What you are in fact talking about, are Google's death stars like the Shopping box, Knowledge Graph etc. It's fully understandable why many SEOs can't stand them 'cause whole categories of websites (price comparison platforms, for instance) have already fallen victim of such death stars, and there will be certainly numerous other portals, which will lose almost all of their traffic in the near future. Despite your (quite good) suggestions on how to circumvent such an issue, the situation for such an endangered portal can be hopeless when it's its whole business model, which a new Google feature makes obsolete. See geizhals.at for a very famous example.
Google is currently been inundated with reconsideration requests from webmasters all over the world. On public holidays the Search Quality teams do not look at reconsideration requests. See below analysis. From my experience it can take anywhere from 15-30+ days for Google to respond to reconsideration requests; during peak periods it can even take longer.

You can also make sure that you’re not bleeding revenue due to friction somewhere along that path. How does that work? When you focus on organic search traffic, you’re compelled to take the battle to multiple marketing fronts. While SEO outperforms all other channels regarding ROI, it doesn’t always work in isolation. Email marketing, content marketing, social media, and other channels can all serve your SEO strategy. I’ll tell you something about marketers who are truly worth their stuff.

Videos, in general, generate tons of traffic, views, and engagement. Live video is becoming the future of online video marketing, and in this session Alessandra will be sharing her years of experience doing live streaming videos. You will learn how to get started with live videos, how to increase your live video reach, how to get those views to click to your website, and more.
Local SERPs that remove almost all need for a website. Then local SERPs, which have been getting more and more aggressively tuned so that you never need to click the website, and, in fact, Google has made it harder and harder to find the website in both mobile and desktop versions of local searches. So if you search for Thai restaurant and you try and find the website of the Thai restaurant you're interested in, as opposed to just information about them in Google's local pack, that's frustratingly difficult. They are making those more and more aggressive and putting them more forward in the results.
Target all the relevant keywords for your industry. If you don’t actively go after the top keywords in your industry, there’s no way you’ll successfully create these customer touch points. The easy way to find these niche keywords? Use a tool like UberSuggest. Plug your queries into the keyword tool to get some more concrete terms. UberSuggest will give you a list of alphabetized queries. You can then use another tool like Google’s Keyword Planner to determine the competitiveness of these keywords.
To do this, I often align the launch of my content with a couple of guest posts on relevant websites to drive a load of relevant traffic to it, as well as some relevant links. This has a knock-on effect toward the organic amplification of the content and means that you at least have something to show for the content (in terms of ROI) if it doesn't do as well as you expect organically.
Hi , the post is really nice , and it made me think if our current strategy is ok or not , 2 things are important " High quality content strategy " and " Good quality Links " now joining those correctly can pose some real challenges , say if we have n no of content writers who are writing for couple of websites, to be generic let’s consider , 1 writer @ 1 website . We have to write make a content strategy for in-house blog of the website to drive authentic traffic on it and a separate content strategy for grabbing  links from some authentic High PR website i.e. CS should be 2 ways , In-house / Outhouse .
Well, yes and no. Sure, you can get hit with an algorithm change or penalty that destroys all your traffic. However, if you have good people who know what they are doing, this is not likely to happen, and if it does, it is easy (in most cases) to get your visits back. Panda and Penguin are another story, but if you get hit by those it is typically not accidental.
