Is DOCTYPE important for SEO?
-
Hello fellow Mozzers.
I am just having a brief look at a potential clients website before speaking to them tomorrow and whilst looking at the source I noticed that they don't appear to have a clear definition for their Doctype.
All the have at the top of each page is
I have to admit that Doctypes aren't my strong point but I know that they are normally slightly more descriptive than this.
Can this have any effect on rankings? or is this just an issue for W3C validation?
Thanks

If it is an HTML 5 page that should be just fine as it is the HTML 5 doctype tag.
Check out the info here: http://www.w3schools.com/html5/tag_doctype.asp
It might cause trouble with really old browsers, but if they have that going I would hope they have already thought about the reasons for and against using it
EDIT: even better link: http://www.w3.org/TR/html5-diff/#doctype

Does cache-control : private hurt SEO?
Hi, I recently found I can no longer view our web pages in Google's cache. I get 404 errors. http://webcache.googleusercontent.com/search?q=cache%3Ashop.nordstrom.com%2Fc%2Fwomens-shoes&rlz=1C1GGRV_enUS751US751&oq=cache%3Ashop.nordstrom.com%2Fc%2Fwomens-shoes&aqs=chrome..69i57j69i58.3575j0j4&sourceid=chrome&ie=UTF-8 I did a fetch and render in Search Console and found our header includes a "cache-control: private" entry. The 404's started happening recently. Would this response be the culprit? If Google cannot cache the website, is this bad for SEO? On the surface of it, it sounds bad.

SEO for multiple languages [Arabic]
Hello all, I am currently managing a Marketplace that comes in two different languages: English & Arabic. The English website is, fortunately, doing quite well in terms of SEO performances but, not the Arabic one. The website has two kinds of content: Static content: controlled by me. It includes menu items, navigation, static pages etc which is properly translated among the two languages User-uploaded content: It includes ads/news posted by the user which may not be translated to Arabic if they chose not to do it. Now if somebody goes to the Arabic website and check a news item that doesn't have an Arabic translation, it will show the English title. I am assuming, serving content in a different language that is specified in the hreflang is a straight no, right?

CDN for SEO (or not)?
Does CDN impact on SEO or not? There seems conflicting ideas as to whether they impact positively or negatively, I realise that if the page loads quicker this is a good thing for SEO and usability of course. Does Google see CDN as just cheating and a get-around for not doing the work from the ground up and using good hosting etc? Do you have any direct experience? All constructive input much appreciated!

Changing Servers + Effect on SEO
Hi, I am currently with a very slow server. Our website takes quite a while to load, FTP is very slow and content changes with Wordpress are slow because even the database connection takes a lot of time. However, my website ranks very well. Traffic has doubled in the last year. Our domain has been registered with this company for over 10 years. I am wondering if changing to a different hosting provider would have an effect on my rankings due to the change in IP.

Are dropdown menus bad for SEO
I have an ecommerce shop here: http://m00.biz/UHuGGC I've added a submenu for each major category and subcategory of items for sale. There are over 60 categories on that submenu. I've heard that loading this (and the number of links) before the content is very bad for SEO. Some will place the menu below the content and use absolute positioning to put the menu where it currently is now. It's a bit ridiculous in doing things backwards and wondering if search engines really don't understand. So the question is twofold: (1) Are the links better in a bottom loading sidemenu where they are now? (2) Given the number of links (about 80 in total with all categories and subcategories), is it bad to have the sidemenu show the subcategories which, in this instance, are somewhat important? Should I just go for the drilldown, e.g. show only categories and then show subcategories after? Truth is that users probably would prefer the dropdown with all the categories and second level subcategories, despite the link number and placement.

Does font size affect SEO?
In the eyes of Google, would the font text size of say a news article affect SEO? For example, a slightly larger font being easier to read by those with bad eyes? Accessibility? If so, what size would be ideal? 10, 12, 14? Your thoughts and suggestions are greatly appreciated.
