🔍 What Are the NLP Keywords and Missing Keywords Modules?
When OTTO is active on a page, it may inject two hidden on-page modules to strengthen your content's semantic relevance:
- NLP Keywords Module (Meta Keywords Issues fix): Inserts a hidden block of semantically relevant terms that help search engines understand your page's topical context. This addresses gaps identified in OTTO's Meta Keywords Issues audit check.
- Missing Keywords Module (Missing Keywords Issues fix): Injects additional keyword phrases that were detected as absent from your page content. This addresses OTTO's Missing Keywords Issues audit check.
Both modules are rendered in a visually hidden format — they are not visible to human visitors but are readable by search engine crawlers. Their purpose is to reinforce topical signals without requiring manual edits to your CMS content.
⚠️ Do Hidden Keyword Modules Cause SEO Harm?
This is a common concern, and it deserves a direct answer.
OTTO's hidden modules are designed to be crawler-safe. They use standard HTML that search engines can read, and the keywords injected are directly derived from your page's existing topic and target terms — not unrelated or excessive phrases. However, there are situations where you should review or disable these modules:
- Your page already has strong keyword coverage and adding more terms could create an unnaturally high keyword density.
- Your site operates in a niche where any form of hidden content could attract manual review scrutiny.
- You have manually audited your page and confirmed the injected terms are redundant or mismatched.
Keyword stuffing risk: OTTO limits injected terms to those identified in its audit, so accidental over-optimisation is uncommon. That said, if your page content already covers the flagged keywords naturally, disabling the module is a safe and recommended choice rather than duplicating signals.
✏️ How to Manage an OTTO-Injected Module
If you want to review or disable an active NLP Keywords or Missing Keywords module, navigate to the OTTO section of your Search Atlas dashboard. From there, locate the affected site and the specific page where the fix is applied. You should be able to see the active fixes associated with that page — look for entries corresponding to Meta Keywords Issues or Missing Keywords Issues. You can turn off an individual fix from within that page's fix list if you determine the injected content is no longer needed or is causing unwanted keyword density.
If you are unsure where to find these controls in your current dashboard view, or if the option to disable a specific fix is not visible to you, please reach out to our support team for guided assistance — they can walk you through the exact steps for your account.
