I am thinking of 3 options.
1. Put a 2 page site/email capture on it with an offer, and try and build a list from there.
2. Add lots of quality content and focus on a variety of keywords, add articles, syndicate them see where that leads.
3. Have the .index as the email capture, with an option to go to the main site. Then offer good information, with occasional links to recommended products. etc.
I have only ever focussed before on number 2. I have said this before here and found that ROI in terms of effort just was not there - to be fair I only used amazon products so maybe consider products with better return.
Very open to suggestions. If it can build a list without the need for the large information site behind it then it might be pointless building the site...but I might just be missing out on so much more that I have not even considered.
Any guidance or thoughts would be massively appreciated!
