A Plugin vs a Standalone Tool
Yoast SEO is the most popular WordPress SEO plugin with over 12 million active installations. It helps WordPress users optimize their posts for search engines by analyzing content against a single “focus keyphrase” you manually enter. It checks whether that keyphrase appears in your title, meta description, headings, URL, and body text.
The AllTools Keyword Extractor takes the opposite approach. Instead of asking YOU to tell IT what the focus keyword is, it analyzes your text and tells YOU what the most important keywords are. It works with any text from any platform — not just WordPress — and extracts multiple keywords ranked by statistical relevance.
These are fundamentally different tools solving related but distinct problems.
Quick Summary
Choose Yoast if: You run a WordPress site and want real-time SEO feedback while editing posts. You already know your target keyword and want to check whether your content is optimized for it.
Choose AllTools if: You want to discover which keywords your text actually emphasizes. You work outside WordPress (or in addition to it). You need multiple keywords extracted, not just a single focus keyphrase analyzed.

The Core Problem: Yoast Doesn’t Extract Keywords
Yoast’s biggest limitation for keyword analysis is that it doesn’t extract keywords at all. It requires you to type in a “focus keyphrase” before it can do anything. The plugin then checks whether your post mentions that exact phrase in the right places — title, first paragraph, headings, meta description, URL slug.
This creates a chicken-and-egg problem. How do you know what your focus keyphrase should be? If you’ve already done keyword research with another tool, Yoast validates your optimization. But if you’re looking at a piece of text and wondering “what are the main keywords here?” — Yoast can’t help.
The AllTools Keyword Extractor solves this directly. Paste your text, and it returns the 5, 10, 15, or 20 most statistically significant keywords, ranked by relevance. You can then use these as your Yoast focus keyphrases, as meta keywords, or as social media hashtags.
Yoast Premium: $99/Year for Multiple Keywords
In the free version, Yoast only lets you set one focus keyphrase per post. If you want to optimize for additional related keywords, you need Yoast Premium at $99/year. Premium allows up to 5 keyphrases per post, along with features like an internal linking suggestion tool and redirect manager.
AllTools extracts up to 20 keywords for free, from any text, with no annual subscription. And those 20 keywords are automatically identified — you don’t need to guess or research them first.
The WordPress Lock-In
Yoast only works inside the WordPress editor. If your content lives anywhere else — Shopify, Webflow, Ghost, static sites, Google Docs, PDFs, email newsletters — Yoast cannot analyze it.
The AllTools Keyword Extractor works with any text. Copy content from any source, paste it in, and extract keywords. This makes it useful for:
- Analyzing competitor content — paste a competitor’s blog post to see what keywords they emphasize
- Reviewing guest posts — check what keywords a submitted article focuses on before publishing
- Auditing non-WordPress content — product pages on Shopify, landing pages on Webflow, articles on Medium
- Analyzing offline content — research papers, reports, transcripts
A Workflow That Uses Both
If you run a WordPress site with Yoast, the AllTools Keyword Extractor complements it rather than replacing it.
- Write your draft in the WordPress editor
- Copy the text and paste it into the Keyword Extractor
- Review the extracted keywords — the top-ranked keyword is your best candidate for Yoast’s focus keyphrase
- Enter that keyword in Yoast and follow its optimization suggestions
- Check keyword density with the Keyword Density Checker for a more granular view than Yoast’s traffic light system
- Export remaining keywords as meta keywords using the one-click export
This gives you the best of both worlds: AllTools discovers the keywords, Yoast validates the on-page optimization, and you get hashtag and meta exports that Yoast doesn’t provide.
Where Yoast Wins
Yoast has genuine advantages for WordPress users:
- Real-time editing feedback — the traffic light system updates as you type, giving immediate guidance on keyword placement, readability, and content structure
- Schema markup — Yoast generates structured data (Article, FAQ, HowTo) automatically within WordPress
- XML sitemaps — Yoast manages your WordPress sitemap with no additional plugin
- Redirect manager (Premium) — handle URL changes and 404s from within WordPress
- Internal linking suggestions (Premium) — recommends related posts to link to while editing
These features are tightly integrated with the WordPress editing experience in a way that a standalone tool cannot replicate.
Where AllTools Wins
- Keyword discovery — AllTools finds keywords automatically; Yoast needs you to provide them
- Multiple keywords for free — extract up to 20 keywords at no cost vs. 1 focus keyphrase on Yoast Free or 5 on Premium
- Platform independence — works with text from any source, not just WordPress
- Hashtag export — convert keywords to social media hashtags with one click
- Meta keyword export — comma-separated format ready for any CMS
- Multilingual support — 9 languages with dedicated stopword lists
- Privacy — text never leaves your browser; though Yoast also processes locally within WordPress, your content already lives on that server
