We are an adventure travel tour company, who run hiking, kayaking, biking adventures in several countries. We have a travel tour operator website with a blog in a sub folder of the site. We want to add a section/category in the blog itself with a hiking club mini directory, that lists all hiking clubs in 1 or 2 specific countries.
The reason we want to do this is because the people searching online for these clubs are our target market and potential clients. We hope to rank for some of these searches, and encourage interest in our blog/website in the process. We also want the potential to build relationships with these clubs.
The question I want to ask is: if we add say 100 to 200 listings, and make all outgoing links no follow, will this harm our page authority, reputation with SE's or pose any other risk for our site. The other question is, do you think that this will dilute the context of our content - as its slightly different in context to the rest of our site content.
Are we better to set up a separate site for this purpose.
