Is it beneficial to have multiple links and multiple articles from the same website. Or is it worth the investment in content creation if one link / article has already been obtained? Wonder if anyone can offer any feedback on this.
According to me, you can still go ahead and obtain multiple links from the same site. That should not be a problem. But, I would suggest you to make sure that the pages (from which you obtain the links) are indexed by google and also try to use different keywords and use links to different landing pages. This way it gives you a diversity in link building which is good. Show variety in Anchor text, landing pages and backlink sites This should help you
Yes I thought the same, I was just unsure how much weight would be placed on the secondary links as opposed to the initial link you already have. Even with different keywords used and would money be better spent in different departments (gaining links elsewhere) when operating on a limited budget.
I agree with @kingofking suggestion, also make sure to make time gaps in between your links, do just keep adding links every few days. These multiple links from same website can also help your ranking on Technorati if your website is more on content rather on product sale.
