Wrong,
TRUE SEO hasn't changed since 1995, it's only the short sighted "rankings are everything", algo chasing type of 'SEO' that has to be re-invented every time Google changes anything, and in a typical year there are around 500 adjustments made, anyone of which could kill your so-called optimising.
"Inbound marketing" is just yet another stupid "buzz phrase" invented to confuse people and keep them under the impression that SEO is some kind of "black magic", and you need to study with the "Zen Masters" to understand what it all means, and quite frankly THAT is a complete and total load of bullshit!
The more you try and follow these "latest SEO technique", the less your website URLs are going to be 'optimal', because for every 'trick' that 'works' there are several highly experienced, highly qualified Google engineers working to stop it 'working'.
Just forget these stupid and pointless tricks and provide search engines with EXACTLY what the REALLY want from your websites.
