When all is said and done, aim of algo updates at this time and age is to increase Google revenue.
Be in denial, if this makes you feel better.
Out of sight, out of mind...
Recently, many threads have turned to general editorial commentary about Google and their business practices - no matter what the opening topic. As the Charter explains, this is making it difficult to have discussions that are of value for those working with hands-on SEO....
Fact is, every algorithm change is good for some people and not so good for others.
Information is not filtered like this without someone on top with deep pockets paying for it to be so.
I wonder who'd have pockets deep enough to convince a self-sustainable 750 billion dollar company to push their agenda, putting the company.
how an algo update (that by definition shuffles rankings) could be good for "Google alone"
We see a lot of wild and unsubstantiated claims (or "general editorial commentary") regarding Google (and other things, occasionally), usually from the same people, and usually they don't stand up very well to some light prodding.
we certainly are NOT competing against Google at all in the SERPS.
Unless, of course, you're suggesting that Google tweaks the algorithm to favor its own properties.
Absolutely correct they are! Not every algo update but enough of them. Open your eyes.
