WordPress runs roughly four in ten websites. That popularity is why there is a plugin for everything — and also why it is the most attacked platform on the web.
These guides cover the parts that matter in practice: getting a site built, keeping it secure, making it fast, and fixing it when it breaks.
The five things to get right on day one
Each of these is painful to change later, and skipping them causes most of the problems people write in about:
- Permalinks set to "Post name" before publishing anything. Changing this later breaks every existing URL.
- An admin username that is not "admin". Every automated attack tries that name first.
- HTTPS from the start. Installing over HTTP stores
http://links throughout the database, which then have to be cleaned out. - The "Discourage search engines" box unticked on launch day. Forgetting this is the single most common reason a new site never appears in Google.
- Working backups, tested once. An untested backup is a guess.
Is WordPress the right choice?
Not always, and it is worth being honest about it.
It suits you if the site gains content regularly, or needs forms, a shop or memberships. The plugin ecosystem genuinely saves months of work.
It suits you less if the site is five pages that never change. WordPress carries a lot of machinery you would never use, and every plugin is something else to keep patched. Plain HTML loads faster, costs less and has nothing to update.
Why WordPress sites get slow
Almost always the same three things, in this order:
- Uncompressed images. On most sites they are 60 to 80 percent of the page weight. A phone photo is often 4 MB when it should be under 200 KB.
- No caching. Without it, WordPress rebuilds every page from the database on every single visit.
- Too many plugins. Each one adds code to every page load, whether that page uses it or not.
Switching to PHP 8.1 or newer is the easiest gain of all — roughly twice as fast as PHP 7.4, free, and takes a minute in cPanel.
When something breaks
The white screen of death is a PHP fatal error with error display switched off. Before changing anything, turn on WP_DEBUG_LOG and read what actually failed. Guessing at plugin conflicts without reading the log wastes hours.
