blog for website?

I have seen that many good websites have blog.
I have few questions about it.
Is creating blog for website help to increase traffic?
What will be the better host blog at your own or host on other blog hosting websites like blogger.com?

I am planning to create blog for my website on subdomain. I plan to use wordpress. Is it ok? I want website blog should be listed in blog lists in blogger.
What can I do for it?

A blog by itself is not going to help. If you've got good content, you'll get traffic anyway, not necessarily through a blog.

Except for the difference in domain names, I don't see any advantage to using one over the other.

Wordpress is fine, but you can't get it listed on Blogger - they're two different services.

Why not just place a blog section together with the other navigation of your main site. I saw a video (sorry can't find it) before that encourages webmasters to do this. In this manner, you will be able to pass the link juice around the site by doing internal linking.

If you have good content on the blog, it would certainly help. I use blog to support sites usually posting related articles and that helps pull in some traffic.

Best part is it will help your main website with SEO.

You can find a lot of informative websites at the top of Google and other search engines that do not have blogs and their pages are in simple Html form.

Blogs by themselves are no guarantee for traffic but due to their special operations, ease of use and maintenance and the quick indexing, they have been liked by many webmasters.

wordpress or zblog are ok.

I have made 2 blogs. I use wordpress and blogspot. I haven't optimized those blogs. But I ever heard that if the blogs are optimized, they can be used to increase the traffic to a website.

Blogs are always helpful for website promotion. It increase website's traffic and visibility in search engine result pages.

I think blogs can help your site to have more traffics..You can use either blogspot or wordpress..Or you can put a blog on your website..

Using a blog for a website is a good idea!

You can use use it on website navigation or use another wordpress or blogspot Blogs with good and quality content

If you update unique post on your blog new user visit your blog and your website traffic increase..

Blogs can increase the traffic of your website ,but there're also exist other methods to promote website, use signature is one of them.

Blogs are really efficient way of promoting a website.
