I have a Magento webshop wich sells certain niche products. The market is small but growing. Te competition is hard, but we are rising in google rankings. We have a 2 man team to do things. We want to keep things white hat, cause we can't affort to get banned from Google or things like that. Our biggest competitor has announced he will start a forum. He has allready a lot of users that react on his blog. Do we have to fear this development? We also blog, but because we are fairly new we don't have a community yet. Only a few users react to our posts, but we see improvement. The blogs do get read a lot. Do you guys have tips to become an autority site for Google? We can't do everything, so we want to choose a few things, and do these good. On site SEO is allready fairly good.
