If you’re picking between All in One SEO vs Yoast right now, here’s the short version: Yoast is the better default for a single content-heavy site, and All in One SEO wins the moment you’re managing more than two or three WordPress installs. The reason isn’t features. Both plugins now do the same core job. The reason is licensing, and almost nobody talks about that part honestly.
We manage WordPress SEO for client sites across Karachi and beyond, which means we’ve had both plugins active on different projects at the same time. That’s the lens this comparison comes from, not a spec sheet.
The Real Difference Isn’t the Feature List Anymore
Back in 2020 there was a genuine gap. Yoast had content analysis and readability scoring that All in One SEO simply didn’t offer. That gap is gone. Both plugins now ship:
- XML sitemaps
- Schema markup (Article, FAQ, Product, HowTo)
- Meta title and description editing
- Social media preview cards
- Redirect management (paid tiers)
- AI-assisted title and description suggestions
So if you’re comparing these two purely on a checklist, you’ll end up going in circles because the checklists match almost line for line. The actual decision comes down to three things: how the plugin is priced, what it does with AI in 2026, and how heavy it is on your site.
All in One SEO vs Yoast: Pricing in 2026 (This Is Where It Actually Matters)
This is the part most comparison posts either skip or get wrong.
| Feature | Yoast SEO | All in One SEO (AIOSEO) |
|---|---|---|
| Basic Price | ~$118.80/year | ~$49.60/year (Basic) |
| Top Tier Price | Same (no separate multi-site tier) | ~$299.50/year (Elite) |
| Sites Covered (Top Tier) | 1 site | Up to 100 sites |
| Licensing Model | Per-site license | One license for multiple domains |
| Multi-Site Support | Limited | Strong |
| Agency Friendly | No | Yes |
| Best For | Single content-heavy website | Agencies & multi-site owners |
| Cost Efficiency for Multiple Sites | Low | High |
| Scalability | Low | High |
| Domain Management | Separate license for each site | Centralized under one license |
Yoast SEO Premium is licensed per site. One license, one domain. If you’re running one blog, that’s a fair number. If you’re an agency or you run five sites, you’re paying that five times over, so roughly $594/year for five domains with no bundling.
All in One SEO doesn’t work that way. Its Basic plan covers a single site, but the Pro tier (roughly $199.50/year) covers up to 10 sites under one license, and the Elite tier stretches to 100 sites. For anyone managing a portfolio of client sites, that structure alone makes All in One SEO cheaper by a wide margin the moment you cross two or three domains.
If you’re a solo blogger with one WordPress site, this difference barely registers. If you’re an agency, it’s the single biggest factor in this whole comparison, bigger than any feature on either list.
Feature Differences Worth Actually Knowing About
A few things genuinely separate the two, beyond pricing:
Internal linking suggestions. Yoast’s implementation here is still the strongest of any WordPress SEO plugin we’ve used. It flags orphaned pages and suggests where to link from existing content, and it does this reasonably well even on free.
AI visibility tracking. All in One SEO added a feature that checks whether your content is showing up in ChatGPT and Gemini answers, something Yoast doesn’t currently offer. Whether that matters to you depends on how much AI search traffic your niche actually gets, but it’s a real, specific feature gap, not a marketing claim.
Redirect manager on free. Neither plugin includes this for free. If 404 handling matters to you and you don’t want to pay for either plugin, you’d need a separate free redirect plugin regardless of which one you pick.
Site weight. Both plugins have been accused of slowing sites down, and both claims are true in specific cases and false in others. It depends far more on your hosting and how many other plugins you’re running than on which of these two you choose. Neither is meaningfully lighter than the other in 2026.
Which One Should You Actually Install?
Skip the “it depends on your needs” answer. Here’s a direct one:
- Single site, content-focused blog or small business site: Yoast. The internal linking tool and readability checks are worth the per-site cost when you only have one site to license.
- Agency or freelancer managing multiple client sites: All in One SEO. The multi-site licensing alone will save you hundreds of dollars a year once you pass two or three domains.
- Ecommerce store on WooCommerce: Both have dedicated WooCommerce features. Yoast’s WooCommerce SEO bundle and AIOSEO’s built-in WooCommerce support are close enough that this shouldn’t be your deciding factor, price and site count still should be.
- You’re not sure yet and just want something free that works: Either free version covers the fundamentals fine. Don’t overthink this one until you actually need the paid features.
Can You Run Both at the Same Time?
No. Don’t. Both plugins write meta tags, generate sitemaps and inject schema markup, and running two SEO plugins simultaneously creates duplicate sitemaps and conflicting schema output, which confuses Google more than it helps you. If you’re switching from one to the other, deactivate and delete the old plugin after moving your settings over, don’t leave both active “just in case.”
Switching from All in One SEO to Yoast is more or less painless: Yoast has a built-in importer under Tools that pulls over your existing meta titles, descriptions and settings automatically. Going the other direction requires more manual re-entry since All in One SEO’s import tool is less complete, so budget some time if you’re moving that way.
FAQs
Q1. Is All in One SEO better than Yoast?
For a single site, no, Yoast’s internal linking and readability tools edge it out. For anyone running multiple WordPress sites, All in One SEO’s licensing makes it the more practical choice regardless of the feature list.
Q2. Which plugin has more features in the free version?
Yoast’s free tier includes more out of the box, particularly around content analysis and readability. All in One SEO’s free tier covers the technical basics (sitemaps, meta tags) but holds back more of its feature set behind paid tiers.
Q3. Do I need the paid version of either plugin?
Not immediately. Both free versions handle the fundamentals: meta tags, sitemaps and basic schema. Upgrade only once you specifically need redirect management, internal linking suggestions or multi-keyword optimization.
Q4. Can I switch from Yoast to All in One SEO without losing my SEO data?
Your meta titles, descriptions and focus keywords are stored in the database and generally survive a plugin switch, but the transfer isn’t always clean depending on which import tool you use. Back up your database before switching either way.
Q5. Is Rank Math a better option than All in One SEO and Yoast?
That’s a separate comparison with its own pricing and feature trade-offs. This guide focuses specifically on All in One SEO vs Yoast, since that’s the decision most WordPress users are actually stuck on.
