If you get an "Action Against Links" notice - there is no plea you can send. Your site or some pages of it - would basically have a lot of rankings. To fix things you need to fix links and any other on-page and other issues and wait for the re-crawl to happen. Since the Penguin algorithm is not real-time... you will see ranking gains faster and you do not have to wait for a data-refresh to happen to see any benefits of your link purge or SEO fixes.
Just because a phrase didn’t appear in either of these tools doesn’t mean there is no demand for it. There are other ways to confirm that someone is interested in this topic. And for the blog posts and articles that target the informational keyphrases, we aren’t necessarily looking for huge demand. Any visibility in search can make a big difference in the performance of a post.
External duplicate content is when you copy-paste content from other websites. Usually without placing a link to the original source or using canonical attribute. Google dislikes such content for one simple reason. It doesn’t add any value to end users and the Internet in general. If you have to choose between copying articles from other sources or not having any at all, I’d suggest you choose the latter.
In Chapter 2, we learned about SERP features. That background is going to help us understand how searchers want to consume information for a particular keyword. The format in which Google chooses to display search results depends on intent, and every query has a unique one. Google describes these intents in their Quality Rater Guidelines as either “know” (find information), “do” (accomplish a goal), “website” (find a specific website), or “visit-in-person” (visit a local business).
However, this does not mean you cannot topple them. It just takes more of an effort in terms of content as your page has to build the trust. That is why you will see the "Google dance" happening for fresh content from a site that is not yet trusted or is not very authoritative. Google gives your page a chance and measures user click-throughs when it pushes you to certain spots in the SERPs and then measures user engagement levels when the traffic hit your site through those positions in the SERPs.
