I built up a good number of sites (around 80 odd) and many were interlinked with sitewide footer links. Recently my rankings for the keywords in these sitewides have dropped drastically in the serps Should i just remove them all and replace them with homepage only links? Its weird as i see my competition are still doing exactly what i am with worse backlinks. I didn't want to touch the sitewides as i was doing so well until recently. They are all in the same general niche.
