There is the option of free search engines like GOOGLE, ALTAVISTA,ALLTHEWEB,YAHOO and many, many more.
They can find you in three ways:

1. you submit your web site to them fro free.
2. you PRIORITY submit your site to the them.
3. you pay the "Free" Engines to include you in their prime spots.
4. by crawling the internet day and night

1. Free Submissions.
Pro:
- The best thing about this sort of submission is that it is free. We always recommend to submit for free. Why pay when you can get it for free?
- No yearly renewal fees.
- All traffic and business received from free listings is 100% profit.
- Anyone can do a free based submission, it is very easy to do.
- With specialized submission software like SubmitWolf Pro v6.0 you can submit to hundreds of search engines and thousands of link pages in just a couple of minutes, saving you a lot of time.

Con:
- Time. If specialized submission software is not used with the vast number of engines you can submit to, it can take you months of your time to hand submit to all of them.
- There is no guarantee that your page will be accepted by the search engine.
- Those sites lucky enough to be indexed can expect listing times ranging from 1 month up to 6 months.
- Free site listings are not updated frequently by the Search Engines. Usually on a monthly basis.

2) Priority Submit 

This means your website will be added to a search engine much faster then if you use the Free service.

Pro:
- For a small fee you can have your site listed in a major search engine within 48 business hours.
- Different engines have different prices catering to small or large websites.
- Compatible with all sites especially dynamic ecommerce sites which have trouble being listed via the free services.
- Greater reach as many engines use and display results from other engines, such as Inktomi, Fast and LookSmart provide results to many other engines.
- Your page is spidered every 2-3 days which means any changes you make to your site will almost instantly be reflected in the search engine.
- Easy to manage if using a system like PrioritySubmit.com
- Some engines provide detailed traffic stats. Great to measure ROI (Return On Investment).

Con:
- Can become expensive when you want to submit multiple pages to the search engines.
- If you are not using a system to manage submissions then you will need to open an account with each engine making more work for yourself, more accounts and reconciliation's.
- Paying for submission is an added cost that can reduces your profit margins.
- Usually a yearly service, which means that you need to budget for each year of service.
- Paying does not generally improve your rankings, so you need to make sure this is also looked at, as no point pay for inclusion if you do not come up for the relevant search terms.
