This usually occurs towards the last week of each month. If you have any site or page changes, I require a minumum of two weeks notice for any changes on my end. Now the wait begins. Most search engines will not index your submissions for 4 to 6 weeks. Viewing your results takes a bit of time.
Prompt payment is required.
If you want free services, try promotion your site on your own. Most promotions exceed 1200 total submissions. I guarantee 600 minimum count. Please review all the information I have here before deciding what you need. My rates are below the fair market value.
