If you are choosing between All in One SEO vs Yoast in September 2026, here is the short version: Yoast SEO is the safer pick for a single-site blogger who wants guidance and never wants to touch settings, AIOSEO is the better value for agencies and multi-site owners who need redirects, a link assistant and client management in one licence, and Rank Math beats both on free-tier features. I run this site on Rank Math Pro, and I will explain why below, but I have set up all three on client sites this year and none of them will hold a site back.
- Yoast SEO Premium is $118.80/year for one site with no first-year discount; AIOSEO starts at $49.50 for year one and renews at $99; Rank Math Pro is $95.88/year (€) for unlimited personal sites (all as of September 2026).
- Yoast has 10M+ active installs, Rank Math 4M+, AIOSEO 2M+. Install count tells you about support forums and theme compatibility, not ranking power.
- Rank Math gives you redirects, a 404 monitor, 18 schema types and llms.txt for free. Yoast and AIOSEO both lock redirects behind paid tiers.
- Switching plugins is safe: all three import titles, descriptions, canonicals and robots meta from each other. Redirects and schema need a manual check.
- No SEO plugin ranks your site. Pick the one your team will actually use correctly, then spend the saved hours on content and links.
All in One SEO vs Yoast at a glance: price, installs and what each does best
In any AIOSEO vs Yoast comparison the core job is identical: titles, meta descriptions, Open Graph, sitemaps, schema and indexing controls. The differences are in the paid tiers, the interface and how much the plugin nags you.
Yoast SEO (version 28.4, updated every two weeks) is the most installed SEO plugin on wordpress.org with 10M+ active installs and a 4.8-star rating from around 27,800 reviews. AIOSEO (version 5.0.1) sits at 2M+ installs with 4.7 stars. Rank Math has 4M+ installs and 4.8 stars, so the “aioseo vs yoast vs rank math” ranking by popularity is Yoast, Rank Math, AIOSEO.
Pricing changed a lot in the last 18 months. Yoast folded its Local, News and Video add-ons into Premium, which now costs $118.80/year per site, with a WooCommerce bundle at $178.80 and an AI+ tier at $358.80. Yoast does not discount year one.
AIOSEO sells Basic ($99/year, 1 site), Plus ($199, 3 sites), Pro ($399, 10 sites) and Elite ($599, 100 sites), all 50% off for the first year. Rank Math Pro is €95.88/year for unlimited personal sites, Business €299.88 for 100 client sites, Agency €659.88 for 500. I compared Rank Math’s tiers in Rank Math free vs Pro.
Feature comparison table: free vs premium for Yoast, AIOSEO and Rank Math
This table is based on the plugin pages and pricing matrices as of September 2026. “Free” means the wordpress.org version; “Paid” means the entry paid tier unless noted.
| Feature | Yoast Free | Yoast Premium ($118.80) | AIOSEO Free | AIOSEO Basic to Elite ($99 to $599) | Rank Math Free | Rank Math Pro (€95.88) |
|---|---|---|---|---|---|---|
| Focus keywords per post | 1 | Multiple + synonyms | Unlimited | Unlimited (10 TruSEO scored) | Unlimited | Unlimited |
| Redirect manager | No | Yes (301/302/410, regex) | No | Pro and Elite only | Yes | Yes + auto post redirects |
| 404 monitor | No | Partial (via redirects log) | No | Pro and Elite | Yes | Yes |
| Schema types | Basic (Article, Org, Person, FAQ, HowTo blocks) | Same + News/Local/Video | Basic Article, Org, Local (Plus+) | Full schema generator, custom schema | 18 types | 840+ types, custom schema builder |
| Internal link suggestions | No | Yes + orphaned content filter | No | Link Assistant (Pro and Elite) | No | AI Link Genius (uses Content AI credits) |
| IndexNow | No | Yes | Free add-on | Yes | Yes (Instant Indexing) | Yes |
| llms.txt | Yes, one click | Yes | Yes (add-on) | Yes | Yes | Yes |
| AI title/meta generation | Limited free credits | Bulk generation, AI Content Planner | No | 10k to 200k AI credits/year | Content AI trial | Content AI trial (paid credits after) |
| Rank tracking | No (Wincher integration) | No (Wincher integration) | No | Search Statistics (GSC-based) | GSC analytics module | 500 to 50,000 tracked keywords |
| WooCommerce SEO | Basic | Bundle at $178.80 | Basic | Plus and above | Basic | Included |
| News sitemap | No | Included | No | Pro and Elite | No | Included |
| Multi-site licence | n/a | 1 site per licence | n/a | 1 / 3 / 10 / 100 sites | n/a | Unlimited personal sites |
Two things jump out. Rank Math’s free tier does what Yoast Premium and AIOSEO Pro charge for on redirects and 404 logging. And Yoast’s $118.80 buys one site, so five sites cost $594/year on Yoast versus $399 renewal on AIOSEO Pro or €95.88 on Rank Math Pro.
