Why My Blog Doesn't Show in Google?
If you are worried about your blog not being listed in search results on Alexa, Bing, Clusty, Google, Yahoo or any other one, you're not alone. The answer - follow these simple tips, keep working and it'll show up soon.
1. Content is the king
We humans see a site while the search engines read the sites. The best you can do is to improve your contents.
2. Networking is important
Links are as important for your blog as references are for you. Get your blog linked from your own other blogs and sites. Ask your friends and family to link to your blog. Read other blogs and leave comments often. One referral from popular sites is more valuable than three from some vague one-page site.
3. Keep it clean
Don't even try to fool the search engines. The days of long and unrelated "keyword" meta-tags are over. Unrelated white keywords on white background just to fool the search engines can do you more harm than benefit.
4. Plain text before cool animation
Pretty images and an impressive Flash piece may make your blog look great but as far as search is concerned, the contents are immensely valuable. Don't forget to use tags such as "ALT" and TITLE" with your images.
5. Update often
More often you update, more visits you'll have from the visitors and more updates from the search engines. An average search engines is not interested in a blog that was last updated three three years ago.
6. Listen to the experts
There is good advice on the Internet to help you. Listen to the experts and get benefited.
7. Title matters
The title of your blog is very important and so are the headings. Use these judiciously.
8. Submit to search engines and site directories
Manually submit your site to search engines such as Yahoo, Google etc.
9. Have patience
You don't jump to the top overnight. Search engines may take long to completely index your blog. Remember, perseverance pays.
Following these simple tips will help you get a higher rank fast. Good luck!

Visual Studio 2008 extensions for Windows SharePoint Services 3.0 - Problem
When you try to install Visual Studio Extensions for Windows SharePoint services or SharePoint 2007 on your Windows XP workstation, it fails after displaying the following or similar message:
"This product can only be installed if Windows SharePoint Services 3.0 has been installed"
You don't have to install WSS on your workstation. Even if you try, it fails after showing a message similar to the following:
"This product requirs Windows Server 2003 SP1. Install this service pack and re-run setup"
I attempted a few workaround and then came across Umakanth's blog post that fixes this problem in one simple registry edit to make the setup program believe that SharePoint is installed on your workstation.
1.Run regedt32 and navigate to
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Shared Tools]
2. If there is a key "Web Server Extensions" get into it else create one
3. If there is a key "12.0" get into it else create one
4. Create the following string value
Name = Sharepoint
Value = ”Installed”
5. Re-run the setup and see it work.
Wait! Though the extensions are installed, your project may still show errors like "Could not load file or assembly" when you reference "Microsoft.Sharepoint" and other assemblies.
All you need is to drag the SharePoint assemblies from folder: C:\Program Files\Common Files\Microsoft Shared\web server extensions\12\ISAPI on your ShaerPoint server and drop to c:\windows\assembly folder of your workstation. Make sure that the files are from a 32-bit server.
