There are lots of ways to improve how high your site ranks on major search engines, and we've highlighted six to get you started:

1) Add Unique Content to Your Site
Brainstorm keywords that your audience might use to find you. Anytime you add content to your site — blog posts, product descriptions, etc. — it should be rich with those keywords. Unique, quality content also gives other sites reasons to link to you, and building backlinks is part of the popularity factor search engines pay attention to.

2) Place Keywords in Key Places
Those same keywords should appear in your page titles, headings and subheadings (in terms of content and code). However, that doesn't mean you should cram them anywhere you can. Use them where they're relevant, and if they aren't relevant in certain places, replace them with words that are.

3) Create a Sitemap
Sitemaps can improve SEO by displaying links to pages on your site that search engine bots might miss otherwise. Structure your site's pages from broad to specific, and try to keep them no more than three clicks from the homepage. Google Webmaster Tools, available via your control panel, explains how to create sitemaps and submit them to Google.

4) Add Links with Strong Anchor Text
When linking to relevant sites, tell your readers where you're sending them. The anchor text (the wording displayed in a hyperlink) should closely match the URL you are pointing to.

5) Getting Backlinks
This is one of the most important SEO aspects today. Search Engines like Google determine your site and pages popularity based on the number of backlinks from other websites. Links from relevant, quality websites in your niche is what you will be looking for.

Quality inbound links from other sites to your own are essential for search engine optimization for all but the least competitive keywords. It’s easy for a number of different pages’ on-page SEO to be similar which is why inbound links have become the determining factor for deciding who gets to the top.

It's also why link building techniques and skills have become the most prized in SEO. And relevant quality links are now so important that people pay thousands of dollars for them, even though Google disapproves paided links and will discount their value if it knows about them.

Relevant links are links from sites or pages with related content and (ideally) with link text related to your targeted keywords.

Quality links are unique text links inside body copy, preferably on sites that search engines can trust, eg, old sites with a history of their own quality inbound links.

6) Use common sense
Check out the SEO leading websites like Search Engine Land and SEO forums. Aks questions, adapt strategies that proofed to be working and use your common sense.

There are many more ways to improve your rankings and search engine optimization takes time, but sticking with it will help establish a strong visitor base for your site(s), or expand your online business through increased sales.
