CloudFlare describes Rocket Loader like this...
coupled with a lightweight virtual browser which can safely run any
Rocket Loader does a bunch of things:
It ensures that all the scripts on your page will not block the content of your ...
Sure. Obviously, it would be better to use CSS alone but if you can't, use what you have. Do as much as you can with CSS and use JS as needed. Not sure why you can't change the existing CSS but you can add a style sheet with JS.
//create a new element
var newStyle = document.createElement("link");
//set the required attribute for a ...
Nice question, here are some guides for doing that on that level.
1. CRAWL YOUR SITE
When you redesign your website, there’s a good chance that URLs will change. If URLs change, you absolutely have to inform the engines where those older URLs have moved to. If you don’t, you can destroy your SEO power. All of the equity those old URLs have built up can ...
The CDN should be used for all static files (.css/.js/images).
If your CSS and ...
You have no control over them because they are hosted by another provider. And honestly speaking you should not worry about them, it's up to Google, Facebook, etc to handle the caching accordingly to their need.
You could potentially proxy the URLs or download the files locally, but I don't encourage you to follow that route. In fact, you may potentially ...
This wasn't possible when you asked the question. This is now possible with PageRules.
Note: You want to exclude the admin section of your site with a PageRule as well. If you do cache everything and the admin section is included, you will likely see some sort of looping error.
Well its not your site, its China's internet service layout, which has to jump through hoops to get even get to US DNS Servers. Furthermore, I don't know how 'free' the Internet surfing is there, meaning if it's being monitored by the government, which would undoubtedly further slow its response times. Many factors can be attributed to your site being slow ...
I would certainly recommend caching the tweets in your database or a plain text file. As soon as you start getting a lot of traffic you will be creating many hits to the Twitter API and going over their limit. And since you're not tweeting every 30 seconds day and night (I hope!) you could just end up fetching the same thing over and over.
In terms of ...
the other 4 are only used for a word or two
Is that a literal statement?
If so why are you bothering to embed these fonts at all, subsets or not? You shouldn't even be optimizing in this case, just removing. Make images of the text you need and use your favorite text-replacement technique. You're adding HTTP requests and download time to your site for the ...
Based on your reference to the ImageMagick convert method and quality parameter, it appears you're working with JPEG images. If that's the case, the EXIF information for JPEG images does not have a standard compression level tag.
However, ImageMagick appears to be able to obtain this information from the image's quantization tables using the identify ...
since you asked just out of curiosity, I wanted to comment on something .
you wrote that loading will take "few MS." well - this is not ALWAYS true.
Depending on your target users - sometimes it can take up to 3 min !!!
For example, I am right now in CHINA , which , as you know, BLOCKS twitter, facebook, youtube etc. the result : your page will have to wait ...
I don't think you're really getting the full picture with those figures.
Sites optimized for "free videos" will turn up for users searching for freevideos. Sites optimized for "freevideos" are much less likely to turn up in the results for free videos.
You can easily use natural synonyms for "free videos" (e.g. free movies, cost-free videos, public videos, ...
Please note: I am answering based on what you've described above only (which, while descriptive, isn't the same as analysing the source(s)).
To your questions above:
From Google Page Speed's own FAQ:
Some of the suggestions differ from the Page Speed browser extensions. Why?
Page Speed Online uses a different rendering engine and user agent, which may ...
You can then take these out, cleanup the file names, and reuse them.
Download Google Page Speed extension for Firefox
You could try http://www.smushit.com/ysmush.it/
Click "Uploader" and select all images that needs to be "smushed".
Your files will be uploaded to their server, become optimized without quality loss, and you will then be able to download all images in a zip file.
Adding the height and width attributes to your IMG SRC HTML tag allows
the browser to know how much space to leave for an image. Without
these values, the browser gives an image no space until the image is
loaded, which means anything surrounding the image is adjusted after
the image has loaded.
In addition to post-launch actions, I don't think you should completely ignore what's already there. You're speaking in future tense, so I presume the new site isn't ready yet; use that to your advantage and do a bit of tidying before you even make the switch.
If you have pages that will have a replacement (to which you'll want a 301 redirect) then take a ...
I don't think the modern search engines care about "older" phone compatibility. If the site is mobile-friendly in modern terms, the spiders will detect that and search engines that report it, will.
I suppose you could waste your meta description and/or the opening sentence of text on the site to declare that you are backwards compatible with Nokia flip ...
This is a design limitation:
The file size must be between 1,000 and 10,000,000 bytes.
Compressing files is resource-intensive, so the designers of CloudFront placed an upper bound on the size of files that CloudFront will spend resources compressing on-...
Ideally, the Content-type should be specified in HTTP headers (and the text/html part almost certainly is). Failing that, the declaration must be within the first 1024 bytes (usually 1024 characters) of the document.
The best way to ensure this is putting it right after the <head> tag. If you are using HTML5 you can simply use <meta charset="utf-8"&...
This heavily depends on the target of the audience.
For developers, I would offer a Login via Github. For all other matters, having a sign in via Facebook AND Twitter would not hurt.
What my company tough observed was, that even tough we are offering the login via Twitter and Facebook, 95% of the Users just sign in via a regular new account.
Enter that website's url into www.opensiteexplorer.org (or any other backlink checker) and you'll see it has lots of backlinks from a variety of domains.
You can further use other toolboxes (sistrix, searchmetrics, xovi, seolytics...) to analyze the value of the site over a period of time to see if there was a sudden spike of links or if the link building ...
Assuming the HTML page is of a reasonable size (back in 2006 it was 500kb, now it's likely much more), Google doesn't care about your pages' text-to-code ratio. Focus on creating great content instead, don't worry about your markup from an SEO point of view.
From a user's point of view, having a fast-loading page is great (so take care of unnecessary fluff,...
I would say try using media queries first. One method I found easier when dealing with a design that was originally only for desktop was this:
Start with two separate stylesheets. One for the new responsive design, and the other for the old desktop version:
<link rel="stylesheet" media="screen and (max-width: 959px)" href="css/mobile.css">
Unfortunately, you most probably won't be capable of measuring the SEO performance of the page before and after on-page optimization. The reason is you can't freeze the search engines for a period of time for your keywords. Search engines continue to calculate positions during the time where robots (web crawlers) index your page page for the first time and ...
When I want to do SEO changes and measure the results, I change half the pages on the site. This works best if you have a site with lots of similar pages that get similar amounts of search engine traffic. To make it work:
Divide your pages into two groups, randomly if possible. I generally use the content id for each page and do even and odd.
Google is attempting to append your site name to your title. Most sites put the site name at the end of titles themselves because:
It is good for branding
It differentiates your listing in the search results and makes users more likely to click
Its better at the end of the title than at the beginning because having the site name get truncated isn't a big ...
