Be distinctively better than other websites in your field. Create unique pages that help, delight and impress users.
The most important thing that affects your ranking on Google is how much people are satisfied or pleasured by your webpages.
Useful and information-rich pages are what users crave. Your users should find content that is original and solves their problems.
The way your website is organized defines what is important to your website. Using text links ensures that those links are functional.
Accurate and descriptive webpage titles are essential for a healthy website. Alt tags should describe the image, not your keywords.
Site maps should be a useful way for your visitors to quickly and easily find the information they are seeking on your website.
If Google can not see or understand your webpages, they can not be ranked in Google. Make sure your webpages are understood by Google.
The content of your robots.txt file tells search engine crawlers how they should visit your site. Don't block Google by mistake.
Blocking pages that do not add much value can really boost your rankings. Every page Google has indexed from your site should be amazing.
Paid links and advertisements should not pass pagerank. If it does on your webpages, you will likely be penalized.
Spend time improving your webpages, not on SEO tricks or shortcuts. If you use tricks or shortcuts, you will be ranked lower than your competitors.
Affiliate web pages need to have original useful content to be ranked well in the Google results. Use of content provided by another website adds no value.

Keyword stuffing is not only bad for your users, it is against the Google guidelines. Using keywords over and over unnaturally will not please your users.
Don't be mean. Adding viruses, trojans, or other badware to your webpages is a sure fire way to lose trust, traffic, and ranking.
Misleading or false information in your rich snippet mark up will result in lower rankings
Too many links can overwhelm a user. There are not many good reasons to have several dozens or hundreds of links on one page. Make sure every link has a truly good reason to be there.
Make sure you are using words that accurately describe your content and include words in your website that are relevant for searchers.
Text is well understood by search engines, images are not. If you use images for important links on your page, they might not be understood or recognized as well as text is.
No one enjoys clicking on a link that seems to be exactly what they are looking for only to find that no web page is there. Correct HTML displays well across different browsers and devices.
