Welcome to the Q&A Forum

Hi everyone, I'm a recent(ish) beginner to SEO, and while I feel I've got a good grounding in the industry now, there are still certain aspects that make me say "what!?". I'm looking to write a blog post on this and would love to know what parts of SEO still confuse you or make you say "what!?", and explain them from a semi-beginners point of view. Any comments appreciated! Thanks!

Hi, Just wondering if anyone has had this problem before. I'm just checking a client's GWT and I'm looking at their robots.txt file. In GWT, it's saying that it's all fine and returns a 200 code, but when I manually visit (or click the link in GWT) the page, it gives me a 404 error. As far as I can tell, the client has made no changes to the robots.txt recently, and we definitely haven't either. Has anyone had this problem before? Thanks!

If a large site has multiple regions (Australia, USA, UK, France), how will IP filtering to a particular area affect SEO. e.g: Ilive in the UK an if I visit the said website I would automatically be redirected to the UK subfolder of the site whereas somebody searching in Australia would be redirected to the AUS folder. Will there be any detrimental affect on SEO and will the search engines still be able to crawl the entire site no matter which data centre is being used?

A client is pulling content through an iFrame, and when searching for a snippet of that exact content the page that is pulling the data is being indexed and not the iFrame page. Seen this before?
