CriterionCompetitorDeepSEOAnalysis
Core functionSemji is an AI-powered content SEO platform that analyses top-ranking pages for a target keyword using NLP and provides a "Content Score" indicating how well optimised the target page is compared to its competitors. The platform covers the full content production workflow: keyword and topic research, AI-assisted content brief creation, real-time content optimisation scoring as writers draft content (similar to Clearscope or Surfer SEO), integration with CMS platforms (WordPress, HubSpot, Drupal), team collaboration on content briefs and drafts, and performance tracking connecting content scores with actual ranking outcomes.A per-URL technical SEO and AI visibility auditor. Submit any URL for an on-demand audit: property-level JSON-LD structured data validation (including server-rendering detection), real CrUX field data (p75 LCP, CLS, INP from Chrome users), canonical tag correctness, robots.txt and AI crawler access, llms.txt presence, broken outbound links, and five-signal AI visibility scoring. Validates technical implementation quality of pages rather than optimising content depth.
Content scoring and NLP optimisationSemji's core feature is its Content Score — an NLP-based comparison of a page's content against the top-ranking pages for the target keyword. The score measures whether the page covers the same semantic terms, entities, questions, and topic clusters that top-ranking competitors cover. Writers receive real-time feedback as they draft: adding missing semantic terms increases the Content Score toward the target range associated with top-ranking content. The system identifies which specific topics and questions are covered by top-ranking pages but absent from the target page — prioritising the content additions most likely to improve ranking performance.No content scoring or NLP-based semantic analysis. DeepSEOAnalysis validates the technical implementation of pages — structured data quality, CWV performance, and AI visibility signals — rather than analysing content depth or semantic completeness. For content optimisation (ensuring a page covers the same topics and questions as top-ranking competitors), Semji, Clearscope, Surfer SEO, or MarketMuse address this phase; DeepSEOAnalysis addresses the technical quality phase.
Content brief and team workflowSemji includes an AI-assisted content brief generator that creates structured writing briefs from keyword and competitor analysis: recommended heading structure (H1/H2/H3 targets), semantic terms to include, questions to address, word count targets, and links to reference content. Teams can collaborate on briefs and drafts within the platform. CMS integration allows writers to optimise directly in WordPress, HubSpot, or Drupal with the Semji scoring sidebar. This editorial workflow integration positions Semji as a content team tool rather than just an SEO analyst tool.No content brief generation or editorial workflow integration. DeepSEOAnalysis is a technical audit tool — it validates the implementation quality of published pages rather than guiding the content production process. For content teams needing integrated brief creation, writing optimisation, and editorial approval workflows, Semji addresses this; DeepSEOAnalysis validates the technical quality of the finished published pages.
Structured data and schemaSemji does not include structured data auditing as a core feature. The platform focuses on content semantic quality (are the right topics covered?) rather than technical structured data implementation (is the JSON-LD correctly formed and server-rendered?). Some content optimisation recommendations may include suggestions to add FAQ sections (which benefit from FAQPage schema) but the schema implementation itself is outside Semji's scope.Property-level JSON-LD validation with server-rendering detection on every audited URL. Checks whether structured data is in the initial server-rendered HTML vs only available after JavaScript execution. For pages that Semji has optimised to a high Content Score, DeepSEOAnalysis confirms the technical implementation matches the content quality — server-rendered Article, FAQPage, or HowTo schema that Google's HTML parser processes without JavaScript execution.
Core Web Vitals and performanceSemji does not measure Core Web Vitals or page performance. The platform tracks content score changes correlated with ranking outcomes but does not include page experience assessment. CWV and performance are outside Semji's content-focused scope.Real CrUX field data at p75 from Chrome users for every audited URL: LCP, CLS, and INP status. For content pages that Semji has optimised, Good CWV ensures the Page Experience ranking signal complements the content quality signal — both must be in place for maximum ranking performance.
Performance tracking and content attributionSemji includes a performance tracking layer that connects content scores with actual ranking and traffic outcomes — monitoring how Content Score changes correlate with ranking position changes over time. This attribution helps content teams demonstrate the ROI of content optimisation work. The platform also tracks which pages have been optimised and which still have low Content Scores, creating a prioritised content maintenance backlog.No content performance tracking or attribution. DeepSEOAnalysis provides per-URL technical quality snapshots — the technical implementation validation, not the content performance measurement. For tracking how content optimisations correlate with ranking improvements, Semji's built-in performance tracking or a rank tracker (AccuRanker, STAT, SERPWatcher) addresses this.
AI visibility and GEO scoringSemji does not include AI visibility scoring, GEO signal assessment, llms.txt support, or AI crawler access checking. The platform's content optimisation is focused on traditional organic search ranking signals — semantic completeness and topic coverage — rather than the AI search visibility framework.Five-signal AI visibility scoring: AI crawler access in robots.txt (GPTBot, ClaudeBot, PerplexityBot), llms.txt presence, FAQPage/HowTo JSON-LD server-rendering, question-heading ratio ≥20%, content chunkability ≤400 words average. Content optimised to a high Semji Content Score benefits additionally from AI visibility optimisation — ensuring the semantically rich content can be cited by AI search systems.
Pricing and access modelSemji pricing is enterprise/team-oriented and available by quote — the platform is positioned for content teams at mid-market and enterprise companies rather than individual SEO practitioners. Trial access is available; pricing depends on team size and content volume requirements.Anonymous full technical audit: $0, no signup, no email gate — the complete report at no cost. Free account: saved reports and one monitored site. Pro is $24/mo for five monitored sites; Agency is $89/mo for 25 sites and white-label workflows.

