You don't need all 22. Match the plugin to the problem. Start with one SEO suite for the basics, Google Site Kit to see your search data, one caching plugin for speed and one image optimiser for heavy images. Add the rest only when you hit that exact problem.
Most plugin lists are sorted by popularity, which doesn't help when your actual problem is a slow page or a messy sitemap. So this guide flips it. Each section starts with a problem you might have, then lists the free WordPress plugins that fix it. One rule applies everywhere: pick one plugin per job. Two SEO suites or two caching plugins cause conflicts, not extra rankings.
"Free" often means a free core version or a limited free tier, so check each plugin's WordPress.org page for current limits. Take a backup before installing anything, and test your key pages after each change.
Problem: my titles, meta tags and sitemap are a mess
Choose one SEO suite. It handles titles, meta descriptions, sitemaps and robots settings.
1. Rank Math. A generous free version with multiple focus keywords and a built-in redirect manager. A strong all-rounder if you want features without paying.
2. Yoast SEO. The most familiar name, with clear feedback and endless tutorials. Friendly for beginners.
3. All in One SEO (AIOSEO). A guided setup wizard and a tidy dashboard that make the first setup painless.
4. SEOPress. Lightweight and ad-light, with a clean interface. Some extras sit in the paid version.
5. The SEO Framework. Smart automatic defaults, so there's very little to configure.
Problem: I can't see what Google sees
6. Google Site Kit. Google's official plugin. It shows Search Console and Analytics data inside your dashboard.
7. IndexNow Plugin. Automatically submits new and updated pages to supporting search engines. Not every engine supports it, so keep your sitemap.
Problem: I want rich results
8. Schema & Structured Data for WP & AMP. A dedicated schema plugin whose basic version is free, with premium features as an upgrade. Your SEO suite may already output schema, so pick one source and avoid duplicates.
Problem: my links are broken or lonely
9. Redirection. Manages 301 redirects and logs 404 errors. Use it whenever you change a URL or delete a page that had traffic.
10. Internal Link Juicer. Builds internal links from keyword rules. The free version covers the basics.
11. Link Whisper Free. Suggests internal links while you write, with link reporting. The free version is a trimmed-down edition of the paid plugin.
12. Broken Link Checker by AIOSEO. Finds dead links. The free version is basic but handy for a monthly clean-up.
Problem: my pages are slow
Use one caching plugin, then add the helpers if you need them.
13. LiteSpeed Cache. Free and powerful on hosts that run LiteSpeed servers. Many settings, so change them slowly.
14. WP Fastest Cache. Simple page caching that's easy for beginners on any host. Advanced features are in the paid version.
15. Autoptimize. Minifies and defers CSS and JavaScript. Test menus and forms afterwards.
16. Asset CleanUp. Speeds up pages by unloading CSS and JavaScript files they don't need, and it works alongside caching and image plugins instead of replacing them. Pair it with a caching plugin.
Problem: my images are heavy
Use one image optimiser, then follow our image SEO guide for file names and alt text.
17. Smush. Compresses and lazy-loads images. The free version has limits, so read them first.
18. ShortPixel. Compresses images and can create WebP versions. The free plan has a monthly credit allowance.
19. EWWW Image Optimizer. The free version compresses on your own server, which suits anyone who dislikes credit limits.
20. Imagify. Compresses JPG, PNG and GIF images, and can be used free up to a monthly limit, so check the current allowance.
Problem: my long posts are hard to scan
21. Easy Table of Contents. Adds a clickable contents box so readers can jump to the part they need. It builds that box from your headings, so get your H1, H2 and H3 structure right first.
22. Web Stories for WordPress. A free editor built by Google for tappable, full-screen stories.
Which four should you install first?
Begin with one SEO suite (Rank Math or Yoast), Google Site Kit, one caching plugin that matches your host, and one image optimiser. That's four plugins out of twenty-two, and it covers most of what a small site needs. Add Redirection if your suite lacks a redirect manager, and bring in the others only when a real problem appears in Search Console or PageSpeed Insights.
Quick picks by goal (my suggestions)
Goal | Pick |
Most free features | Rank Math |
Easiest start | Yoast SEO or AIOSEO |
Search data | Google Site Kit |
Rich results | Schema & Structured Data for WP & AMP |
Redirects | Redirection |
Faster pages | LiteSpeed Cache (LiteSpeed hosts), otherwise WP Fastest Cache |
Lighter images | ShortPixel, Smush, EWWW or Imagify |
Readability | Easy Table of Contents |
A sensible setup order
Start with your SEO suite and its setup wizard. Connect Google Site Kit next so you have data from day one. Add caching, then image optimisation, testing your top pages after each step. Bring in links, schema and content tools only when you need them. Every few months, review the list and delete what you no longer use.
Mistakes that quietly hurt SEO
Running two SEO suites creates duplicate meta tags and competing sitemaps. Stacking caching plugins can serve stale or broken pages. Leaving unused plugins active adds code, update work and security risk. And installing a plugin isn't the same as configuring it, so run the setup wizard, submit your sitemap and noindex thin pages such as tag archives.
Where Google Discover fits in
No plugin can promise a Discover spot. Google says content is eligible if it's indexed and meets its content policies, and that eligibility doesn't guarantee appearing. It also recommends compelling, high-quality images at least 1200 px wide, with the max-image-preview:large setting enabled, and warns against clickbait. Most SEO suites can add that robots tag, so open your page source, search for "max-image-preview" and confirm it's there. Use an original featured image, not your logo, and show a named author and a real updated date.
The takeaway
Fix problems, don't collect plugins. Install one, test it, and watch what changes in Search Console over the next few weeks. A fast site, clean basics and genuinely useful content will do more than any number of extras.
