The WordPress plugin directory has tens of thousands of free plugins, and in your first week every one of them looks essential. Social share buttons, popups, sliders, three different SEO tools, a “speed booster”… Before you know it you have 25 plugins, a slow dashboard, and an update notification every morning.
A new blog needs surprisingly few plugins. Here are the seven that earn their place, and five you can skip for now.
How to Judge Any Plugin in 60 Seconds
Before installing anything, check its WordPress.org page for:
- Last updated: within the last few months is ideal. Over a year is a warning sign.
- Active installations: a large user base usually means problems get noticed and fixed.
- Tested with your WordPress version: or at least a recent one.
- Reviews and support threads: are recent problems getting answered?
- Does your theme or host already do this? Many hosts include caching and backups, so you don’t need a second tool for the same job.
The 7 Plugins Worth Installing
1. An SEO plugin (Rank Math or Yoast SEO)
Lets you set page titles and meta descriptions, generates an XML sitemap, and handles basic schema markup. Pick one. Running two SEO plugins causes conflicts.
2. A caching plugin (only if your host doesn’t provide caching)
Caching saves ready-made copies of your pages so they load faster. LiteSpeed Cache (on LiteSpeed servers), WP Super Cache or W3 Total Cache are common free options. Many managed hosts include caching at the server level and ask you not to add a plugin. Check first.
3. A backup plugin (UpdraftPlus or similar)
Automatic backups stored off your server, in something like Google Drive or Dropbox. Your host’s backups are helpful, but if your hosting account itself has a problem, you want a copy somewhere else.
4. A security plugin (Wordfence, Solid Security or similar)
Adds login protection, a firewall and malware scanning. At minimum, you want login attempt limits and two-factor authentication for your admin account.
5. An anti-spam plugin (Akismet or Antispam Bee)
If comments are turned on, spam will arrive within days. These filter it automatically.
6. An image optimisation plugin (ShortPixel, Smush, EWWW or similar)
Compresses images and can convert them to modern formats like WebP. Images are usually the heaviest part of a blog page, so this is one of the easiest speed wins available.
7. A contact form plugin (WPForms Lite, Contact Form 7 or Fluent Forms)
You need a working contact page for readers, for brands, and for affiliate program applications. A simple form is enough.
Quick Reference
| Need | Example plugins (pick one) | Skip if… |
|---|---|---|
| SEO | Rank Math, Yoast SEO | Never skip |
| Caching | LiteSpeed Cache, WP Super Cache | Your host provides server caching |
| Backups | UpdraftPlus | Your host offers off-site backups you’ve tested |
| Security | Wordfence, Solid Security | Your host includes a firewall and malware scanning |
| Anti-spam | Akismet, Antispam Bee | Comments are disabled |
| Images | ShortPixel, Smush, EWWW | You compress images before uploading |
| Forms | WPForms Lite, Contact Form 7 | Never skip. You need a contact page |
5 Plugins You Can Skip (For Now)
1. Social share button plugins
Most new blogs get very few shares, and many share plugins load extra scripts on every page. Add a lightweight option later, once you actually get social traffic.
2. Slider plugins
Homepage sliders are heavy, often ignored by visitors, and can slow your page down. A single, clear hero section works better.
3. “All-in-one speed booster” plugins that overlap with your cache
Stacking several optimisation plugins often causes conflicts and broken layouts. One well-configured caching plugin plus image optimisation covers most of the gains.
4. Related posts plugins that query the database heavily
Some of these run expensive queries on every page load. Many themes include a related-posts feature, and manual internal links are often better anyway.
5. Popup and exit-intent plugins (until you have traffic)
With little traffic, a popup mostly annoys the few readers you have. Start with a simple opt-in form in your posts and add popups later if you need them.
Example: A Lean Plugin Setup for a New Blog
Here’s a full, sensible setup for a new affiliate blog on shared hosting:
- Rank Math (SEO)
- LiteSpeed Cache (the host runs LiteSpeed)
- UpdraftPlus (weekly backups to Google Drive)
- Wordfence (login security + firewall)
- Antispam Bee
- ShortPixel (image compression)
- WPForms Lite (contact form)
- Elementor (page builder for the homepage)
Eight plugins, each with a clear job, and no two doing the same thing.
How to Install a Plugin Safely
- Back up first, especially on a site with real content.
- Install from Plugins → Add New, which pulls from the official WordPress.org directory, or upload a zip from the developer’s own site.
- Activate it, then check your site on desktop and mobile. Look for layout changes or errors.
- Configure only what you need. Many plugins turn on extra features by default, so switch off anything you won’t use.
- If something breaks, deactivate the plugin you just added. If you can’t reach the dashboard, rename that plugin’s folder by FTP or in your host’s file manager.
Keep It Tidy
- Update plugins regularly. Outdated plugins are one of the most common ways WordPress sites get hacked.
- Delete plugins you’ve deactivated. Inactive plugins can still be a security risk.
- Review your plugin list every few months. If you can’t say what a plugin does, find out or remove it.
Takeaway
Every plugin should have one clear job that your theme and host don’t already do. Start with the seven basics, and add more only when you hit a real problem. For the other half of the equation, read what you lose with a free theme.
