Welcome to the Q&A Forum

Domain authority is the key here, now only their links get crawled but they all get ranked, usually in the top 10.

So, there are lots of 'ifs' here, but the primary problem I see with your plan is that the CDN will return the content to Googlebot without the request hitting your server so you won't have the option to serve different headers to Googlebot. Remember that every page is the main HTML content (which may be static or dynamically generated for every request), and then a whole bunch of other resources (Javascript and CSS files, images, font files etc.). These other resources are typically static and lend themselves far better to being cached. Are your pages static or dynamic? If they are dynamic then you are possibly not benefitting from them being cached anyway, so you could use the 'vary' header on just these pages, and not on any static resources. This would ensure your static resources are cached by your CDN and give you a lot of the benefit of the CDN, and only the dynamic HTML content is served directly from the server. If most of your pages are static you could still use this approach, but just without the full benefit of the CDN, which sucks. Some of the CDNs are already working on this (see http://www.computerworld.com/s/article/9225343/Akamai_eyes_acceleration_boost_for_mobile_content and http://orcaman.blogspot.co.uk/2013/08/cdn-caching-problems-vary-user-agent.html) to try and find better solutions. I hope some of this helps!

As Marc has pointed out, you can't choose them, you can only increase your chances of having them appear by having the correct markup and appearing higher in search results. One other thing to note is that you can demote a sitelink in Webmaster Tools under the "Search Appearance" tab. For each search result page, you can demote specific pages you wouldn't want to appear as a sitelink. But I would absolutely recommend having Schema markup to have full descriptive sitelinks for search results, especially your branded ones. More real estate you can have in search the better

Hi Keri, Still testing, though i see no reason why this shouldn't work so will close the QA ticket. cheers!

Your web server logs keep track of every file that is serves and to whom it provides the data. The raw log files are difficult to read unless you are used to viewing that type of code. The process varies based on your server type. Ask your web host or developer for guidance.

From an SE point of view XML sitemaps are enough, if you have a large site you may want to consider having more than one sitemap for different categories. As Kieron suggested HTML Sitemaps are useful for people to navigate your site it might be worthwhile writing some PHP to convert the XML into HTML and making your HTML Sitemap a little more dynamic?
