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 Testimonial.to?

Testimonial.to is a tool for collecting and displaying text and video testimonials, making it easy to turn happy customers into powerful social proof. Gathering testimonials is usually a manual, awkward process, but Testimonial.to streamlines it: you share a simple link, customers record a video or write a text testimonial, and everything is collected in one place. You can then display them on your website with embeddable widgets and walls of love, so the trust and credibility your customers provide actually shows up where it can influence buyers.

Its strengths are effortless collection — including video — and easy display. By giving customers a frictionless way to submit testimonials via a link, it removes the biggest barrier to gathering social proof, and its support for video testimonials adds an especially persuasive, authentic format. Once collected, the testimonials can be embedded across your site in attractive formats designed to boost conversions. Since social proof is one of the most effective ways to build trust and close sales, having a simple system to gather and showcase it can meaningfully improve how persuasive your website and marketing are.

Testimonial.to is a great fit for startups, SaaS companies, course creators, freelancers and small businesses who want to collect testimonials — especially video — and display them to build trust and increase conversions. It sits alongside tools like Senja in the social-proof space, distinguished by its simple link-based collection and strong video support. If you have satisfied customers but no easy way to capture and show off their praise, Testimonial.to gives you a straightforward, effective way to turn that goodwill into a conversion-boosting asset across your site.
