Welcome to the Q&A Forum

In Umbraco you have total control over you html, meta tags, page names etc. so there's not anything that should cause you SEO issues. You may find this link interesting though, there are a few packages you can install to make life easier. http://blog.mattbrailsford.com/2010/07/15/10-essential-umbraco-packages-for-seo/

Thanks for the response! Yes the client is pretty web savvy so I'm sure they're asking all the right questions when it comes to metrics. However I'd still like to be able to give them something more concrete re link equity. To be clear this is placed/partnered content and not ads as such - more microsites within the root domain. What I can respond with so far DA is excellent, PA is very low for all options. One option also has very spammy links pointing to the example page provided None of the links in the examples are no follow however the content is marked as advertisement or sponsored content Cite JC Penny etc and risks and underline importance of sustainable linkbuilding Any other thoughts anyone?
