Project Purpose

The purpose of the Content Density and Semantic Weight Analyzer is to provide SEO professionals and content teams with a precise, actionable evaluation of web page content at the section level. In modern SEO, not all page sections contribute equally to search visibility, user engagement, or informational clarity. This project addresses that challenge by quantifying the semantic strength and relevance of each section relative to targeted queries and overall page content.

Specifically, this project aims to:

• Assess Content Quality at Granular Level: By analyzing each section separately, it identifies which parts of a page carry the most meaningful information, allowing clients to focus on high-impact content rather than treating the page as a single monolithic unit.
• Align Content with SEO Objectives: The analyzer measures the semantic relevance of sections against strategic SEO queries. This ensures that content is not only dense but also targeted, helping pages rank effectively for the intended search terms.
• Optimize Content Distribution and Balance: Pages often suffer from uneven content distribution, where some sections dominate the informational load while others provide minimal value. The project calculates dominance and content balance metrics to highlight such disparities.
• Detect Redundancy and Improve Efficiency: Redundant or overlapping content can dilute page value and confuse search engines. By identifying high-redundancy sections, clients can streamline content, reducing repetition while maintaining or improving informational coverage.
• Support Data-Driven Decision Making: The generated insights empower SEO strategists to make informed decisions regarding content revision, expansion, or removal, ensuring that every page section contributes effectively to both user experience and search engine visibility.

In essence, the project equips clients with an in-depth, quantifiable understanding of page content, transforming subjective content assessment into measurable, actionable insights that improve SEO performance and user engagement.

Project’s Key Topics Explanation and Understanding

The Content Density and Semantic Weight Analyzer project is grounded in several core concepts that collectively define how the quality, relevance, and impact of web page sections are measured. Understanding these topics is essential for appreciating the methodology and outputs of the project.

Content Density

Content density refers to the concentration of meaningful information within a section of a web page relative to its length. High-density sections convey more relevant information per unit of text, making them more impactful for both users and search engines. Measuring content density allows SEO professionals to identify underperforming sections, overstuffed content, and areas where information could be enriched.

Key points:

• Focuses on semantic content rather than just word count.
• Helps detect sections that may appear substantial but provide limited informational value.
• Supports balanced content distribution across the page, preventing dominance by a few sections.

Semantic Weight

Semantic weight quantifies the informational importance of a section based on its contribution to the overall meaning of the page and its alignment with strategic queries. Unlike content density, which measures concentration, semantic weight emphasizes the significance of the content in context.

Key points:

• Incorporates both the section’s length and its relevance to target topics.
• Helps prioritize sections that carry the most actionable information for SEO performance.
• Assists in identifying key sections that should be highlighted or optimized for search engines.

Section-Level Analysis

Unlike page-level metrics, which treat content as a single block, section-level analysis examines each subsection independently. This approach provides a granular understanding of which parts of the page drive the most value.

Key points:

• Enables precise optimization and targeted content revisions.
• Facilitates strategic allocation of effort in content creation and improvement.
• Supports detailed reporting to clients on actionable insights.

Query Relevance and Semantic Alignment

Each section is evaluated against a set of predefined queries relevant to the client’s SEO goals. This semantic alignment ensures that content not only carries information but also addresses the specific topics and questions users are searching for.

Key points:

• Uses embedding-based similarity metrics to quantify relevance.
• Helps identify high-performing content that is likely to rank well for targeted queries.
• Highlights content gaps where new sections or modifications are needed.

Redundancy Detection

Redundant content reduces page efficiency and may negatively affect SEO. This project measures redundancy at the section level, identifying overlapping content within the page.

Key points:

• Assesses overlap between sections using semantic similarity scores.
• Labels sections as low, medium, or high redundancy to guide content refinement.
• Supports efficient page structuring and prevents dilution of high-value information.

Content Balance and Dominance

These metrics evaluate how evenly the semantic weight is distributed across the page. A page dominated by a single section may underutilize available space and miss opportunities for additional content optimization.

Key points:

• Dominance score: highlights sections disproportionately influencing the page.
• Content balance: measures the uniformity of informational contribution across all sections.
• Guides clients in achieving an even and effective spread of information.

Model Used: sentence-transformers/all-mpnet-base-v2

Overview of the Model

The project leverages the all-mpnet-base-v2 model from the Sentence-Transformers family, a high-performance transformer-based embedding model designed to convert textual content into dense numerical representations (embeddings). These embeddings capture semantic meaning at the sentence, paragraph, or block level, making them suitable for tasks such as semantic similarity, search relevance, clustering, and ranking. The model provides a balance between accuracy and efficiency, making it practical for real-world applications where multiple pages and queries are processed.

