Thank you all for your answer, I agree with you that social is the way to go.
However, I was wondering if anyone had some advice in terms internal linking which I think will still be used as a signal in addition to external links.
Let's say I have 30 pages that talk about "watches" ( this is just an example ) and I have a homepage that is optimized for "watches" and that I want to rank on the keyword "watches".
Which anchor text would you use internally to link to the homepage from my 29 internal subpages ? I read that if I link 29 times with the keyword "watches" as anchor text I am penalized by google.
The issue I have is that whenI type ~watches in google to find synonyms for watches I only find 2 synonyms "heuer" for and "rolex" ( which is not a lot variety for 29 pages ). Let's say I don't sell any of those brands... it means than other than linking with the keyword "watches" internally I have no other choice... even though I know i will get penalized.
Did I get that right or I am missing something ?
