I know the topic of 301 redirects is one that is highly debated. My site is an e-commerce business site that I plan on being long-term and I'm wondering how risky it will be to do 301 re-directs to it. The expired domains I will be using will be one's used in the exact same niche with all niche links. For example, some of them may be an expired site for a certain product I sell and then the 301 points directly to that specific product page on my site or they may be other e-commerce stores (same type as mine) that went out of business & in that case will re-direct to my homepage. I know that 301's are normally considered blackhat but I would assume doing it this way would not be risky for my site. I'd think that many times a big business would buy up other smaller sites/business and in that case need to 301 them to their site which would make it perfectly natural. If this case, I'd also think that it then wouldn't matter how many redirects you have to your main site (I've read many people say the more you have, the more "dangerous" it). I'd love for someone who has extensive knowledge or previous experience with this to share their opinion & shed some light. I would like to do this but certainly don't need to if it's going to be risky for my site.
