Why is my website not ranking on Google?

[Richard]

Basing it from your explanation, it seems you are aware of the basics of SEO. With the latest Google revisions, all you need to do is tweak your techniques and adjust them accordingly. Some tips:

1. Vary the anchor text for your link types using these:
exact keywords.. example: Dee Why conveyancer and a variation of it.
url keywords... example: http://www.mothersinlaw.com.au
brand keywords...example: mothers in law or mothers in law lawyers
random keywords such as 'click here', 'find out more' etc.
THE KEY is to keep it natural

2. get links from different sources. Analyze competitors and see if you can get backlinks from their sources

3. Use different profiles when doing SEO
4. Use different IP address or browsers whenever possible
5. Make the most out of social media. Search engines not just crawl text based links but also decide based on visitor-website interactions
6.Link to internal pages, not just home page
7. Combine both nofollow and dofollow
8. To avoid penalties, be mindful of your backlink quantities. if the top competitor only has 100, then you better not have 1000!
9. Distribute linking over a span of time
10. Keep links relevant

It may sound ironic but the idea is to acquire web presence without making it seem like you are doing SEO. Above all, make sure that your visitors find your site content to suit their needs and expectations. Hope this helps.
