What am I missing from this meta-tag coding? My website doesn't show up at all on search engines.?

Can someone that knows about programming help me? Below is the code I put in my website:

<head>
<title>Simple Ads – your company brander</title>
<meta name="description" content="Ad agency, Marketing, Printing & Web development">
<meta name="keywords" content="logo design, custom logo, custom logo design, cheap logos, cheap logo design, affordable logo design, logo development, logo, logo designs, logo designers, design, designers, designs, custom designs, business cards, business card, professional business cards, cheap business cards, affordable business cards, Orlando, FL">
<meta name="author" content="Simple Ads">
</head>

Am I missing something? I’ve done some research and I’ve read on "Robots" but I don’t even know what "Robots" are. What more do I need to show up on search engines… perferably top 10. Thanks in advance!!

I need to know about meta tags in a website… How can I get good placement with this set up?

I have my website set up with an entrance page because it shows a bit of adult content. The problem is.. I have all my meta tags (keywords, title, description, etc) set up but when I go to a meta tag analyzer to see if my site is search engine friendly I get very low results because my entrance page doesn’t have barely anything on it. If i type in the exact address of a different page on my site -such as my products -it’s a whole lot better. But, I dont understand how robots and search engines work this. Will they go through and see the rest of my site -keywords and such.. or is it more based on just the first page? What’s the best way to accomplish a high site ranking/listing with this type of setup?
