Hope you are doing well. Actually I'm working for a client who have more than 100 websites having different "domain.name" but logically and categorically they are same. He wants me to send links from these 100 domains to the original domain (business website/official). He has created a page which have two targeted keywords that reflects his nature of business. Further he has provided such free domain services to his client as value added service. He wants me to bring links from 100 websites to his professional business website. My question is that what best procedure google could admire if I do the following:
noindex, follow) >>> can give us benefit of many links pointing to official website, but it could be harm, if we use this meta just for getting links, (getting links in bulk in a short period could harm the website) what do you say about?
(index, nofollow) >>>> using this meta canít give us benefit, causing duplicate content issue.
(noinex, nofollow) >>>> this could only give us benefit of traffic.
I preferred to use (noindex, follow) meta to get the benefit of links pointing to his official website. What do you say about? any idea will be higly appreciated.
