Looking for a big website for my SEO tool

Hello SEO champs

I built a tool for semantic SEO, iam looking for a big website to try it on (1,000+ pages), i will do the work for free in exchange i would like to conduct a study on the website (before and after) and that study ll be published in public, in terms of data ill only need the charts from google search console (GSC)

Here is the details I built a tool to create structured data for nearly anything online which contains all types published on schema org, the tool not only can produce them but can also link them together

Example: in normal situation, if a page is about a product it usually has a product schema in addition to a local business schema, but that only gives limited amount of info to google knowledge graph, however with my tool it ll create a product, that is connected to a produt catalogue that contains all other products, which is connected to local business which is connected to all employees, GMB, contact us etc .. meaning all entities on yourbsite will be connected together The tool produce the structured data in JSON-LD, LD stands for linked data but no one does the linking so far, moreover, the product page usually contains other products, reviews, forms and that doesnt show in normal schemas and thus they ll be left undcoumented, with my tool you can document all of them

The tool can do more things and its not online yet, coz it still needs some design and make up, but all the functionality is working so before i start any work i will demonstrate everything iam going to do for the owner of the website, including the tool, how it works ill also show them my track records, and my website etc. For anyone to make sure that iam legit, in exchange i need a proof they are the owner of the website and a signed paper that allows me to publish data from GSC

Once the work is done, ill make a public study for the website before and after to demonstate the results , ill share the study for everyone to learn

Ecommerce website, would be a perfect fit, bloggers, tech, specific niches .. can do also

Thanks for reading
