So the general view on satellite sites is that they're not worth it because of their low authority and the amount of link juice they provide.
However, I have an idea that is slightly different to the standard satellite site model. A client's website is in a particular niche, but a lot of websites that I have identified for potential links are not interested because they are a private commercial company. Many are only interested in linking to charities or simple resource pages. I created a resource section on the website, but many are still unwilling to link to it as it is still part of a commercial website. The website is performing well and is banging on the door of page one for some really competitive keywords. A few more links would make a massive difference.
One idea I have is to create a standalone resource website that links to our client's website. This would be easy to get links from sites that would flat out refuse to link to the main website. This would increase the authority of the resource and result in more link juice to the primary website.
Now I know that the link juice from this website will not be as good as getting links directly to the primary website, but would it still be a good idea? Or would my time be better spent trying to get a handful of links directly to the client's website? Alternatively, I could set up a sub-domain to set up the resource, but I'm not sure that this would be as successful.
