OK so i'm running a small campaign on one of my sites. I struggled initially to get a lot of the links indexed but the majority are coming along now but the ones that seem to be showing up most in ahrefs at least are my main keywords. One keyword being 26% where as my URL is only 16%. I don't want to run the risk of getting penalised so what would you suggest I do at this moment in time? Would a few wikis or bookmarks help or would I run the risk even higher of getting penalised for using spamming links?
