For years I have resisted interlink between my sites each which have a different topic under the same general category.
For example, one site sells basketball shirts, another sells baseball shirts, another sells football shirts.
Each site only mentions the word of its respective sport.
Yet each site uses the same general layout, coding, and very similar text other than the different sports words.
If I had it to do over again 7 years ago I would have just made 1 site. But it's too late for that...
1) Is it ok for me to put a left menu bar link on each site that links to the other sites using "basketball shirts" & "baseball shirts" in the link text on the football site, and visa versa for the other sites?
2) Is it okay to create a page that says "Sports shirts" on each site that links to the others using the link text mentioned above (but in paragraphs rather than left menu bar) or will that page have too much of the same text since each site will now have a page that says "sports shirts"?
Should I just pick the best site to go with option 2 on, assuming it's even okay to do option 1?
Thanks so much for your opinion.
