There are some products that are sold seasonally, some even for a very short period of time.
People who sell snow shovels normally sell it only for a few months. People who sell school supplies normally see spikes just before the schools open. Even with religious products, before holidays you see spikes in sales for different products. This kind of reminds me of when I went Sukkah shopping for a Jewish holiday. Anyway...
The question one SEO has in a WebmasterWorld is should you be doing link building differently for seasonal web sites. Sites that sell only that specific product at a specific time period.
Martinibuster, a leading link building expert, replied to this SEO saying, "I don't think that seasons play a role in enough niches where something like that might be part of the algorithm. I've acquired high quality relevant links out of season with no problems. It wouldn't surprise me if someone else posted that their experience is different."
Hoople, someone who has experience with seasonal sites, chimed in as well and laid out his complete strategy for building up seasonal web sites. You can check it out in the thread.
This is a good question. Would Google suspect that links would increase to seasonal sites around the time or before the time of that season? If links do not increase or increase on off-peak times, would that look bad. Some say no.
