What is AgentSEO?

AgentSEO gives teams and AI agents a way to work with SEO research and search visibility data through a developer-friendly API. It is designed for marketers, SEO practitioners, agencies, and developers who want to bring search research into their own applications and workflows instead of switching between separate tools for each task.

The product provides a REST API, a hosted Model Context Protocol (MCP) server, and client libraries for Node.js and Python. These interfaces let a developer or connected AI assistant request supported SEO data from a project or automation. AgentSEO focuses on practical research workflows such as keyword research, search engine results page (SERP) analysis, competitor research, rank tracking, content gap discovery, and visibility checks for AI-powered search experiences.

A team can use the API to gather search results for a topic, compare competing pages, find keyword opportunities, or connect ranking and visibility data to an internal dashboard. An agency can use it as a data layer within its own reporting or research process. Developers can connect the service to scripts, applications, and AI-agent workflows using the interface that fits their environment. The MCP server is intended for compatible AI clients, while the REST API and SDKs support direct integration from software.

AgentSEO is built for people who need structured search data that can be reused across workflows. Rather than presenting SEO as only a manual dashboard activity, it makes research capabilities available to software and agents through documented interfaces. Users should choose the relevant operation for their needs and review the returned data as part of their own analysis; search visibility changes over time and no tool can guarantee a specific ranking or business result.

AgentSEO offers a free entry tier alongside paid plans. Current plan limits and prices are listed on the official pricing page at agentseo.dev/pricing. Developers can review the documentation for API access, MCP setup, and SDK usage before integrating. Visit agentseo.dev to explore the product and documentation.

What is Unfair Links?

Unfair Links is a premier local-entity SEO link building platform designed to help local businesses, agencies, and SaaS brands secure matched backlinks on real, verified Google Business Profile businesses. Instead of relying on spammy private blog networks (PBNs), automated directory submissions, or irrelevant guest posts, Unfair Links connects you directly with legitimate local entities operating in your target market, language, and category.

Traditional link building often suffers from a severe lack of quality control. Marketers frequently pay premium rates for backlinks placed on artificial domains that have no genuine physical footprint or real-world audience. Unfair Links solves this problem by rooting every placement in verified local entities. When search engines evaluate local authority and proximity signals, contextual references and links from actual local businesses provide unbeatable authority and thematic relevance.

Key features and benefits of Unfair Links:
- Genuine Google Business Profile Entities: Backlinks and brand mentions are placed on authentic business sites tied to active, verified Google Business Profiles.
- Exact Relevance Matching: Ensure your links come from the exact geographic territory, business category, and language that matches your audience.
- Complete Pre-Purchase Transparency: Review trust scores, organic performance, domain signals, and placement criteria prior to placing an order.
- Sustainable Local SEO Authority: Build an authentic backlink profile that withstands search engine quality updates and reinforces local map pack rankings.
- Streamlined Agency Workflow: Ideal for digital marketing agencies, SEO consultants, and enterprise brands managing multi-location local search strategies.

Empower your business with high-impact, authentic local authority that drives real customer discovery and sustainable search rankings.

Why Local Entities Matter for Modern SEO:
Search engine algorithms have advanced beyond basic keyword density and backlink quantities. In modern search architecture, authority is established through entity verification, geographic relevance, and demonstrable real-world credibility. When a business references your website, search engines interpret that connection as a genuine commercial recommendation rooted in a physical service radius. Unfair Links bridges this critical gap by vetting every single partner business for active Google Business Profile ownership, authentic customer reviews, localized NAP consistency (Name, Address, Phone), and clean indexing history before making it available in the network.

What problem it solves

Traditional link building relies on low-quality PBNs, fake blogs, and irrelevant guest posts that search engines discount. Unfair Links provides matched local-entity SEO links on verified Google Business Profile businesses in the right market, language, and trust score.
