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.

Let’s say, for example, that you run a construction business that helps with home repairs after natural disasters and you want to advertise that service. The official term for the service is “fire restoration,” but keyword research may indicate that customers in your area search instead for “fire repair” or “repair fire damage to house.” By not optimizing for these two keywords, you’ll lose out on a lot of traffic and potential customers, even if “fire restoration” is technically more correct.
The most reliable way to increase search engine traffic is to create great content that your audience is looking for. For example, if you’re a pest control company, you may write a bunch of quality blog posts on getting rid of pests. The idea is to educate your prospects and move them towards buying from you. This is exactly where SEO intersects with content marketing.
Paid marketing, on the other hand, allows business to target, reach, engage, and convert their audiences quickly and directly. Instead of waiting – or hoping – for someone to find your blog post in organic search or on social, paid marketing has you “pushing” content – mainly in the form of ads – directly to your target audiences. As such, it’s much more sales-forward and focused on driving specific actions, like making a purchase or attending a webinar. Here’s an example of this in action:
While organic search may drive many times more traffic to your site than paid search, you can use this report to see the quality of traffic driven by each method. For example, if you look atSite Usage statistics, you may see that organic search delivers 20 to 30 times the number of visitors, but those visitors view only half as many pages and have twice the bounce rate. And when you look at Ecommerce statistics, you may see that visitors from paid search have a much higher rate of transactions, along with a higher average value per transaction, and a higher dollar value per visit. If you find that your visitors who arrive via paid search represent a significantly higher value customer, that may be an argument to invest more in paid search.
Here’s the thing. Your web visitors aren’t homogeneous. This means that everyone accesses your site by taking a different path. You may not even be able to track that first point of contact for every visitor. Maybe they first heard of you offline. But in most cases, you can track that first touch point. The benefit? You can meet your potential customers exactly where they are.
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.
All your content, social media, brand, and other online assets that you develop in that process are there to stay. And they keep going up in value as time goes by. Even if you stopped investing in organic search, these assets would still be working for your business. You’d get traffic because you’ve built an ecosystem that fuels itself. Now imagine that you’re generating traffic and you’re paying little to no money for it. Your cost per organic visitor will decrease by many factors as your return increases. Bear in mind that this is a cumulative effect that happens over time. Still, it’s a fantastic position to be in.
For our client: We monitored everything on a daily basis. If something came up, which needed to be fixed, we were quick to implement it with the development team at the business. We also rolled out numerous campaigns multiple times as they worked effectively the first time around in generating significant traffic so it was second nature to do the same thing twice.

SEM is the wider discipline that incorporates SEO. SEM includes both paid search results (using tools like Google Adwords or Bing Ads, formerly known as Microsoft adCenter) and organic search results (SEO). SEM uses paid advertising with AdWords or Bing Ads, pay per click (particularly beneficial for local providers as it enables potential consumers to contact a company directly with one click), article submissions, advertising and making sure SEO has been done. A keyword analysis is performed for both SEO and SEM, but not necessarily at the same time. SEM and SEO both need to be monitored and updated frequently to reflect evolving best practices.

Organic Search: Organic search results are the listings of Web pages returned by the search engine’s algorithms that closely match the search string of keywords. Marketers use SEO and content assets to get high search engine rankings. The goal is to be on the first page and then move into the top three rankings for specific keywords. That’s because the advantages of organic search are dependent on visibility. The higher the ranking the more pronounced the advantages. They all but disappear if your listing is not on the first page.
Check out the average CPC for some top industries. These are the costs of one click. Mind you, that’s a click that is not guaranteed to convert a customer. With paid campaigns, you have to keep optimizing and testing the ad creative to lower your CPC and increase your CTR. You can imagine that it takes a massive budget to even set a paid campaign in motion. And it requires just as much to keep maintaining it.
The Google, Yahoo!, and Bing search engines insert advertising on their search results pages. The ads are designed to look similar to the search results, though different enough for readers to distinguish between ads and actual results. This is done with various differences in background, text, link colors, and/or placement on the page. However, the appearance of ads on all major search engines is so similar to genuine search results that a majority of search engine users cannot effectively distinguish between the two.[1]
