I own a website marketplace script bought online and it does not have a website access verification. I want to copy what Google Webmaster Tools and Website Broker are doing: to create a random string and upload it or copy/paste a meta code in the header to let my registered users verify site access/ownership after listing submission. I also want to add a domain who-is information check/pagerank/alexa rank/backlinks checker per listing in each user account when they submit a website/domain for sale just like what flippa is offering.
The script is open source and can be edited. Lastly, I want to edit the site SEO and make it SEO friendly by making each listing url appear with the title of the listing instead of showing the listing number.
Just to reiterate:
3 tasks/goals:
1. Website Access/Ownership Verification per listing that will be submitted per user account
2. Who-Is Info/Pagerank/Alexa Rank/Backlinks Checker per listing submitted
3. SEO friendly listing titles
