If you don?t want too much competition from other SEO?s, choose your keywords precisely.
For example, Instead of keyowrd Loan choose keywords like Bank Loan, Equity Loan, Student Loan, Home Loan etc.
Order of keyword also matter for search engines. Search engine treats ?Loan Equity? and ?Equity Loan? as different keywords.

Best seo practice is to get at least one of your primary keywords in domain or sub domain name of your website.
You can use hyphens (-) to separate multiple keywords.
For example: seo-service, seo-guidelines, free-seo each cover two keyords.

Get your second or third keywords in your directory name and filename.
For example http://www.hiddentricks.com/seo/free-tips.html is best for keyword ?free seo tips? , ?seo hidden tricks? or "free seo tricks"

Keep your webpage free from any syntax error, declare document type at the beginning and validate your HTML and CSS because search engine don?t like pages with too many errors.

Give a short Title in of your page in 3-9 words (60-80 characters) maximum in length containing your primary keyword.
Remember it will be displayed in search results so choose wisely.
