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.
I would like to talk about a case study for a large start up I worked on for over eight months in the Australian and US market. This client originally came to the company with the typical link building and SEO problems. They had been using a SEO company that had an extensive link network and was using less than impressive SEO tactics and methodologies over the last 12 months. The company was also losing considerable revenue as a direct result of this low quality SEO work. So, I had to scramble and develop a revival strategy for this client.
The first is that you look at who are your current customers, who are your prospects, what groups are they in, and join those same groups if they’re relevant and not too title specific to a marketer or a different field that you’re not in. But really starting with the folks that you already are working with and using them to figure out which groups are most relevant. This is also especially important because I think it was about a year ago, LinkedIn now made all the groups private. So you can’t go in and look at what’s going on in the group. And it’s really hard to know which ones are the best ones to join just by doing simple searches on say the title of the group. So, start with the folks that you know.
Paid Search (PPC): Paid search results are advertisements. A business pays to have their ads displayed when users do a search containing specific keywords. The ads are typically displayed above and to the right of organic search results. The exact placement of the ads is determined by both a bidding process and quality score. The advantages and drawbacks of paid search are often the opposite of organic listings.
While organic search has the advantage of being free and can be influenced by your website content, it is limited to the number of people searching for your business or the products and services you offer. Paid search advertising allows you to reach a broader target audience which has more potential customers who may not be aware of your business, all while providing you full control over your messaging and costs.
BrightEdge research supports that a blended approach is best for delivering high performing content. Not only will combining organic and paid search increase website traffic, but it will offer a bigger return on the investment. Take Retail, Technology and Hospitality industries, for example — organic and paid search combined make up more than two-thirds of their total revenue.
