Search engine optimization can be a time consuming process but there are several factors that go into it.
- Your site should have good keyword rich page titles and URLs.
- Your site should have keyword rich H1 tags on each page (only 1 H1 per page).
- Each of your pages should have keyword rich content that is fluent.
Don't try to stuff keywords.
Also, your meta keywords should be separated by commas. No point in going over 45 characters, the big three won't read past that number. Your meta description should also be keyword rich and 1 - 2 sentences long.
Once your insite SEO is done then you can go to external sites and ask that they link back to your site using quality anchor text such as "Electric Motors" rather than "www.electricmotors.org".
