QUALITY CONTENT that is relevant to the site and page, then the basics, start with the Title, then relevant keywords that aren't overstuffing the page.

I do all of the above. I also make sure that I use the alt tag for my images.

I have a website that ranks at or near the top of Google for most keyword search terms and I modified the title, I didn't change the whole title just part of it. Once Google crawled my website, my website rank dropped like a rock. My website could not be found on Google for most keyword search terms after I modified the title. Luckily I was monitering this and as soon as I saw that Google had crawled my website I changed my title back to what I had originally and my high search engine ranking was restored. I didn't make any other changes to my website, just to the title. So there is your answer. This happened about 2 months ago.

According to me good and UNIQUE content is the most important factor after that the domain age is also a big factor.

There are many key factors which can help you the most in achieving the good rank they are as following as:
1.Domain name
2.Good Title
3.Simple Keywords
4.Description meta tags
5.Header Tag
6. Your Good content
7.Site map
8.Avoid Cheating

backlinks is the king as well as content.

for me backlinks, keywords and a good content will help my site ranks well.
