Welcome to the Q&A Forum

We carry a few brands that have special foreign characters, e.g., Kühl, Lolë, but do search engines recognize special unicode characters? Obviously we would want to spend more energy optimizing keywords that potential customers can type with a keyboard, but is it worthwhile to throw in some encoded keywords and anchor text for people that copy-paste these words into a search? Do search engines typically equate special characters to their closest English equivalent, or are "Kuhl", "Kühl" and "Kühl" three entirely different terms?

We are developing our mobile site right now and we are using a user agent sniffer to figure out what kind of device the visitor is using. Once the server knows whether it is a desktop or mobile browser it will deliver the appropriate template. We decided to use the same URL for both versions of the page rather than using m.websiteurl.com or www.websiteurl.mobi so that traffic to either version of these pages would register as a visit to the page. Will search engines consider this cloaking or is mobile "versioning" an acceptable practice? The pages in essence are the same, the mobile version will just leave out extraneous scripts and unnecessary resources to better display on a mobile device.

My site has faceted navigation that allows shoppers to filter category page results by things brand, size, price range, etc.  These pages 302 redirect to the same page they came from, which already include canonical meta tags.  I added the rel="nofollow" attribute to the facet links and added the line "Disallow: /category_filter/" to robots.txt. One of our SEO consultants told me that this is likely diluting the potency of the page's link juice since they are divided among all the page's links, including the links I am instructing crawlers to disregard. Can anybody tell me whether I am following the best practices for links that redirect to the same page?

HTML5 is supposed to revolutionize the way browsers, web clients and services are supposed to "understand" information on the web. I have been planning on converting my site to HTML5 ever since it went into a working draft last spring, however I wanted to know if upgrading to HTML5 would offer any SEO benefits or if it would actually have a negative effect on how my site is perceived on the web. I guess my real question here is "Do search engines recognize HTML5 sectioning?" Is content found in semantic sections like <header>, <footer>, <nav>, <aside>, treated any different than content inside generic HTML4 containers like, or ? </aside> </nav> </footer> </header>
