Combining CSS
-
One recommendation from a page speed analysis of my site was to combine CSS (external style sheets) but after reading more on the topic others say that this is not always best. Any thoughts on either approach?

Hi Brett,
The reasoning behind combining CSS files is to reduce the number of files that need to be requested when the page is loaded. If you load one CSS file instead of five CSS files, your page should load somewhat faster. This is especially true when dealing with larger CSS files (for example, five large CSS files combined to one really large CSS file will usually make the site load faster). I'd recommend combining CSS files if you can. Depending on what system you are working with, and how much control you have over the code, you may not be able to. What reasons were given to not combine files?

Optimize CSS Delivery
Hi, I am loading 3 CSS files here: http://www.viatrading.com/wholesale/9/Domestics.html PageSpeed is telling me I "should fix" the delivery of these CSS Files (see image). I read https://developers.google.com/speed/docs/insights/OptimizeCSSDelivery , but can't figure out which is my case. The CSS are big, but even if I split them in several, all CSS files are still showing up as render-blocking. I moved them to the header/footer, but the message is still appearing. Do you know what might be the problem and how to solve it? Thank you, Screen_Shot_2015_09_10_at_4_44_23_PM.png

Having a terrible time ordering the CSS Styles and Scripts in my header
Hi Guys, I am having a terrible time trying to get the correct optimized (for speed, none blocking etc) order for loading my external css and JS. I follow the recommendations from Google Page Speed or Chrome Audit and it seems no matter where I move the CSS file too (top or bottom) it complains about more blocking and stopping rendering of the page. My URL is http://www.MyFairyTaleBooks.com if some smart person out there could help me figure out what I am doing wrong and the order in which my should be organized I'd appreciate it! Oh I'm not a developer but I can re-arrange text in a file! 😉 Thank you!

If I put 'keyword/url' combination to 'stop run weekly', will it dissapear from the summary page in the on-page grader?
The summary page of the on-page grader chooses the keyword and url combination itself. Now if I choose another combination, I would like the former to dissapear from the summary page. The only option is 'stop running weekly'. But will it disappear from the list also?

Html and css errors - what do SE spiders do if they come across coding errors? Do they stop crawling the rest of the code below the error
I have a client who uses a template to build their websites (no problem with that) when I ran the site through w3c validator it threw up a number of errors, most of which where minor eg missing close tags and I suggested they fix them before I start their off site SEO campaigns. When I spoke to their web designer about the issues I was told that some of the errors where "just how its done" So if that's the case, but the validator still registers the error, do the SE spiders ignore them and move on, or does it penalize the site in some way?
