I thought these people are doing changes to improve the quality of google SERPS so that the readers who search for stuff on google will get better quality sites to read. Matt Cutts or others have tried to share this message time and again that all the Panda or algorithm changes that happen are only to improve the quality of searches.
What I learnt today?
Google got absolutely frustrated and decided to set aside their aim to improve the quality of their SERPS and decided to just go out and target every other website out there that are trying to generate backlinks to improve their website rankings in google. Regardless of their website having good quality/helpful/useful content or not. You got backlinks from any of the methods widely used? You're dead.
What will happen now?
Most of the good quality content that readers are looking for will be gone because SEO is not some secret business. Most people who are webmasters or even own local/global businesses and make websites are aware of SEO(onpage atleast) and many of them also try to build backlinks by commenting on blogs/forums/submitting articles etc. Many of them are not even aware of it that it can hurt them because they just found that these are good ways to share your content, get some links and let google realise the high quality content on their site and rank them.
But google instead of bothering that the site has good content or not will say "HEY! You built backlinks? I am going to Penalise you".
Most good quality content sites created by any of the webmasters will have zero backlinks and zero onpage SEO stuff. Most people who are unaware of SEO might have given up already by now that they never ranked because of no backlinks. I'm VERY certain that even if today you make a site, keep creating high quality content without any backlinks, you will NEVER rank. Never ever rank anywhere close to top. Nobody will find your site.
So what does google want?
God knows. These guys have gone crazy now. They say stick to White Hat Technique. But what is white hat technique? Did google ever share what is the correct way to go about ranking your site? We all know that the BS that just writing good quality content on your site will rank you. No way. If someone makes a new site today, will you ever rank by just writing good stuff on your site and no backlink? Google says the best way to get backlinks is by getting them naturally. Let people link to you themselves. HA!
How many sites out there that even write high quality content will manage to get backlinks "Naturally"? We all know that only good products/something really really useful/helpful is going to get some backlinks naturally OR you write something very controversial. And how many stuff out there which is searched each and everyday is considered THAT useful? What about less useful stuff that you just want to read but you'd almost never link back to it since that is not as important.
One suggestion to Google
Google should think more about maintaining quality SERPS than trying to weed out people who try to get to the top. In the end what counts is if the reader is getting what he wanted by searching something. Weed out sites that are spammy/crappy with content that is not even useful to readers. But don't weed out stuff that people love to read just because they did some backlinking to it.
Low quality links?
Discount them and make sure they don't count towards giving link weight-age. No need to "Penalise them" because that will promote Negative SEO which we already see happening as that will happen MORE and MORE now.
