The difference between [-] dash and [_] underscore in asset naming

Over the weekend, I receive a few questions about naming convention that will help improve SEO. Although correct naming doesn’t have too much of an impact in SEO, it does help in certain situation when the crawler needs to infer the content of your page.

Some tips and tricks:

- If you are using space, delimit it by using a – instead of a _; to a crawler,
  this_is_a_page means “thisisapage” while this-is-a-page means “this is a page”
  so whenever a crawler wants to match a keyword, you will want to have zune-music-player instead of zune_music_player

It is also advisable to give meaningful names to your pages or pictures, 12312inwf23.jpg doesn’t help tell what the picture is to a crawler but zune.jpg does help a lot.

That same advice applies to all other files that you want the crawler to crawl to (e.g. .mp3, .jpg,. html, etc)

Introducing your site structure to a search engine

In order for the crawler to know which page to crawl, the crawler will try to infer the site structure either using sitemap or simply crawling the links on the main page. You can generate a sitemap XML based on specification located at http://www.sitemaps.org/ from http://www.xml-sitemaps.com/

A short introduction of sitemap: (abstracted from http://www.sitemaps.org/)

What are Sitemaps?

Sitemaps are an easy way for webmasters to inform search engines about pages on their sites that are available for crawling. In its simplest form, a Sitemap is an XML file that lists URLs for a site along with additional metadata about each URL (when it was last updated, how often it usually changes, and how important it is, relative to other URLs in the site) so that search engines can more intelligently crawl the site.

Web crawlers usually discover pages from links within the site and from other sites. Sitemaps supplement this data to allow crawlers that support Sitemaps to pick up all URLs in the Sitemap and learn about those URLs using the associated metadata. Using the Sitemap protocol does not guarantee that web pages are included in search engines, but provides hints for web crawlers to do a better job of crawling your site.

http://www.xml-sitemaps.com/ is a site with a free tool to generate the sitemap.xml.

After generating the sitemap.xml document, you will need to inform the crawler of this change: (abstracted from http://www.sitemaps.org/)

Informing search engine crawlers

Once you have created the Sitemap file and placed it on your webserver, you need to inform the search engines that support this protocol of its location. You can do this by:

• submitting it to them via the search engine's submission interface
• specifying the location in your site's robots.txt file
• sending an HTTP request

The search engines can then retrieve your Sitemap and make the URLs available to their crawlers.

Submitting your Sitemap via the search engine's submission interface

To submit your Sitemap directly to a search engine, which will enable you to receive status information and any processing errors, refer to each search engine's documentation.

Specifying the Sitemap location in your robots.txt file

You can specify the location of the Sitemap using a robots.txt file. To do this, simply add the following line:

Sitemap: <sitemap_location>

The <sitemap_location> should be the complete URL to the Sitemap, such as: http://www.example.com/sitemap.xml

This directive is independent of the user-agent line, so it doesn't matter where you place it in your file. If you have a Sitemap index file, you can include the location of just that file. You don't need to list each individual Sitemap listed in the index file.

You can specify more than one Sitemap file per robots.txt file.

Sitemap: <sitemap1_location>
Sitemap: <sitemap2_location>

Submitting your Sitemap via an HTTP request

To submit your Sitemap using an HTTP request (replace <searchengine_URL> with the URL provided by the search engine), issue your request to the following URL:

<searchengine_URL>/ping?sitemap=sitemap_url

For example, if your Sitemap is located at http://www.example.com/sitemap.gz, your URL will become:

<searchengine_URL>/ping?sitemap=http://www.example.com/sitemap.gz

URL encode everything after the /ping?sitemap=:

<searchengine_URL>/ping?sitemap=http%3A%2F%2Fwww.yoursite.com%2Fsitemap.gz

You can issue the HTTP request using wget, curl, or another mechanism of your choosing. A successful request will return an HTTP 200 response code; if you receive a different response, you should resubmit your request. The HTTP 200 response code only indicates that the search engine has received your Sitemap, not that the Sitemap itself or the URLs contained in it were valid. An easy way to do this is to set up an automated job to generate and submit Sitemaps on a regular basis.
Note: If you are providing a Sitemap index file, you only need to issue one HTTP request that includes the location of the Sitemap index file; you do not need to issue individual requests for each Sitemap listed in the index.

