One question that often comes to the mind of anyone who is trying for the Search Engine Optimisation is whether it requires continuous updating and maintenance. Typically, it is not required to maintain your search engine optimization every month. You could use long term strategies for success in the process based on professional expertise and technical knowledge. 

You have to appreciate the nature of search engine to understand the process of Search engine Marketing. They are computers with databases containing billions of URL. When the user types in the key word or key phrase, the search engine will look into its database and display the best sites on the basis of their respective relevancy to the keyword or phrase. They will enlist only the unique and relevant and not anything else. 

Moreover, Online promotion has now reached a stage where most of the search engine check out for mass submission sites and discard them. It is therefore prudent to submit your site directly to each of the engines or portals.  There are some of the search engines that would require only an annual submission for small fees. 

You should refrain from using the services of such agencies that claim to submit your website to thousands of different search engines on the web for a paltry amount. Most of the services are not only outdate but can have a negative affect on your ranking instead of giving you the desired page ranking on the search engine result pages.
