Website saturation and popularity, or how much presence a website has on search engines, can be analyzed through the number of pages of the site that are indexed by search engines (saturation) and how many backlinks the site has (popularity). It requires pages to contain keywords people are looking for and ensure that they rank high enough in search engine rankings. Most search engines include some form of link popularity in their ranking algorithms. The following are major tools measuring various aspects of saturation and link popularity: Link Popularity, Top 10 Google Analysis, and Marketleap's Link Popularity and Search Engine Saturation.

Google doesn't always include a whole paragraph of text in the Featured Snippet. If you add "Step 1," "Step 2," "Step 3," etc. to the start of each HTML heading within your content (for example, within your H2 tags), Google will sometimes just list out your headings within the Featured Snippet. I've started to see this happen more and more in keywords beginning with "how to".
Probably the most well-known Integrated Vertical Search is  Google’s “Universal Search” –  although all of the major search engines have now adopted similar search formats. This is the practice of incorporating different types of results in the Search Engine Results Pages (SERPs), such as news releases, images, videos, etc., depending on the query.  This was a game changer for SEO when it was first introduced – it became necessary to create and optimize many different types of content because they all show up on SERPs. The term for this comprehensive approach is referred to as Digital Asset Optimization (DAO).

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.
Very interesting video! In my case I am faced with the problem that my company supplies tools throughout my country, but I see that we have only a very good local SEO positioning, I do not know how to tell Google that my company is interested in appearing in the results of the whole country, not only in my neighborhood :-( !! ... sorry for my poor English.

Many page owners think that organic reach (the number of unique individuals who see your post pop up in their news feeds) is enough to make an impact. This was true in the first few years of Facebook but is no longer the case. Facebook, and many other social media networks is truly a pay-to-play network. Facebook, Twitter, Instagram, and LinkedIn are all on algorithmic feeds, meaning posts are shown to the user based on past behavior and preferences instead of in chronological order. Organic posts from your Facebook page only reach about 2% of your followers, and that number is dropping. Facebook recently announced that, in order to correct a past metrics error, it is changing the way it reports viewable impressions, and organic reach will be 20% lower on average when this change takes effect.
Though a long break is never suggested, there are times that money can be shifted and put towards other resources for a short time. A good example would be an online retailer. In the couple of weeks leading up to the Christmas holidays, you are unlikely to get more organic placement than you already have. Besides, the window of opportunity for shipping gifts to arrive before Christmas is ending, and you are heading into a slow season.