Core Architecture

all-mpnet-base-v2 is built upon MPNet (Masked and Permuted Pre-training for Language Understanding), an advanced transformer architecture combining the strengths of BERT and XLNet. Key characteristics include:

• Bidirectional Context: Unlike traditional autoregressive models, MPNet considers both left and right context simultaneously, improving the understanding of word relationships.
• Permutation Language Modeling: Instead of predicting masked tokens independently, MPNet uses permuted sequences during pretraining, allowing the model to learn richer dependencies.
• Sentence-Transformer Adaptation: Through the Sentence-Transformers framework, the base MPNet model is fine-tuned on large-scale semantic similarity datasets, ensuring that embeddings reflect meaningful semantic distances between texts rather than only token-level predictions.

How the Model Works

The model processes text in the following steps:

1. Tokenization: Input text is converted into a sequence of tokens using the model tokenizer, mapping words and subwords to numerical indices.
2. Contextual Encoding: Tokens are passed through multiple transformer layers, producing contextual embeddings for each token that reflect both local and global semantic relationships.
3. Pooling: Token embeddings are aggregated (typically via mean pooling) to produce a fixed-length vector representing the entire input text.
4. Embedding Output: The resulting dense vector captures semantic content and can be compared with other vectors using similarity metrics such as cosine similarity.

This pipeline allows sections of web pages and query texts to be represented in the same embedding space, enabling effective semantic matching.

Role in the Project

In this project, the model serves as the foundation for semantic analysis of page sections:

• Section Embeddings: Converts each processed block of content into a dense vector for similarity comparison.
• Page-Level Embeddings: Aggregates section embeddings to provide an overall representation of a page’s informational content.
• Query Matching: Embeddings of client-provided queries are compared with section embeddings to determine relevance and alignment.
• Semantic Weight and Density: Embedding-based similarity scores are combined with section size to compute meaningful metrics for ranking and labeling content.

The use of this model ensures that the evaluation is context-aware and semantically grounded, rather than relying on keyword presence alone.

Benefits for SEO and Content Analysis

Implementing all-mpnet-base-v2 in the project provides several practical benefits:

• Accurate Semantic Matching: Sections are scored based on meaning, not just keyword overlap, allowing identification of content that truly aligns with user intent.
• Cross-Section Comparisons: Enables detection of redundant or overlapping content, improving page optimization.
• Content Prioritization: Sections with higher semantic weight and density can be highlighted, supporting SEO strategies that emphasize informative, high-value content.
• Actionable Insights: By quantifying semantic relevance for each query, the project provides actionable guidance on which page sections to optimize, restructure, or expand.

Overall, the model acts as a semantic lens that transforms raw text into actionable insights, driving informed SEO decisions and content improvements.

Function chunk_by_tokens

Overview

This function splits a large block of text into smaller, token-based chunks using a Hugging Face tokenizer. The goal is to generate semantically coherent segments for embedding generation. The function supports adaptive overlapping between chunks, preserving context in longer text while avoiding unnecessary duplication in shorter text. This ensures accurate semantic representation when computing embeddings for content density and query relevance analysis.

Key Code Explanations

·         tokens = tokenizer.encode(text, add_special_tokens=False) – Converts the input text into tokens, ignoring special tokens to focus on content-relevant tokens.

·         overlap = 30 if len(tokens) > int(1.5 * max_tokens) else 0 – Automatically adds a 30-token overlap for long texts to maintain semantic continuity between consecutive chunks.

·         token_strs = tokenizer.convert_ids_to_tokens(chunk_tokens) & chunk_text = tokenizer.convert_tokens_to_string(token_strs).strip() – Converts token IDs back to readable strings while preserving the original content structure.

·         start += max_tokens – overlap if overlap else max_tokens – Ensures chunks move forward correctly with or without overlap, maintaining sequential coverage of the text.

This function is essential for breaking long sections into manageable pieces that can be embedded and analyzed without losing context, which is critical for accurate semantic weight and density measurement.

Function preprocess_page

Overview

preprocess_page prepares the extracted sections of a web page for analysis by performing multiple preprocessing steps. It merges text blocks within sections, filters out boilerplate or low-value content, and applies token-based chunking using the previously defined chunk_by_tokens function. Each resulting chunk is assigned a unique section ID and a token count, making the sections ready for embedding and semantic evaluation.

Key Code Explanations

·         merged_text = ” “.join(section.get(“blocks”, [])).strip() – Combines all paragraph-like blocks under a section into a single text string to maintain context.

·         if any(bp.lower() in merged_text.lower() for bp in boilerplate_terms): continue – Filters out common boilerplate phrases (like “read more” or “privacy policy”) to focus on high-value content.

·         chunks = chunk_by_tokens(merged_text, tokenizer, max_tokens, overlap) – Splits the merged section text into token-based chunks for embedding generation.

·         section_id = hashlib.md5(f”{url}_{section[‘heading’]}_{idx}”.encode()).hexdigest() – Generates a unique hash for each chunked section to track it across analysis stages.

