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

Gallery maintenance and the effect on SEO
Basically we get a lot of users uploading photos as part of their review, but many photos aren't moderated into our pages and therefore are never displayed. Things like selfies rather than photos of the product or just random google images that are completely unrelated to our products or services. Is there any benefit in cleaning up the gallery since some images we don't use are just sat there in admin?

when a page loads, would it be quicker if we had less content in the gallery? With our SEO hat on.
or does it not matter since it's not loading that content (photos) anyway?0 -
Merging Pages and SEO
Hi, We are redesigning our website the following way: Before: Page A with Content A, Page B with Content B, Page C with Content C, etc
Intermediate & Advanced SEO | | viatrading1
e.g. one page for each Customer Returns, Overstocks, Master Case, etc
Now: Page D with content A + B + C etc.
e.g. one long page containing all Product Conditions, one after the other So we are merging multiples pages into one.
What is the best way to do so, so we don't lose traffic? (or we lose the minimum possible) e.g. should we 301 Redirect A/B/C to D...?
Is it likely that we lose significant traffic with this change? Thank you,0 -
How important is admin-ajax.php?
Hi there! It's been a long time since I last did a technical audit of a site. I've currently playing with the 'fetch as google' tool to find out if we're blocking anything vital. The site is based on Wordpress, and after a recent hacking incident, a previous SEO moved the login portal from domain.com/wp-admin/ to domain.com/pr3ss/wp-admin/ - to stop people finding it. Fair enough. But they then updated the robots.txt file to look like this: User-agent: *

Disallow: /pr3ss/wp-admin/ Now, some pages are trying to draw on theme elements like: http://www.domain.com/pr3ss/wp-admin/admin-ajax.php
http://www.domain.com/pr3ss/wp-content/themes/bestpracticegroup/images/column_wrapper_bg.png And are naturally being blocked (not that this seems to affect the way pages are rendering in Google's eyes) A good SEO friend of mine has suggested allowing the theme folder, and any sub folders where this becomes an issue. What are your thoughts? Is it even worth disallowing the /pr3ss/wp-admin/ path? Cheers guys and gals! All the best, John. I've found a couple of the theme's0 -
Are these URL hashtags an SEO issue?
Hi guys - I'm looking at a website which uses hashtags to reveal the relevant content So there's page intro text which stays the same... then you can click a button and the text below that changes So this is www.blablabla.com/packages is the main page - and www.blablabla.com/packages#firstpackage reveals first package text on this page - www.blablabla.com/packages#secondpackage reveals second package text on this same page - and so on. What's the best way to deal with this? My understanding is the URLs after # will not be indexed very easily/atall by Google - what is best practice in this situation?

Using WP All Import csv import plugin for wordpress to daily update products on large ecommerce site. Category naming and other issues.
We have just got an automated solution working to upload about 4000 products daily to our site. We get a CSV file from the wholesalers server each day and the way they have named products and categories is not ideal. Although most of the products remain the same (don't need to be over written) Some will go out of stock or prices may change etc. Problem is we have no control over the csv file so we need to keep the catagories they have given us. Might be able to create new catgories and have products listed under multiple categories? If anyone has used wp all import or has knoledge in this area please let me know. I have plenty more questions but this should start the ball rolling! Thanks in advance mozzers

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

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.
