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

SEO on dynamic website
Hi. I am hoping you can advise. I have a client in one of my training groups and their site is a golf booking engine where all pages are dynamically created based on parameters used in their website search. They want to know what is the best thing to do for SEO. They have some landing pages that Google can see but there is only a small bit of text at the top and the rest of the page is dynamically created. I have advised that they should create landing pages for each of their locations and clubs and use canonicals to handle what Google indexes.Is this the right advice or should they noindex? Thanks S

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!

Advanced SEO - What would you do after you run out of keywords?
Hello! Our company has been growing in terms of traffic and ranking well for a couple of years but we are now kind of stagnating because we just don't know what to do next. We have a good blog - and with our blogs, we have been targeting all major keywords with their related keywords as a bucket. - "keyword theme / page" for a long time. But it seems we now don't have any major keyword theme to write about. What is worse is that we don't see any traffic growth since 2014 September. (although we added many good blogs) So what would do you when you run out of keywords? or keyword themes? Would you just keep pumping in more blogs and hope that you get more clicks? or at some point, you just don't care about keywords and write whatever relevant to your site? Wouldn't it hurt our site if we create similar keyword themed pages? (like regurgitating our keywords?) or even same keyword targeting pages? You must have similar experience if you are an owner of a niche site. Can you please share your experience with this kind of headaches? Thank you and look forward to your comments.

Is tabbed content bad for SEO?
I work for a Theater show listings and ticketing website. In our show listings pages (e.g. http://www.theatermania.com/broadway/this-is-our-youth_302998/) we split our content into separate tabs (overview, pricing and show dates, cast, and video). Are we shooting ourselves in the foot by separating the content? Are we better served with keeping it all in a single page? Thanks so much!

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.

Web fonts & SEO
Hi everyone ! My question is regarding web fonts. We are currently working on a new design for our website and we're thinking about using web fonts instead of images containing the fonts we'd like to have. I'd like to know if web fonts can affect SEO as they need to be downloaded on the visitor's computers and consequently can slow down the load time of our web pages. If anyone has used web fonts in the past, do you have some specific tips to share ? Thank you in advance for your answers! Jeremie

URL Shorteners. Are they SEO Friendly?
Do URL shortener services like bit.ly act as 301 redirects? I was thinking about utilizing one for longer query based URLs and didn't want to risk losing link juice. Thanks for the insight! Regards - Kyle
