AISA and Yoast SEO: together, or just one?
The short answer: Yoast checks how you write, AISA fixes what you've already written. They don't have to be alternatives: AISA writes into Yoast's own fields, so you can run both. Here are the facts side by side, where Yoast wins, where AISA wins and how to choose without throwing anything away.
Published: September 26, 2026 · Both plugins' data read on 09/26/2026 from official sources
Two different jobs
Yoast SEO The most widely used SEO suite
More than 10 million active installs. In the free plugin: SEO and readability analysis as you write, sitemaps, schema, llms.txt, Search Console data through Site Kit by Google. Premium adds the AI features, the redirect manager, Local, News and Video SEO.
AISA Data Optimization, GEO and MCP
It doesn't help you write an article from scratch: it optimizes everything you've already published, hundreds of pages at a time, for Google and for AI answer engines. It works on its own or inside Yoast, writing into Yoast's fields. And it connects to your AI assistant over MCP.
Side by side
Documented features only. For Yoast: official yoast.com and wordpress.org pages read on September 26, 2026, MCP and GEO rows updated on October 7, 2026; for AISA: version 2.0.4 as published on WordPress.org.

Where Yoast wins
- Maturity. More than 10 million sites, 59 interface languages, 24/7 support in Premium. AISA has been on WordPress.org since August 2026.
- Analysis as you write. Real-time readability checks, even in the free plugin; inclusive language checks (English only) come with Premium. From 2.0.2 AISA measures readability as you write too, with Gulpease for Italian; Yoast still covers many more languages and highlights sentences in the text.
- Search Console and Analytics in the dashboard, free through Site Kit by Google. AISA imports Search Console data from CSV.
- A very complete Premium: redirect manager with CSV, Local, News and Video SEO included, Bulk Editor with AI.
- AI without keys. If you don't want to manage API keys, AI is included in the subscription. In AISA the same convenience comes only with AISA Cloud.
- Brand monitoring in AI answers. With Yoast SEO AI+ ($358.80/year + VAT), AI Brand Insights checks every week how ChatGPT, Perplexity, Gemini and Claude talk about your brand, with sentiment and a competitor comparison. AISA today runs on-demand scans with your own keys.
Where AISA wins
It optimizes what you've already written
One-Click works on the whole site in the background: titles, descriptions, keyphrases, alt text, categories. Yoast helps you write the next page well; AISA fixes the hundreds you already have.
You pick the keys and the model
Eight providers, the WordPress AI connector or AISA Cloud. You pay the provider directly, at the provider's price, and choose the model for cost or quality.
Works on local and staging sites
AISA's AI features work on a site that isn't public. Yoast's, according to its own FAQ, need a site reachable from the internet.
An MCP server inside the plugin
From Claude you ask for a page audit, the fix and a re-check. Reading tools are in Free, writing tools in Premium. ChatGPT connects through a third-party OAuth connector.
Built for AI answers
Beyond llms.txt: an AI Search Context for each page, questions and answers approved by hand, structured data grafted into Yoast's graph.
Your brand's voice, in the right language
Brand Context and Writing DNA make copy sound like the rest of the site, in the page's real language. Plus SEO Rotation, and AISA's data kept out of WordPress autoload (0 KB on our test site).
Together, or just one?
Keep Yoast and add AISA
The site already runs Yoast, you like the analysis as you write and the Site Kit data. AISA writes into Yoast's fields with no duplicates: Yoast stays in charge of the output and AISA's schema is grafted into its graph. You add bulk optimization, your own keys, local work and MCP.
AISA only
A new site or one without an SEO plugin, and you don't need Search Console in the dashboard. One plugin for titles and meta, schema, llms.txt, redirects, sitemap and IndexNow, Local SEO and AI with your own keys.
Yoast Premium only
You want AI with no keys or credits, titles, descriptions and summaries page by page are enough, and the team works by the readability lights with 24/7 support.
Yoast checks how you write; AISA fixes what you've already written. Together they cover both halves.
What it costs, for one site
Yoast SEO Premium: €118.80 per year, excluding VAT (yoast.com product page, read on 09/26/2026). Yoast WooCommerce SEO, which includes Premium: €178.80 per year, excluding VAT.
AISA Solo (one site, your own keys): €79.99; with the FOUNDER50 code the first year costs €39.99, then renewal is €19.99 per year. The discount applies to the first payment, for the first 500 licenses. The Free version, on WordPress.org, includes manual optimization of all your content and the MCP reading tools.
If you keep Yoast and add AISA, you pay for both: it makes sense when bulk optimization and working from your AI assistant save you hours.
Frequently asked questions
Do I have to uninstall Yoast?
No. AISA detects Yoast and writes into its fields: you'll find titles, descriptions and keyphrases where you always have. If one day you want to move to AISA alone, the SEO transfer tool moves the data.
Does it work on a local site?
Yes. AISA calls the AI provider from your site with your keys, so it also works locally or on staging.
Does it work with ChatGPT?
AISA connects to Claude directly, with a WordPress application password. ChatGPT requires OAuth, so you go through a third-party connector such as Easy MCP AI. Either way you work one page at a time; for the whole site there's One-Click.
What do I get with AISA Free?
Page-by-page SEO generation with no quotas, SEO Doctor, llms.txt, schema, redirects, Local SEO, Brand Context and the MCP reading tools. Premium adds One-Click, Bulk, Rotation, scheduling and the MCP writing tools.
