Hi. I'm new in affiliate business and like to get some advice. Searched here in Amazon forum, but didn't find the answer. I'm working on Amazon blog - www.deals24.info and my main question is - is it better to have one large blog with many categories or many small blogs on sub domains, each for one category. Many small blogs I mean like digitalcameras.deal24.info, books.deals24.info ... - in this case the main blog will have like category tree linking to sub blogs. Also the same category tree will be on every other blog. All small blogs will have only home page text, other pages like 'About', 'Link Directory'... will link back to main blog 'About', 'Link Directory'... pages to avoid duplicate pages. No other text will be added. But all the products have reviews from Amazon. Main blog I'm thinking to keep product free and just add articles, lets say one (or more) article for each sub blog (for digitalcameras.deal24.info will be article about digital cameras and on the end of the article will be something like 'Check for deals' linking to digital cameras sub blog). I thinking to do the advertising (seo) only for main domain. This is what I have in my mind and I can't decide, which way to go. Any advice will be helpful. Thanks.
I'd definitely go with one large one that you can focus all the marketing efforts on. I used to have lots of small wordpress blog. Believe me when I say it's nightmares in management that just wastes lots of your time.
Be careful with the automated plugins - they will damage your search engine listings. Generally you either get duplicate content or poor quality content, both of which cause penalties from Google especially.
