Confuse With Metatags & Google

Hi, i have submitted my website to google and 3 days later, it still not displaying on google. So i have tried adding some keywords etc to my metatags.php

Am i correct in just entering some keywords at:

/ page title
define('TITLE', 'Shulab.co.uk - Shoes & Accessories');

// Site Tagline
define('SITE_TAGLINE', '');

// Custom Keywords
define('CUSTOM_KEYWORDS', 'HERE');

// Home Page Only:
define('HOME_PAGE_META_DESCRIPTION', 'HERE');
define('HOME_PAGE_META_KEYWORDS', 'HERE');

// NOTE: If HOME_PAGE_TITLE is left blank (default) then TITLE and SITE_TAGLINE will be used instead.
define('HOME_PAGE_TITLE', ''); // usually best left blank

I was also wondering what's the difference with custom keywords and description? The Keywords am i limited to how many, or can i just name as many as i can think of? Do i also have to add anything at "Site_tagline"???

I will greatly appreciate any help, THANKS

Yea, that's fine, but meta tags really aren't indexed that well, anymore. The searches are mainly for content, these days. You should open an account with Google for the Webmaster Tools. Then get the Google Sitemaps mod from the downloads section. Then, when you get the sitemaps mod installed, set up, and your maps sent to search engines (explained in with mod), you should start to see you pages getting indexed in the next week, or so.
Also, in you content on you Index page, you'll want to pick out a good keyword or two, and try to use those several times throughout your sites description.

There's a little more to it than that, but that will give you a day or so's worth to do. Once you get set up with Google, you'll see that they have more to offer, also. Just follow all the instructions from the mod, Google, and keep in touch in the fofum, checking this thread, and searching SEO (Search Engine Optimazition), looking in the tutorial/FAQ section for SEO, and stuff like that. Next thing you know, you will search for your keyword(s) and see your site on the 1st page. Good luck.

Hope this helps.