Where Yoast still wins in 2026
Yoast’s content analysis is the most polished of the three. The readability score, the transition-word check and the keyphrase distribution bar are things a new writer can follow without training. Since version 28 the free plugin also generates llms.txt in one click, and Premium’s bulk editor (28.4, released 1 September 2026) lets you filter every post with a weak title or missing description and fix them from one screen.
Yoast also has the deepest theme and page-builder compatibility. If you run an older theme or a niche plugin that hooks into the SEO title, Yoast is what those developers tested against. The weakness is cost per site and the paywall on redirects. If you are already on Yoast, my Yoast SEO tutorial covers the settings that matter.
Where AIOSEO wins
AIOSEO’s strongest argument is the agency licence. Elite covers 100 sites for $599 ($299.50 year one) and includes client management, content decay tracking, a redirect manager with full-site redirects, and the Link Assistant, which crawls your own content and suggests internal links with one-click insertion. Yoast Premium’s internal linking suggestions are good, but Link Assistant reports on inbound, outbound and orphaned pages in a single table.
Version 5.0 rebuilt the TruSEO analyser with spell checking and AI suggestions, and every paid tier includes AI credits for titles, descriptions and FAQs. The weakness is upsell noise: locked features sit in the free menu, the settings are busier than Yoast’s, and the smaller install base means thinner forum answers. Setup details are in my All in One SEO plugin guide.
Where Rank Math wins, and why this site runs Rank Math Pro
I moved this site to Rank Math Pro in 2024 and have not looked back. The reasons are practical: the free redirect manager and 404 monitor, a schema builder that lets me add custom JSON-LD without a code snippet, unlimited sites on one Pro licence, and a modular design where I can switch off everything I do not use. On a fresh install with only the modules I need, it adds fewer scripts to the admin than either competitor.
Rank Math is not perfect. Content AI credits run out fast, the upgrade prompts are as persistent as AIOSEO’s, and the September 2026 update paused a new “Support Agent” feature after users questioned how it requested site access. Read changelogs before updating production. For a walkthrough see my Rank Math tutorial; for the head-to-head, Rank Math vs Yoast.
Performance and bloat: what each plugin actually loads
None of the three will wreck your Core Web Vitals on their own, because they output HTML in the head rather than front-end JavaScript. The difference shows up in three places.
- Front-end: all three add a schema graph and a few KB of meta tags. Rank Math adds a table of contents script only if you enable it.
- Admin: AIOSEO and Rank Math load React dashboards that feel slow on cheap shared hosting. Yoast’s sidebar is lighter, but its AI features call an external API per generation.
- Database: Rank Math’s analytics module stores GSC data locally and the table grows; turn it off if unused. AIOSEO’s SEO Revisions do the same on Plus and above.
In audits I have run for agency clients on shared hosting, the SEO plugin was never the biggest speed problem. The page builder, unoptimised images and a missing cache layer were. Fix those first with my WordPress speed plugins roundup, then pick the SEO plugin on features.
Who should pick which: four verdicts
Beginner blogger with one site
Yoast Free or Rank Math Free. Yoast if you want traffic-light scores that teach on-page SEO and you rarely delete posts. Rank Math if you want redirects and 404 tracking without paying. Do not buy AIOSEO Basic at $99 renewal for one blog; it lacks redirects.
Agency managing 10 to 100 client sites
AIOSEO Elite ($599, 100 sites) for client management, white-label options and content decay alerts, or Rank Math Business (€299.88, 100 client sites) for white-labelled reports and 10,000 tracked keywords at a lower price. Yoast at $118.80 per site is the most expensive option at scale by a wide margin.
WooCommerce store
Yoast Premium with the WooCommerce bundle ($178.80) or Rank Math Pro (€95.88, WooCommerce module included). Yoast has the longest record with product schema, variants and breadcrumbs; Rank Math covers the same ground for less and adds GTIN and brand fields. AIOSEO needs Plus ($199) or higher.
