All major search engines such as Google, Bing and Yahoo have primary search results, where web pages and other content such as videos or local listings are shown and ranked based on what the search engine considers most relevant to users.
Here are some tips from Google’s
Create unique, accurate page titles
Choose a title that effectively communicates the topic of the page’s content.
<Avoid>
- choosing a title that has no relation to the content on the page
- using default or vague titles like “Untitled” or “New Page 1”
Make use of the “description” meta tag
A page’s description meta tag gives Google and other search engines a summary of what the page is about
<Avoid>
- writing a description meta tag that has no relation to the content on the page
- using generic descriptions like “This is a web page” or “Page about baseball cards”
- filling the description with only keywords
- copying and pasting the entire content of the document into the description meta tag
Improve the structure of your URLs
Simple-to-understand URLs will convey content information easily
<Avoid>
- using lengthy URLs with unnecessary parameters and session IDs
- choosing generic page names like “page1.html”
- using excessive keywords like”baseball-cards-baseball-cards-baseballcards.htm”
Make your site easier to navigate
Create a naturally flowing hierarchy and Use mostly text for navigation
<Avoid>
- creating complex webs of navigation links, e.g. linking every page on your site to every other page
- going overboard with slicing and dicing your content (so that it takes twenty clicks)
- having a navigation based entirely on drop-down menus, images, or animations
