What does Google PageSpeed measure?

What does the PageSpeed tool actually measure?
Does it say that a webserver is fast or slow?
Thanks in advanced!

I agree. I think it's primarily is a measure of the DOM efficiency of the code it self and how efficient it is when rendering by a browser. Server speed is a minimal part of it. All the caching in the world does not make it faster for to restart the rendering because of inline css. A faster responding server and download of the page only makes it possible to start faster with 90% of jobs that are relevant for PageSpeed but which are mostly handled by the browser alone?

In a lot of respects, it measure the efficiency of your site. How well the code is optimized as well as your server in processing that code. It is possible to have a poorly coded site which performs OK because you compensate for the bad code/bad layout by having more horsepower. The server is definitely correlated to the pagespeed rank. It's likened to a big differential equation with 100 factors all playing a role in the final output, but several of the items contributing to the majority of the output behavior.
Check out some of the documentation on it: https://developers.google.com/speed/docs/insights/about
The raw horsepower of the server is only going to get you so far. You would be much better off designing a system with a small server which is super efficient, than spend tons of money on the top of the line server which is using all of its power to process inefficient code, assets, etc.

Google Search Console - Sitemap
Hi all, Quick question. I'm trying to update my sitemap via Google Search Console using a sitemap.xml file that I've created with ScreamingFrog. However, when trying to submit it, it seems that Google only allows sitemaps that are located at a path within your domain (i.e. www.example.com/sitemap.xml) as opposed to being able to directly upload a sitemap.xml file.Is there any way that I can easily upload my sitemap.xml file? Or is there any easy way that I can upload the file to a path on my domain so I can upload via the URL?Any insight would be much appreciated!Best,Sung

Vanity URLs are being indexed in Google
We are currently using vanity URLs to track offline marketing, the vanity URL is structured as www.clientdomain.com/publication, this URL then is 302 redirected to the actual URL on the website not a custom landing page. The resulting redirected URL looks like: www.clientdomain.com/xyzpage?utm_source=print&utm_medium=print&utm_campaign=printcampaign. We have started to notice that some of the vanity URLs are being indexed in Google search. To prevent this from happening should we be using a 301 redirect instead of a 302 and will the Google index ignore the utm parameters in the URL that is being 301 redirect to? If not, any suggestions on how to handle? Thanks,

Google authorship syntax, plus no follow
I have seen two forms of rel=author syntax. Are they both valid? (1) (2) Second, does 'no follow' take away authorship? Is there any point in doing rel=author for a link that is rel=no follow? Like this:

Do Google Always Tell You About Penalties?
Hi One of my clients has recently suffered a big decline in rankings on some of their keywords, going from positions in the top 10 to sub 50 for some of their keywords, but not all. Their website is still indexed and there is no link warning from Google. Some of their links from a previous link builder are dodgy and we have already tried to contact the other company for removal but to no avail. Any ideas where I start? So far I planning to increase the branded anchor link and add some content as the site is fairly light on content. Is it worth doing a reconsideration request and mention the bad links incase this is the problem. Has anyone seen any particular good resources on what to do when it appears you have a penalty. None of my other clients have been effected by Panda or Penguin and although I have done some general reading I need to know what action to take and get up to speed FAST! Thanks in advance. Kind regards Karen

Google.com
Hi We are managing a .com site for a client working on getting the site ranking. The site is hosted in the US. The content is rich, deep and unique. The site is in a competitive market but had begun ranking top 50 for a selection of keywords and we could see many more in the top 100. The site is now going backwards and only has a few keywords ranking top 50 and all the others have disappeared from the rankings all together. Any thought as to what could cause this. The site is managed from the Uk but as mentioned is hosted in the US. No penguin issues as all content unique, rich, relevant and fresh. SEO is also managed from the UK. Thoughts

Will google let me do this
Hi i am working on my site at the moment www.in2town.co.uk and i am adding new sections and was thinking about buying domain names that best describe that section and which people would remember. so for example i am looking at adding a tenerife magazine to my site and would like to know if it would be wise to buy a domain name for example tenerife magazine and then have it directed to the section of my site. would this benefit my site in any way and would google allow this. instead of having in2town.co.uk and then tenerife magazine after it, sorry cannot find the slash as i am on a spanish keyborad at the moment, i would like to have something like tenerifemagazine.co..uk etc If anyone can give me advice on this then that would be great. also can anyone let me know if this is a wise idea or not, to have sub domain names on my main site. i would like to know if i had tenerifemagazine under the in2town domain name would it slow the site down or should i consider building a brand new site just for that and then making people aware that it comes under the in2town umbrella many thanks

What pages of my site does Google rank as the most important?
If I type site:youtube.com into Google, are the results listed by what Google considers to be the most important pages of the site? If I change my sitemap should this order change? Thanks!
