Update: [May 1st, 2008 – 1:02pm] I have updated the Web Developer’s SEO Cheat Sheet (PDF) to include suggestions from comments. This new version has more useful information and clears up some ambiguity. Thank you to everyone in the comments who helped make this better!


When I first started at SEOmoz about 9 months ago, I was the web development intern. My experience prior to the internship was limited entirely to writing code. Since then, I have spent literally hundreds of hours expanding my knowledge into different areas. Specifically, I have focused on accepted SEO techniques and small business practices. My beginner SEO checklists of the last few weeks have been the tangible result of my newly acquired knowledge. In an effort to return to my roots, I spent the majority of the day compiling what I believe to be the mother of all technical SEO cheat sheets. The recommended viewing format of this cheat sheet is as a PDF rather than the traditional blog post (I found the blog posts inconvenient to print). Let me know if this new format works better for all of you. I also included snippets below so you can see what is on the cheat sheet before you download it. Enjoy!

I look forward to hearing from the more experienced SEOs in the comments. Please let me know how I can improve this sheet. If any of you (experienced or inexperienced) decide it would be preferable to contact me privately, please feel free to e-mail or private message me using the information available in my profile. Thanks!
