# Anchorflow

> Anchorflow is an AI-powered internal linking engine designed to connect content clusters, eliminate orphan pages, and generate natural, contextual anchor text suggestions using Google Gemini LLMs to improve Google rankings and topical authority.

## Product Overview

Anchorflow solves one of the most tedious and high-leverage SEO challenges: building an optimal internal linking structure. Unlike traditional WordPress plugins that force exact-match keywords indiscriminately, Anchorflow understands the semantic intent of every article, identifies exact sentences where links logically belong, and ensures links reinforce topical clusters without keyword cannibalization.

## Core Capabilities

- **Deep Sitemap Crawling**: Crawls standard XML sitemaps, sitemap indexes, and multi-sitemap SILO structures with configurable crawl depth, delay throttling, and URL exclusion patterns.
- **AI Keyword & Intent Extraction**: Leverages Google Gemini LLM to identify the primary keyword, search intent, and secondary topic clusters for every indexed page.
- **Contextual In-Paragraph Link Suggestions**: Locates natural sentences across your existing content where linking to target pages transfers maximum PageRank and topical relevance.
- **Orphan Page Detection**: Instantly identifies published URLs with zero or insufficient incoming internal links and prioritizes finding relevant context passages to link back to them.
- **Anti-Cannibalization Guardrails**: Enforces outbound link limits per page, prevents competing pages from targeting the same primary anchor, and enforces anchor text variety.
- **SILO Architecture Support**: Honors category and cluster boundaries to maintain thematic isolation across subdirectories and topic hubs.
- **Actionable Copy & Export**: View exact before/after sentence diffs, copy suggested HTML fragments with a single click, or export link suggestions as structured CSV for CMS import.

## How It Works

1. **Input Sitemap**: Submit your website's XML sitemap URL (e.g. `https://example.com/sitemap.xml`).
2. **Autonomous Crawl**: Anchorflow fetches page content, extracts clean article text, removes boilerplate, and analyzes existing outbound/inbound links.
3. **Semantic Analysis**: Gemini AI processes each page to determine semantic focus, target keywords, and topical entities.
4. **Graph Generation**: Anchorflow evaluates the internal link graph, calculating topical relevance between source and destination pages while filtering out existing links.
5. **Actionable Suggestions**: For each high-confidence opportunity, Anchorflow presents the source paragraph, the exact suggested anchor text, the destination URL, and a contextual preview.