·         if len(words) < min_word_count or chunk_tokens < min_word_count or chunk_tokens > max_token_length: continue – Ensures only meaningful chunks of appropriate length are retained for analysis.

This function guarantees that only informative, semantically meaningful sections proceed to the embedding stage, enhancing the quality of query relevance scoring and semantic density measurement.

·         page_embedding = torch.mean(torch.stack(embeddings), dim=0) – Stacks all section embeddings into a single tensor and calculates the mean along the first dimension, producing an averaged vector that represents the full page’s semantic content.

·         processed_page[“page_embedding”] = page_embedding – Stores the resulting page-level embedding within the page dictionary for downstream analysis, keeping the data structure unified and easily accessible.

This function is crucial because it allows page-level semantic comparisons, which complements section-level analysis and provides clients with a quantitative measure of a page’s overall informational strength.

Function compute_section_page_similarity

Overview

This function calculates the cosine similarity between each section and the overall page embedding. The similarity score quantifies how closely a section aligns with the semantic content of the entire page. Sections with higher similarity values represent the core or most representative content of the page, while lower values may indicate peripheral or less relevant content. This metric is valuable for identifying high-value sections and understanding content balance across a page.

Key Code Explanations

·         page_emb = processed_page.get(“page_embedding”, None) – Retrieves the page-level embedding computed previously. A missing embedding triggers an informative error, ensuring the workflow is followed correctly.

·         sec_emb = sec[“embedding”].unsqueeze(0) – Adds a batch dimension to the section embedding to make it compatible with the cos_sim function.

·         sim = util.cos_sim(sec_emb, page_emb).item() – Computes cosine similarity between the section and page embeddings, producing a scalar value indicating semantic alignment.

·         sec[“page_similarity”] = float(sim) – Stores the similarity score in the section dictionary, making it accessible for downstream analyses such as ranking or visualization.

By using this function, clients can highlight sections that best represent the page and make informed decisions about content optimization or summarization.

Function compute_section_query_similarity

Overview

This function calculates the cosine similarity between each section and a set of query embeddings, which represent search intents or user questions. Each section receives a score per query, quantifying its relevance to that query. This enables query-focused analysis of page content, helping clients identify which sections best satisfy user intent and improve targeted SEO performance.

Key Code Explanations

·         query_embeddings = model.encode(queries, convert_to_tensor=True, device=device) – Encodes all queries into embeddings compatible with the section embeddings. This allows vectorized similarity computations.

·         sec_emb = sec[“embedding”].unsqueeze(0) – Adds a batch dimension for compatibility with util.cos_sim.

·         sims = util.cos_sim(sec_emb, query_embeddings) – Computes cosine similarity between the section embedding and each query embedding, producing a vector of similarity scores.

·         sec[“query_scores”] = {queries[i]: float(sims[i]) for i in range(len(queries))} – Stores the similarity scores in a dictionary mapping queries to their relevance, making it easy to access for ranking, filtering, or reporting.

This function allows clients to directly evaluate content against multiple search queries, enabling prioritization of high-impact sections for SEO optimization or content refinement.

Function compute_semantic_weight_density

Overview

This function calculates semantic weight and semantic density for each section. These metrics quantify the informational strength of content in relation to the page and the queries:

• Semantic Weight measures the overall contribution of a section by combining its relevance to the page (page_similarity) and its relevance to queries (average of query_scores), scaled by the logarithm of the token count to account for section length.
• Semantic Density normalizes the weight by the number of tokens, indicating information density per token.

These metrics allow clients to identify sections that are both relevant and information-rich, enabling better SEO prioritization and content optimization.

Key Code Explanations

• token_count = sec.get(“token_count”, 1) – Ensures a fallback token count to prevent division by zero.
• mean_query_sim = np.mean(list(query_scores.values())) if query_scores else 0.0 – Computes the average query relevance per section.
• semantic_weight = (page_sim + mean_query_sim) * math.log1p(token_count) – Combines page and query relevance, scaled logarithmically by the section length, giving longer and relevant sections more weight.
• sec[“semantic_density”] = round(float(semantic_weight / token_count), 6) – Normalizes the weight per token, highlighting densely informative sections independent of length.

This calculation enables comparative assessment of sections across a page, helping clients focus on high-value content efficiently.

Function rank_and_label_sections

Overview

This function categorizes page sections into three value tiers — High, Medium, and Low — based on their semantic density (or another specified metric). Labeling sections in this way allows clients to quickly identify top-performing content and areas that may need improvement or optimization.

The classification is primarily percentile-based, ensuring that sections are labeled relative to other sections on the same page. If all sections have nearly identical density, the function falls back to ranking by semantic weight to still differentiate content importance.

Key Code Explanations

·         densities = np.array([s.get(density_key, 0.0) for s in sections], dtype=float) – Extracts all section density values to compute percentiles.

·         if np.allclose(densities, densities[0]): – Checks for uniform values across sections; triggers fallback logic.
