Hrefmatch is the first backlink exchange network designed natively for AI content workflows. As AI tools like Claude, ChatGPT, Cursor, and n8n accelerate content production, manual link-building outreach has become the bottleneck. Hrefmatch eliminates it entirely. Instead of cold emails, agency fees, and spreadsheets, Hrefmatch connects directly into your AI writing pipeline via an MCP (Model Context Protocol) server. While your agent writes, it automatically discovers relevant partner sites, places contextual links, and earns backlink credits - all within the same workflow, with no separate manual step. How it works: Connect your site to the network with two lines of code. When your AI agent publishes content that includes qualifying partner placements, you earn credits automatically. Those credits are then converted into inbound backlinks from niche-matched, quality-vetted partner domains - placed contextually inside their published articles, not in footers or sidebars. What sets Hrefmatch apart: Quality-first vetting: Every site in the network is individually reviewed. No PBNs, no link farms. Minimum thresholds for domain authority, real organic traffic, and content quality are enforced on entry. AI-powered topical matching: Partners are matched by niche, language, audience overlap, and authority signals - not just DR scores. Your backlinks come from sites your readers would actually visit. A-B-C link architecture: Built to avoid obvious reciprocal patterns, reducing footprint and keeping placements policy-aware and editorially natural. Full dashboard: Track DR history, monitor every live placement, and manage all your domains from a single interface. Hrefmatch supports major industries: SaaS, e-commerce, finance, health, legal, travel, education, and more - across all major language markets. It's built for publishers who scale content with AI and need their link-building to keep pace.

Agent Ready helps teams make their websites discoverable and usable by AI agents, crawlers, and LLMs. Paste any public URL and Agent Ready returns a 0–100 readiness score plus a plain-English fix for every issue it finds - so you can ship changes and re-scan in minutes. As AI assistants and autonomous agents become a primary way people find products and information, sites optimized only for human visitors get left behind. Agent Ready tells you exactly where you stand and what to fix. It audits your site against the standards that govern the agentic web: • Vercel Agent Readability Spec - semantic HTML, metadata, structured data, content clarity • llmstxt.org - llms.txt and llms-full.txt discovery files • Agent-protocol manifests — MCP server cards, A2A, agents.json, agent-permissions.json, NLWeb, x402, and more Results are grouped into Site, Page, llms.txt, and Protocol checks, each with a clear pass/fail and remediation step. A corpus benchmark shows how your site ranks against every other site scanned. Use it however you work: web app, REST API, MCP server (Claude Desktop, Cursor, Cline, Goose, Continue), CLI, client SDKs (npm + PyPI), and a browser extension for Chrome, Edge, and Firefox. Built for developers, technical founders, and DevRel teams preparing for AI search and autonomous agents. Free to scan - no signup or API key required.

IndexMyURL is indexing infrastructure for SEOs, agencies, and developers managing URLs they don't directly control — client backlinks, guest posts, directory listings, and other third-party content they want Google to discover faster. The problem is structural, not hypothetical. Once a URL sits outside your own verified Search Console properties, there's no reliable, direct way to tell Google "this URL exists." Most of the standard notification methods are either deprecated or restricted to narrow use cases, which is exactly why so many "instant indexing" tools fail to deliver anything beyond a sales page. IndexMyURL takes a different approach: every submitted URL receives crawl signals through multiple channels running in parallel, instead of relying on a single method that may or may not work. Coverage extends beyond Google — one of the channels also reaches Bing directly, which matters because AI search tools like ChatGPT and Copilot draw on Bing's index, so the same signal that helps Google discovery also feeds AI search visibility. Before any credit is spent, every URL goes through an automatic pre-check: invalid links, redirects, dead pages (404/410), and already-indexed URLs are filtered out and never charged. Once a campaign starts, each URL runs through its own tracked pipeline — queued, submitted, delivered, bot visited — with exact timestamps, visible in real time on the dashboard. Verification runs in parallel across both Google and Bing, checked at scheduled intervals over a 15-day cycle. If Google hasn't indexed a submitted URL by day 15, the credit is refunded automatically — no support ticket, no waiting, no manual request. Credits never expire and can be reused immediately. Campaigns support up to 10,000 URLs at once, added by direct paste, CSV upload, sitemap URL, or RSS feed URL. Users can choose a drip mode, with signals distributed gradually over 15 days, or an instant mode for faster, concentrated delivery.

GeoVector is an AI search visibility intelligence platform that helps businesses track, analyze, and optimize how they appear across AI-powered search engines like ChatGPT, Claude, and Google Gemini.
