Frequently asked questions about TopicalSEO — the free WordPress AI SEO plugin.
TopicalSEO is a free, open-source WordPress plugin that uses NVIDIA's AI (via the NIM API) to automate the most time-consuming parts of SEO content strategy. It builds topical authority maps, generates full SEO articles, creates FAQ content with schema markup, and automates internal linking — all from within your WordPress dashboard.
Yes. The TopicalSEO plugin is completely free and open-source (GPL2 license). The only potential cost is the NVIDIA NIM API if you exceed the free tier. NVIDIA provides generous free credits that are more than sufficient to generate hundreds of articles and thousands of FAQs — many users never need to pay for API credits.
Yes, you need a free NVIDIA NIM API key from build.nvidia.com. Creating an account is free and no credit card is required. NVIDIA offers free inference credits for many models including Llama 4 Maverick, Llama 3.3 70B, and others. Most bloggers and small site owners will never exceed the free tier.
ZimmWriter is a standalone Windows desktop application that costs $9.99–$24.99/month. TopicalSEO is a free, native WordPress plugin. Key differences: TopicalSEO generates topical authority maps (ZimmWriter doesn't), auto-injects schema markup, fills Yoast/Rank Math meta fields automatically, and runs internal linking automatically on publish. ZimmWriter requires copy-pasting content into WordPress; TopicalSEO generates content directly into posts.
A topical authority map is a strategic content plan that covers all angles of a topic, signaling to Google that your site is a complete, expert resource. Based on Koray Tugberk's methodology, it groups content into pillar clusters and supporting subtopics. TopicalSEO generates:
The FAQ Generator doesn't just ask "what questions do people have?" It systematically generates questions across 12 distinct intent dimensions: Foundational, Mechanistic, Benefits, Risks, Practical How-To, Comparisons, Use Cases, Common Mistakes, Troubleshooting, Commercial Intent, Expert/Advanced, and Future Trends. This ensures every possible question a searcher might have is answered on your page — perfect for People Also Ask coverage and AI Overviews.
TopicalSEO automatically writes meta titles and descriptions to Yoast SEO (_yoast_wpseo_title, _yoast_wpseo_metadesc), Rank Math (rank_math_title, rank_math_description), and All in One SEO (_aioseo_title, _aioseo_description). It also saves to its own _tseo_meta fields as a fallback. If you switch SEO plugins later, the data is already there in multiple formats.
Absolutely. Both the Article Generator and FAQ Generator work on any existing WordPress post or page, not just ones created through TopicalSEO's topical maps. Simply open any post in the editor, find the TopicalSEO sidebar, enter your target keyword, and click Generate. The article or FAQ content will be written directly into your post.
Link Juice Mode is TopicalSEO's smart internal linking system. When you publish content within a topical cluster, it automatically creates contextual internal links between semantically related articles, with strategic emphasis on sending PageRank toward pillar pages. The anchors are selected by AI to be natural and contextually relevant — never keyword-stuffed. This builds a proper topical authority network that Google recognizes.
Generated articles are a minimum of 1,200 words, typically ranging from 1,200–2,000 words depending on the complexity of the topic and the AI model chosen. Articles include a proper H2/H3 heading structure, keyword placement in the first sentence, comparison tables, key facts sections, an embedded FAQ with structured data, and a natural, conversational writing style — no robotic AI filler phrases.
Yes. TopicalSEO adds a sidebar meta box to the Gutenberg block editor that appears when editing any post or page. From this sidebar you can trigger article generation, FAQ generation, choose the number of FAQs, select insert mode, and view the last generation time — all without leaving the editor screen. Classic Editor is also fully supported.
TopicalSEO generates original content via NVIDIA AI models each time — it is not spinning existing articles or using templates. However, as with any AI-generated content, we recommend reviewing and adding your own expertise, personal experience, and original insights before publishing. Google's guidelines focus on helpful, expert content regardless of how it was created. The best results come from using AI-generated content as a strong first draft that you refine with your unique knowledge.
Install TopicalSEO on your WordPress site and watch NVIDIA AI build your content strategy, write your articles, generate FAQ schemas, and link everything together — automatically.
