Competing with bigger players

Hello everyone, Wondering if I could get some thoughts on a challenge we face with organic traffic.We`re a fashion and interior multi brand and a lot of our brands are small and do not have great search volume. Another challenge is that larger retailers who stock the same brands will have a high search rank.Thinking about the business as a whole or within specific brands (examples include Stussy and Mina Perhonen) how would you work around these limitations?All thoughts and suggestions most welcomed!
