Although submitting your blog to the search engines is very similar to submitting your website, there are several differences that you should be aware of. Knowing these differences can help you get your blog indexed more quickly because you have submitted your blog correctly.
Regardless of whether you are submitting a blog or a website, if you are submitting to Google, you should create a sitemap. Although you should check your sitemap periodically to make sure Google isn't encountering any errors with your sitemap, once you submit it, you don't have to submit to Google again. All you have to do is keep your sitemap up to date.
If you use a blog like Wordpress, you can install the sitemap plugin. This plugin updates your sitemap automatically and notifies Google that your site has changed.
If you don't use a blogging software that generates sitemaps, you can create your own. Google offers plenty of free tools for creating sitemaps.
Even if you don't have a sitemap, you can still add your site to Google. You just won't get detailed statistics.
Here's where you can submit to Google.
Since Google doesn't allow direct submission to its blog search, you will need to make sure that you submit your site to blog directories Google pulls results from for its blog search, and then make sure you ping these sites when you update your blog.
You can use sites like Feed Shot to submit your site to some of the major blog directories. Then you only need to ping your blog to update it at these directories.
When submitting to Yahoo, you need to submit your site feed instead of a sitemap. Here's where you can submit your blog to Yahoo . Instead of submitting your site, you will use the first block and submit your feed.
You should also add your blog feed to your My Yahoo page. This can get your blog added faster and will get your blog included in Yahoo's version of blog search.
