That's nice Yukinari but I would like you to tell others to chill the fuck out, stop crying etc. if all YOUR sites had tanked, hence a huge amount of income lost, as many people around this forum have over the past couple days. You as anyone else should know that even if you do everything "right", all it takes is one major update to fuck you. I carry on and work, yes, as it's too early to say what will happen yet, but there is no such thing as a "true" SEO. So many people call themselves "SEO specialists" and "SEO consultants" when they are just fiverr brokers in reality or a bunch of indians manually spamming links all day for $2 an hour. More than anything I am a webspammer, so this update is like the coming of the antichrist. I haven't cried yet but if more of my sites tank then crying will be well justified and anyone who tells us not to have a good cry has obviously dodged the bullet (for now). Much like people who were getting links from BMR and other blog networks thought they were relatively "white hat".
You say there is no such thing as a true SEO, yet you talk about Fiverr brokers and poor quality outsourcers falsely parading themselves as SEO specialists....right there you just made a distinction yourself about what real SEOers are and are not.
Those that use cheap outsourcing or places like Fiverr as part of their long term SEO strategy are more often than not nothing more than inexperienced people hoping to make a quick buck. Those that know the "ins and outs" of SEO know that Google specifically hates paid links and of course they also know about paid blog networks, places like Fiverr, automation software etc; especially now since those things are all main stream and massively abused by people that are either too lazy to learn proper link building themselves or think putting up a simple affiliate site and blasting it with a bunch of cheap links they bought from Fiverr will make them cash. It's no wonder Google is starting to crack down on quality, and to be honest, I thought this would happen sooner.
If you are a self-proclaimed webspammer, than you should have expected this day to come far in advance. I honestly have not had any long-term problems with my money sites ranking in Google throughout any updates. Yes, I experience fluctuations in rankings, but that's normal. I'm not saying this to brag or talk down to anyone, I'm saying this because in the end, if you want to rank in Google's organic SERPs, then understanding what they want and giving it too them on your websites is crucial.
And for those saying Bing is the "future" we'll have to wait and see, but as it is now, they are far from it. They have been caught already copying Google's search results, and they pretty much mirror all the changes Google makes to their SERPs because they know Google has a huge advantage and hold on the search market.
The only way they would have a chance at beating Google out would be to grow their brand larger than Google which is going to be a hell of a task since they currently don't have anything to offer that would make them better than Google in the long run.
