I have a site which traditionally gets most of it's links in one month of the year due to the seasonality of the product focus. The site has a large, old, 100% natural link graph. There has never been a link overtly acquired for the site.
Does anyone have experience with the effects of building links outside of the traditional season? If Google is ignoring the SERPs for the main keyword right now as the query does not deserve freshness do they also ignore new links? How conservative do I need to be in building links "out of season" to get the jump on the competition during season. It's tough to plan link building or hire link builders if all the link building needs to be concentrated into a maximum of two months of the year.
Any help is appreciated and thanks in advance.
