I run different sites on same server and IP. The topics of all sites are almost different. My 3 major sites are offering discount coupons, and 2 articles directories, 1 classifieds site. Supporting sites are funny sms, funny jokes and some other sites on different topics and they have visitors from India and Pakistan and found at google.com.pk and also from google.com Currently they are interlinked as follows: Links of coupons sites are present on all pages of articles directories and http://www.realclassifiedads.com and other supporting sites. links of articles directories are present at all supporting sites. classified ads site's links are present at directories and supporting sites. Now I want to know that will this interlinking considered to be a spam linking strategy? I have searched over the internet and forums but could not found any related topic. If any interlinking guru can let me know the best interlinking within my domains, I will be thankful. Should I get dedicated IPs for individual domains or interlink only one domain from any domain in list. If anyone has the same situation please share your linking strategy with me. Thanks and regards
I don't know about interlinking, but you should be doing a lot of internal linking within the individual sites in order to help your SERPS and to pass the ink juice throughout your site.
