Comment on SEO 2017 by SEO Dave.
It’s 80+ pages of info/SEO data I’ve not gone through completely yet (always makes for an interesting read), so not writing this comment to discuss what were/are the most important Google SEO ranking factors for 2014 and probably important in 2015, but how these sorts of SEO data results are generally misinterpreted by non scientists.
I don’t blame SearchMetrics for the SEO research, it’s generally very good SEO research and they warn users this is correlation NOT causation, though I find this distinction is lost on most SEO’s and webmasters.
SEO Correlation vs SEO Causation
Every morning a cockerel crows on the farm and the Sunrises.
We all know a cockerel crowing does not cause the Sun to rise, this is correlation not causation, yet some in the past will have believed the cockerel crowing caused the Sunrise.
Without scientific study you might assume the Sun rising per se would CAUSE the cockerel to crow (this would be causation, the light from the Sun rising causes the action), but an article in Cell (science magazine) indicates cockerels have an internal biological clock and will crow without seeing the dawn (they still crow in a dark room). So even the crow of the cockerel isn’t caused by the Sun rise per se, there’s clearly a link: the biological clock is in sync with the Sun rise, but from the info we have we can’t be sure it’s actually the Sunrise that’s the direct cause.
Never assume because A occurs when B is present, B causes A.
This is the basic scientific process and an essential tool when analysing SEO data.
I was looking through the WordPress support forums recently and read a support question how to organise their title tag and meta tags in this format code wise:
Meta Description Tag
Meta Keywords Tag
The person who asked the question had researched a SERP they wanted for their website and found the top websites for that SERP all had the above meta tags format.
This is again SEO correlation not SEO causation. Google ignores the meta keywords tag completely and doesn’t use the meta description tag as a ranking factor and though where some content is located in the code is a ranking factor, the above is not a ranking factor.
Humans have evolved to search for patterns, we are amazing at finding real patterns, but it leaves us open to finding patterns where none exist. Examples of finding patterns where none exists include:
Lucky Trinkets : Rabbits foot, lucky horse shoe, lucky item of clothing.
Religion : We pray and sometimes good stuff happens.
Astrology : Yep, the alignment of the stars and planets as seen from Earth control our destiny!
Faith Healing : Placebo effect/coincidence.
At my core I’m a scientist and if a result can’t be repeated under scientific conditions it’s not been proved and shouldn’t be be relied upon as a fact.
Looking through the SEO Ranking Factors and Rank Correlations 2014 data there are so many data points that can easily be explained as SEO correlation not SEO causation.
Social media for example, over recent years many in the SEO industry have moved to believe social media metrics are a huge SEO ranking factor. Facebook likes, Google+ shares, Twitter mentions etc… and a whole industry has developed selling Facebook likes etc…
This is not to say social media metrics are not ranking factors, but the way webmasters interpret the data isn’t scientific and can not be relied upon. Google might completely ignore Facebook likes, Twitter mentions… the SEO data available doesn’t indicate either way.
The SEO correlation is when looking at webpages that rank high in Google there’s a tendency for those pages also to have a strong social media footprint (lots of Twitter mentions, Google+ shares, Facebook likes…
The SEO question, is the strong social media footprint a cause of high Google rankings or an artifact of high Google rankings?
It’s not easy to scientifically test this.
How do you setup an SEO test where you generate webpages with a strong social media footprint without also generating other known SEO ranking signals like backlinks?
Let’s say you have a network of social media users willing to like and share your content for an SEO test, once they start liking and sharing the content their followers etc… will see the content and start liking and sharing as well and some will add backlinks from blogs etc… and we know backlinks are very important to Google rankings: are SEO ranking increases due to the social media footprint or the new backlinks and additional visitors or other factors?
It’s practically impossible to test possible social media ranking factors independently of other factors. Being popular on social media sites will increase other important SEO ranking factors.
We have two possible conclusions.
A strong social media footprint results in better Google rankings.
Better Google rankings results in a strong social media footprint.
With the former social media activity is a (major) ranking factor.
With the latter social media activity isn’t a (major) ranking factor, it’s an artifact of higher traffic.
Current SEO data doesn’t provide a clear answer.
All we really know is popular websites tend to have a strong social media footprint, but that’s not universally true. This website has a weak social media footprint and for a website that’s under one year old is ranking high in Google. This doesn’t prove social media metrics per se aren’t important at all to Google, suggests if social media is a ranking factor, other SEO factors are as or more important. I wouldn’t conclude from this one data set that social media factors aren’t important.
You can see the difficulty in determining what is and isn’t important SEO wise. For this reason my SEO approach tends to be remove as many factors I know causes SEO damage (like rel=”nofollow” links) and work on factors that I either know for sure have SEO value (I know backlinks are important) and work on factors that won’t cause harm and might help.
There’s indications Google in 2015 will consider usability as a more important SEO factor, making a website better for users doesn’t damage a site, therefore it’s a good factor to work on even if Google doesn’t consider it that important.
On the other hand I know Google completely ignores the meta keywords tag, so spending time optimizing the meta keywords tags is a complete waste of time: adds nothing for users, adds nothing for Google and since adding a meta tag that doesn’t achieve anything is a waste of resources it could be argued is SEO damaging.
