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

URL structure for SEO
Hi Mozzers, I have a site which is a combination of product pages, and news and advice pages that relate to the products. How would you approach the URL structure for this, following SEO best practice? Approach 1 Product pages:
Intermediate & Advanced SEO | | A_Q
www.website.com/product-category/product-page News and advice pages:
www.website.com/product-category/product-page/news-and-advice-story-1
www.website.com/product-category/product-page/news-and-advice-story-2
etc or Approach 2 Product pages:
www.website.com/product-category/product-page News and advice pages:
www.website.com/news/product-category/news-and advice-story-1 (with internal linking to relevant product page)
www.website.com/news/product-category/news-and advice-story-2 (with internal linking to relevant product page)
etc Or would a different approach be better?0 -

Few question about SEO
HI guys, I have few questions and I always find good answer here. I tried many SEO companies some very expensive and well known some with medium prices and some from India. I’m not an SEO expert but I always get the same things from SEO companies. They're saying you have to stay with us for few months before you’ll see any results. I completely understand however I don’t see the result on the end.1. What exactly Do I need SEO company for, after I do on page optimisation if they don’t work on proper backlinks. Just letting you know I’m getting content from other people.2. Is there something else which is really important after your page is optimised than backlinks? Or we should fully focus on get backlinks from customers, guest post, sharing on social media etc. to increase our DA and PA?3. Any advice about some individual or company who is good in backlink services?

Seo for Q&A site
Hi, I am working on a newly launched Q&A site. We have very few questions and users right now and very very low seo traffic. In order to increase the number of users and seo traffic we intend to create a number of pages containing potential questions. Each page would have the following structure: Question. Ex: "What are the top wholesale suppliers of coffee in China?" Some content. Ex: Are you looking for wholesale suppliers of coffee in China? Post your question here? Question form Some additional content So there would be a page for wholesale suppliers of coffee for every country. We would publish the pages gradually and the content would be unique but yet similar (ex: only the Country changes). What do you think about this approach? Is it a good idea or can it be dangerous? We don't want to incur in any kind of penalization, we just want to give the possibility to people who are looking for specific information to find us and be able to post the request on our website.
