A disadvantage of digital advertising is the large amount of competing goods and services that are also using the same digital marketing strategies. For example, when someone searches for a specific product from a specific company online, if a similar company uses targeted advertising online then they can appear on the customer's home page, allowing the customer to look at alternative options for a cheaper price or better quality of the same product or a quicker way of finding what they want online.
Optimization techniques are highly tuned to the dominant search engines in the target market. The search engines' market shares vary from market to market, as does competition. In 2003, Danny Sullivan stated that Google represented about 75% of all searches. In markets outside the United States, Google's share is often larger, and Google remains the dominant search engine worldwide as of 2007. As of 2006, Google had an 85–90% market share in Germany. While there were hundreds of SEO firms in the US at that time, there were only about five in Germany. As of June 2008, the market share of Google in the UK was close to 90% according to Hitwise. That market share is achieved in a number of countries.
Sharpe says that you shouldn't dive into internet marketing until you decide on a niche and figure out what you're passionate about. Do you want to join the make-money-online (MMO) niche? Or do you want to engage in another niche? For example, you could sell products or online courses about blogging or search engine optimization or anything else for that matter. Keep in mind that whatever you're selling, whatever niche you're in, that you need to embed yourself there deeply.
But how do you get quoted in news articles?

3) Some people don’t believe things have changed. In fact, if things really changed substantially a year ago, you’d think a few of the advanced SEOs out there would have noticed this and talked about it. But nada. There are lots of reasons why the change could have happened and not been spotted. Sculpting might really have been a second or third order factor, as Matt calls it — not helping things as much as some have assumed. SEOs that spotted it might have stayed quiet. Or, it didn’t change — and still hasn’t changed — and sculpting does work even better than Google thought, so it wants to put out a message that it doesn’t, in hopes of putting the genie back in the bottle. That’s probably the major conspiracy theory out there.
As for the use of nofollow as a way to keep pages that shouldn’t be indexed out of Google (as with your feed example) is terrible advice. Your use of it on your feed link does nothing. If anyone links to your feed without nofollow, then it’s going to get indexed. Things that shouldn’t be indexed need to use either robots.txt or meta robots blocking. Nofollow on links to those items isn’t a solution.
A generalization of PageRank for the case of ranking two interacting groups of objects was described in  In applications it may be necessary to model systems having objects of two kinds where a weighted relation is defined on object pairs. This leads to considering bipartite graphs. For such graphs two related positive or nonnegative irreducible matrices corresponding to vertex partition sets can be defined. One can compute rankings of objects in both groups as eigenvectors corresponding to the maximal positive eigenvalues of these matrices. Normed eigenvectors exist and are unique by the Perron or Perron-Frobenius theorem. Example: consumers and products. The relation weight is the product consumption rate.
Just do a quick Google search. If you're monitoring to see if a link you built is indexed, or just want to find other areas where you've been mentioned or linked, do a quick search with your company brand name, your web URL or other terms you're following. I've seen plenty of backlinks indexed by the search engine that never showed up in my search console account.
