Content is one of the 3 main Google ranking factors. As a matter of fact, having a blog can help you get your content indexed faster. An active blog – relying on qualitative and insightful content, and backed by authoritative links – will help you improve your rankings and thus your organic traffic. Also, long-form copies (above 1200 words) tend to rank higher and be crawled more often.
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 for a very famous example.
Here users can find what services are around, or where to buy a particular product. Meanwhile, local searches provide instant information and specific data on customers’ needs, such as a telephone numbers, the address of a company or its public opening hours. Also, do not forget your smartphone as a tool to find information anywhere. 77% of the users of these devices use them to find information preferably in their immediate environment.
That’s not to say that there isn’t the same kind of competitive intelligence where SEO is concerned. In fact, I’m a big fan of analyzing your competitor’s SEO landscape. You can check what keywords they’re targeting and their sources of referral traffic to strengthen your strategy. But the bottom line is this: Your competitors can’t steal your content. The experience that you provide to users is unique to you.The more organic traffic you have, the more currency you have in the online space.
For instance, before launching a new product or service, a business can create a simple landing page to gather feedback from the target audience. Or it can run a survey asking a bunch of targeted questions. Or it can even go a step further and create a minimum viable product to see how the target users are interacting with it. With a bit of creativity, PPC ads can help gather real-time feedback that can be used to improve the end product, or idea.
Remember when you used to rely solely on search engines for traffic? Remember when you worked on SEO and lived and died by your placement in Google? Were you #1? Assured success. Well, okay, maybe not assured. Success only came if the keywords were relevant to your site users, but it was the only real roadmap to generating site traffic and revenue.
