even starts exploring your site: “Here’s every page I care about, and here’s when I last touched it.” <cite index=”14-1″>A sitemap is a file where you provide information about the pages, videos, and other files on your site, and the relationships…
What It Actually Is A robots.txt file is a plain text file sitting at your site’s root (yoursite.com/robots.txt) that tells search engine crawlers which URLs they’re allowed to request. Its main job is to prevent your site from being overloaded with crawler requests — it was never designed to keep pages out of Google’s index….
