The Science of SEO: A Periodic Table Of Search Ranking Criteria

SEO (Search Engine Optimisation) can be a tricky thing to explain let alone master.

It’s this simple if you want your site to rank well on Google, Bing, Yahoo and any other search engines then your site and content need to fully optimised to help those engines find your content, evaluate it and give it the ranking it deserves.

When trying to explain SEO to people not in digital you may encounter some blank looks and a fair share of suspicion. But maybe it’s easier to break I down like this:

SEO Done Right = Traffic, Conversions, Visibility, Loyalty, Engagement and REVENUE!

Like I said its hard to work out what are all the factors that defined a good SEO strategy (it doesn’t help that much of Google’s algorithms are shrouded in mystery). So I’m always on the lookout for interesting ways to convey that info and other tips to use.

The guys at Search Engine Land put together this SEO chart based on the periodic table. It outlines key ranking factors and best practice you need to consider when building your sites and writing your copy to get a good search rank:


These elements are in the direct control of the publisher and includes: Content, HTML and Architecture


Elements influenced by readers, visitors & other publishers including links, Trust, Social and Personal factors.


All factors on the table are important, but those marked 3 carry more weight than 1 or 2. No single factor guarantees top rankings or success, but having several favourable ones increases the odds. Negative “violation” factors that can harm your chances are in red .