What each product is

What makes these two tools different?

Semji

Semji is best understood as a suite.

Semji provides NLP-based Content Score comparing pages against top-ranking competitors, AI-assisted content brief generation, real-time optimisation scoring in the editor, CMS integration for WordPress/HubSpot/Drupal, team collaboration on briefs and drafts, and performance tracking connecting content scores to ranking outcomes.

DeepSEOAnalysis

DeepSEOAnalysis is an ungated audit.

DeepSEOAnalysis audits individual pages for technical SEO quality: property-level JSON-LD validation (including server-rendering detection), real CrUX p75 from Chrome users, five-signal AI visibility scoring, canonical verification, and broken external link detection — free with no signup required.

When to choose which

Pick the tool that matches the job.

Choose Semji when…

  • You need to optimise content semantic depth — identifying which topics, entities, and questions top-ranking pages cover that your page doesn't.
  • You need a team content workflow with brief generation, collaborative drafting, and editorial approval integrated with your CMS.
  • You need to track how Content Score changes correlate with actual ranking and traffic outcomes to demonstrate content ROI.
  • You need CMS-integrated content optimisation — editing in WordPress or HubSpot with real-time Semji scoring in a sidebar.
  • You manage a high-volume content team producing SEO content at scale and need a systematic brief and scoring workflow.

Choose DeepSEOAnalysis when…

  • You need to validate that structured data on Semji-optimised pages is server-rendered (FAQ sections added during content optimisation benefit from FAQPage schema that must be in the initial HTML).
  • You need real CrUX p75 performance data — confirming content-heavy pages optimised with Semji also meet Core Web Vitals thresholds.
  • You need five-signal AI visibility scoring — confirming that Semji-optimised content is accessible to AI crawlers and has the right formatting for AI citation.
  • You need ungated per-URL technical audit without subscription — complete technical report for any URL, no signup required.
  • You need property-level JSON-LD validation with server-rendering detection — outside Semji's scope but necessary for rich result eligibility.

FAQ

Common questions

What is Semji used for?

Semji is used for AI-powered content SEO optimisation — helping content teams produce pages that cover the same semantic topics, entities, and questions as top-ranking competitors. Its primary users are SEO managers, content marketers, and editorial teams at mid-market and enterprise companies who produce a high volume of SEO content and need a systematic workflow for brief creation, content scoring, and performance tracking. Semji competes with Clearscope, Surfer SEO, and MarketMuse in the content optimisation platform category, with particular strength in team workflow features (brief management, CMS integration, collaborative editing) and performance attribution (connecting Content Score changes to ranking outcomes).

How does Semji differ from Surfer SEO and Clearscope?

Semji, Surfer SEO, and Clearscope all analyse top-ranking pages to produce content scoring and semantic optimisation recommendations. Key differences: Surfer SEO is most popular for its real-time SERP analysis and direct content editor integration; Clearscope is widely used for its clean grading system and simplicity; Semji differentiates through its team workflow features (collaborative briefs, editorial approval workflows, CMS integrations with WordPress, HubSpot, and Drupal) and its performance attribution layer (tracking how Content Score changes correlate with actual ranking outcomes). Semji is most suitable for content teams producing at scale with multiple writers and editorial oversight; Surfer SEO and Clearscope are more commonly used by individual SEO practitioners and small agencies.

Can I use Semji and DeepSEOAnalysis together?

Yes — they address sequential phases of the content SEO workflow. Semji optimises content depth and semantic coverage (ensuring pages cover the same topics as top-ranking competitors) — the content quality phase. DeepSEOAnalysis validates technical implementation quality (structured data server-rendering, CWV performance, AI visibility signals) — the technical quality phase. A combined workflow: use Semji to optimise content to a high Content Score before publishing, then audit the published page with DeepSEOAnalysis to confirm: FAQPage schema for any FAQ sections added during Semji optimisation is server-rendered; Article schema on the page correctly attributes authorship; CrUX p75 performance is Good; AI crawler access is enabled so Semji-optimised content can be cited by AI search systems.

Does content scoring replace technical SEO auditing?

No — content scoring (Semji, Clearscope, Surfer SEO) and technical SEO auditing (DeepSEOAnalysis) address different ranking factors. Content scoring optimises the semantic depth and topical coverage of page content — a relevance signal. Technical SEO auditing validates structured data implementation, page experience (CWV), crawlability, and AI visibility — technical quality signals. Both are necessary for full ranking optimisation: a page with excellent content depth but JavaScript-injected schema, Poor Core Web Vitals, and blocked AI crawlers leaves ranking potential on the table from the technical side. A page with perfect structured data and Good CWV but thin content that doesn't match user intent leaves ranking potential on the table from the content side.
