What is HTTP?

The protocol used to transfer information across the web.

In plain English

HTTP is the set of rules browsers and servers use to talk. The browser asks for a resource, the server answers with a status and, usually, the content. Every page load is a stack of these exchanges.

The part that matters for marketing is the status code. It tells browsers and crawlers whether the page exists, has moved, or has failed, and that determines what gets indexed.

What to know

Request and response
A browser requests a URL, the server responds with a status code, headers and a body. Headers carry instructions about caching, security and indexing.
Status codes carry meaning
200 means fine, 301 means permanently moved, 302 means temporarily moved, 404 means not found, 5xx means the server failed. Search engines act on these literally.
Redirects preserve value
A 301 tells crawlers the page moved for good and passes signals to the new address. Getting redirect types wrong during a migration loses rankings.
HTTPS is the secure version
Same protocol, encrypted. It is the expected default, and browsers mark plain HTTP as insecure.

Why it matters

Status codes are the layer where technical SEO problems usually appear. Pages returning 404 after a rebuild, soft 404s serving thin content, redirect chains from three site moves ago, 5xx errors during crawls. None of it is visible in the design, and all of it affects what gets indexed.

Common mistakes

×Using 302 temporary redirects for permanent moves.
×Building long redirect chains instead of pointing old URLs at the final destination.
×Letting removed pages return 200 with an empty template rather than a proper 404 or a redirect.
×Ignoring server errors that appear in crawl reports because the site looks fine in a browser.

FAQs

What is the difference between HTTP and HTTPS?

HTTPS is HTTP with encryption via an SSL certificate. It protects data in transit and is the expected standard for any site.

Which redirect should I use when moving a page?

A 301 for permanent moves, which is nearly always the case in a site migration. Reserve 302 for genuinely temporary situations.
