Lead Generation - Grading Leads via URLs

Hello!

I have some large lead lists from builtwith.com, and have been getting additional information for these leads via LinkedIn with a VA.

I am looking to more easily determine if these websites are worth reaching out to. Is there an easy way to determine if a website is valuable? I am thinking of a software that would check traffic, guess at revenue, etc.

Any Lead Gen masters out there that have dealt with large amounts of website date (100k+ website URLS) and been able to sift through and find the value?

Anything is helpful!!

On determining if a website is worth getting a link from or reaching out to, here's a few generalizations to consider (traffic and revenue is of course very important to consider too):
>Web design is not a hard requirement but it does say a lot by way of impressions regarding professionality and presentation which has it's own merit.
>Check the site's audience engagement
>Check the backlinks
>Check SEO visibility of the site
>Relevance

Detail's and specifics are the tricky bit but, like I mentioned, I think those points are good to consider.. Choose the best sites to leverage your online strategy and your all set. Good luck!
