Smaller is Better

You often hear the phrase "bigger is better". Sometimes it's true but not when it comes to JavaScript or CSS code in your Yahoo! Store pages. If you include JavaScript code or CSS either as linked files (the preferred method) or embedded inside your pages (obviously not preferred), making these files as small as possible should be your goal. Why? This is no rocket science: smaller files mean faster page loads = happy customers.

Ok, so what bloats JavaScript code? In general, white space (tabs, carriage returns, non-used spaces), comments, and the actual code, such as variable and function names.

You have control over all of these, however, if you don't use white spaces, carriage returns or comments, it will be immensely difficult to understand and modify your code. And not just for others, you too.

There are many commercial JavaScript compression tools around, but I've been using this handy and free utility: http://www.andrewkesper.com/jscrush/

This little utility can take any number of JavaScript files and automatically remove white spaces and comments from those files resulting in files considerably smaller in size than the originals. There are a couple of other advantages of this tool:

1. You can use it to compress CSS files as well, not just JavaScript files.
2. You can have it combine your source JavaScript files into a single, compressed file.

Happy compressing!

This is a pretty cool tool. I will use it to condense my files.

What to expect when your redesign goes live

At Y-Times we roll out new designs, redesigns and other major upgrades to Yahoo stores on a fairly regular basis. Some of the main questions our clients ask are how to prepare for a roll-out and what to expect in terms of SEO and conversions when the changes go live?

For any functional Yahoo store how well the site ranks and how well it converts are probably the two most important metrics. Since pretty much ANY change you make to any page can potentially alter either or both of these metrics, merchants may understandably feel nervous about far reaching alterations to their sites. However, when those functionality and design changes and additions are done right, there is really very little to fear.

First off, what does it mean for a design or redesign to be "done right?" From the technical stand point, search engines look at the underlying structure of your site (the HTML, and increasingly also the CSS and JavaScript code) to try to extract information and meaning from it. If…

What is product-url anyway?

I keep having to field questions about the product-url field, and since it came up yesterday, I figured I'd try to clear up all the confusion about it.

So the name product-url suggests that whatever you type in there will become the URL of that product. Unfortunately, this is not the case, or rather, not in the intuitive way. The URL you enter there will be used as the URL for that product in Yahoo Shopping, on the built-in search results page, and on the shopping cart page, however, the URL you type in there DOES NOT actually change the physical URL of the page.
What is the URL of a page in a Yahoo Store? In any Yahoo Store built in the store editor, the URL of a page is the store's domain name and the page ID + .html. For example, in my store at www.ytimes.info, I have a page whose id is rtml101, thehrefore, the URL of that page is http://www.ytimes.info/rtml101.html.
Why would you want to change the URL? For SEO reasons, it is believed to be better to have a URL that includ…

Bookmarklets for Yahoo Store

I was introduced to "bookmarklets" by my friend, Rob Snell, many years ago at one of the Yahoo Store conferences and they are indispensable tools in my daily work on Yahoo stores.
What are "bookmarklets"? As the name suggests, bookmarklets are kind of like bookmarks in your browser, except instead of leading to a web page, they execute a small piece of JavaScript code on the current page. This is made possible by the browser's support of the "javascript:" prefix. When you point your browser to a URL, the browser figures out what to do with it: bring up a web page if the address starts with http:// or https://, connect to an ftp site if the address starts with ftp://, or in the case of javascript:, interpret and execute the JavaScript code following the colon.
Typically, bookmarklets are saved either in your Favorites folder or if you use them on a daily basis like I do, in your browser's bookmarks toolbar. In essence, bookmarklets are sort of like…
