The first hint is to create quality pages,when you got something interesting to say people will browse through your pages and trust your product.The possible client might even return later to buy the product.
If you don’t have anything interesting to say don’t even think about starting,you will end up loosing the client.
On your pages only handle one general subject,write content that uses relevant keys.
When your page is about SEO use keywords like “google ranking”,”higher search engine ranking”,etc..
Put the subject of your page in the name of your page file and separate multiple words with a dash.
When your page is about “ranking higher at google” us ranking-higher-at-google.html or ranking-higher-at-google.php
This should bring your page up at the google rank.
Put yourself in the position of your customer,which words would you type into google to get to your own webpage.Think about it,write down those words in notepad and use them in your texts.
