L) Content
Add a page every 2-3 days: 200-500 words. Create original content, don't copy others. The more original and useful it is, the more people will read it, link to it, and most importantly of all - like it enough to keep coming back for more.

M) White Hat Only
Stay away from black hat optimizing techniques. Black hat optimization consists of using any method to get higher rankings that the search engines would disapprove of, such as keyword stuffing, doorway pages, invisible text, cloaking and more. Stick to white hat methods for long-term success. People who use black hat optimization are usually there for the short-term, such as in porn, gambling, and Viagra markets (just look at your email spam for more black hat markets). These black hat industry sites are usually around just long enough to make a quick buck.

N) Competition Analysis
Who is linking to your competition? Use Yahoo's "link:" service to see the back links of your competition. For example, type in "link:http://www.yourdomain.com" into Yahoo search without the quotes). Try to get links from the same sites as your direct competitors. Better yet, see if you can replace them!

O) Submit
Submit to five groups of directories:

1. Dmoz.org and Yahoo (local, such as Yahoo.co.uk, or Yahoo.ca, etc... if you can).
2. Find directories in your field and get into them. Pay if you must, but only if the price is reasonable.
3. Local directories that relate to your country or region.
4. Any other directories that would be appropriate.
5. If you are targeting the local market, make sure that you are in the Yellow Pages and Superpages (because search engines use these listings to power local searches)
