I'm building an SEOTesting clone

A developer and SEO specialist is building an open-source clone of SEOTesting, a paid tool for tracking search engine optimization performance. The project will use LLMs like Claude to architect a web app that connects to Google Search Console and displays basic metrics such as clicks, impressions, CTR, and position. The developer aims to eventually add testing functionality and historical data storage beyond Google's 16-month window.

I've decided I'm going to embark on an ambitious project, and I'm going to do it in public. This is my first post outlining my plans.

I am an organic search specialist (SEO). I have spent much of my professional career learning how search engines work so I can optimize websites to rank better. This involves many different tools, most of them paid. One of my favorite paid tools is SEOTesting.

At my day job, I recently lost access to this tool. I was disappointed because there is nothing else readily available that complies with our strict corporate compliance requirements.

Since LLMs have flattened the learning curve for building complex projects, I figured I'd leverage Claude to help me architect an SEOTesting clone.

For those unfamiliar, SEOTesting is a web app which connects to Google Search Console. It allows you to create tests to track performance before and after implementing optimizations. You can also create content groups to permanently segment your traffic into logical site sections based on URL rules you set. It also houses your historical GSC data so you can see trends far beyond the 16-month window Google offers you. The MVP is going to be dead simple (a naïve statement, I'm sure). I just want to be able to connect to Google Search Console and display basic metrics--clicks, impressions, CTR, and position--in a dashboard view. Once that's working, I will get testing functionality and other quality-of-life improvements online.

Here's the rough sketch of the architecture stack I'm planning to build out:

As of now, that's all I have mapped out. Stay tuned for updates.