News site or high-volume publisher
Yoast Premium or Rank Math Pro. Both include a Google News sitemap, NewsArticle schema and IndexNow. Yoast’s 28.4 bulk editor suits a newsroom publishing 30 posts a day that needs to catch missing meta. Rank Math Pro adds a video sitemap and Google Indexing API support. AIOSEO Pro has the news sitemap but costs more per site.
How to switch plugins without losing your meta data
All three plugins import from the other two, and the migration takes under 15 minutes on a normal site. Here is the order I follow.
- Take a full backup. Export current redirects to CSV if the plugin supports it.
- Install and activate the new plugin. Keep the old one active for now.
- Run the importer (Rank Math: Tools > Import & Export; AIOSEO: Tools > Import/Export; Yoast: SEO > Tools). All three import titles, descriptions, canonicals, robots meta and Open Graph fields.
- Spot-check 10 posts, including one with a custom canonical and one set to noindex.
- Re-create redirects. Rank Math and AIOSEO import Yoast Premium redirects; Yoast only imports from CSV.
- Test schema on a post and a product with Google’s Rich Results Test. Yoast FAQ and HowTo blocks do not carry over and must be rebuilt.
- Regenerate the sitemap, resubmit it in Search Console, then deactivate and delete the old plugin.
Google’s redirects guidance and structured data introduction are the references I keep open during a migration. If 404s appear afterwards, my 404 fix guide covers the cleanup.
Common mistakes I see with all three plugins
- Chasing a green light. I have seen posts with a red Yoast score outrank green ones because the red one matched intent. Use the score to catch missing basics, not as a target.
- Enabling every schema type. Article, FAQ, HowTo and Review on one post is a rich-result eligibility risk. Add schema that matches visible content; my schema markup for AEO guide has the rules.
- Leaving auto-generated meta descriptions on. AIOSEO and Rank Math fill the description from your excerpt. Better than nothing, not click-worthy.
- Running two SEO plugins at once. Duplicate titles, duplicate schema graphs, two sitemaps. Finish the migration, then delete the old plugin.
- Ignoring archive noindex settings. Yoast indexes author and date archives by default; Rank Math’s wizard asks. Noindex what you do not want ranking.
My verdict on the best WordPress SEO plugin
For a single blog, Yoast Free or Rank Math Free are both fine and cost nothing. For anyone managing more than three sites, Rank Math Pro is the best value in the market as of September 2026, which is why this site runs it. AIOSEO is the right pick if you want the agency tooling and Link Assistant in one licence and are happy to pay for Pro or Elite. Yoast remains the safest choice when compatibility matters more than price, and its bulk editor and WooCommerce bundle are strong for publishers and stores.
Whichever you install, the plugin is worth maybe 5% of your ranking outcome. The other 95% is keyword research, content that matches intent and links. Spend accordingly.
FAQ
Is All in One SEO better than Yoast?
Not universally. AIOSEO gives more features per dollar on multi-site licences and a stronger internal-link tool. Yoast has better content analysis and wider compatibility. On one site, Yoast vs All in One SEO is close on price, and AIOSEO Basic lacks redirects.
Which is better, Yoast or Rank Math or AIOSEO?
Rank Math offers the most for free, Yoast has the largest install base and most polished editor, and AIOSEO has the best agency licence. My picks: Rank Math Pro for multi-site value, Yoast for beginners and WooCommerce, AIOSEO for agencies that want client management built in.
Can I switch from Yoast to All in One SEO without losing rankings?
Yes. AIOSEO’s importer pulls titles, descriptions, canonicals, robots meta and Open Graph data from Yoast. Rebuild redirects and block-based schema, resubmit the sitemap, and rankings should hold.
Do I need to pay for an SEO plugin?
Most single-site owners do not. Pay when you need redirects (Yoast, AIOSEO), multiple keywords per post (Yoast), a news sitemap, a rank tracker, or a multi-site licence. Rank Math Free covers redirects for nothing.
Does Yoast or AIOSEO support llms.txt and IndexNow?
Both do as of September 2026. Yoast generates llms.txt free and includes IndexNow in Premium. AIOSEO offers both as free add-ons. Rank Math supports both free. No AI system promises to read llms.txt, but enabling it costs nothing.
