One can use specific search strings in most search engines to find if your URL is included in their index and also to see how many pages are thus indexed. These search strings have been identified and compiled by some useful resources on SEO.
For searching the pages from your URL in Google for example, insert the following search string in Google search:
allinurl:yourcompanyname.com/webmasters/meta.html (this depends on the index pages of your site). In the Yahoo directory use the command u:yourcompanyname.com to find the listings for this URL. There are similar, but specific search strings applicable to each search engine.
Again checking the search engine for your URL is a good way to check what that search engine has indexed. Thus through spider spotting and URL checking you have evaluated and confirmed the effectiveness of your actions on submission and indexing activities.