Where the “Live” Magic Happens

Have you seen Photosynth from Microsoft Live Labs?  Super cool.  Honey made a quick “synth” of the Online Services Group – Southeast Asia office area.

Check out other cool photosynths (and even create YOUR OWN) here… http://photosynth.net/default.aspx

Don't Know Where You Are? Maybe our "WhereAmI" Project Can Help...

Drum roll please....

After many months of hard work, we would to introduce the people of Southeast Asia to our "WhereAmI" project (http://locationpinpoint.com).  The goal of the project is to help facilitate location based services through FREE location-ing information.  Think of it as a GPS device that works off of WiFi and/or cell tower data and doesn't need to be outdoors.

I won't go into too much technical details but essentially:

• Input = WiFi access points you hear around you AND/OR the cell towers you hear around you
• Output = an estimated longitude and latitude of where we think you are

Doesn't sound like much but this is currently the key "missing link" to build much cooler (and useful) services to service scenarios such as:

• Are my friends around me?  If so, I'll give them a shout.
• I lost my phone but my phone will tell me where I left it.
• I want to find all the top rated restaurants around me but I'm not exactly sure where I am (or I don't know my exact address).
• I want to go home, which is the next bus that can take me there and where is the bus stop.

There are services like this here and there but they are all commercially executed (fees).  We intended to provide this service to the people of Southeast Asia (SEA) FOR FREE! 

Built by the people of Southeast Asia... for use by the people of Southeast Asia.

No, this service isn't a Microsoft offering but rather... something fun that we built on the weekends BY MANY OF YOU in the community (we have a few uni and poly students, a Singapore scholar and a few people at Microsoft).

The project has a few pieces:

• WhereAmI Service (the service you would use to query your location)
• Infrastructure (the gooey-goodness in the middle)
• Survey (the tools we use to survey the information which gets sent back to you when you use the service)

Here's a quick 2 min video on how it works and how it all comes together.

http://video.msn.com/video.aspx?vid=85238949-6807-47a9-b66b-c78427d41eb6

We're in the middle of an update from our test servers to something more robust to handle the public's load.  Will put an announcement when the service is up (in about a week).

Coverage is currently Singapore but we're keen to grow the service.  If you're in SEA and interested in offering this service to your region for free, we'll provide all the tools, equipment and infrastructure... all we need you to do is to help with the survey.  Feel free to drop me a note. :)

More exciting stuff to share shortly.  I'll also introduce the people who's hard-work is making this all possible.

Hello from Your Search Guy for Southeast Asia :)

First off, apologies for my readers in Singapore as it has been a heck of a long time since I made a post.  The past few months have been quite hectic.  I've changed roles (no longer your Developer Evangelist for Singapore) and am now your Search Guy for Southeast Asia!

Search Guy... what is that?  Good question, my goal is to help the people in our humble part of the world find and explore more on the web be this through our Search engine or our Maps.  Give it a try...

Our Search - http://www.live.com

Our Maps - http://maps.live.com

I've been sitting on this post for quite some time as it was hard to convey to all of you what it is we're trying to do.  Search and maps is only just one piece of something much bigger and focus is not at all on just one single dimension.  So instead of trying to write out some long essay... this video perfectly illustrates the "YOUR digital life" theme all of us here are working towards.

http://video.msn.com/video.aspx?mkt=en-US&playlist=videoByUuids:uuids:a8d98d01-7edf-4991-93b7-8554b9608b5a&showPlaylist=true&from=shared

Hmm... notice how Search and Maps are only a small piece of this whole "connected nirvana"?  If you think about it... the focus should be on YOU and how our efforts can complement YOU and what you do everyday.

There's lots of work happening behind the scene to make this more and more a reality for Southeast Asia.  Pretty much every piece of what you see in this video sits in or around my team here in Singapore.  They are all super smart and full of ideas.  I wake up everyday excited to go to work as I know there's much we can do to make all our lives more fun.

If you keen to know more about what we're up to or want to make a request... reach out and give me a shout.  I'll be starting to ramp up my community presentations soon so you can always reach out then.
