The contest for the top spots in SERPs is constantly upended by adjustments made by the search engines themselves to the unspoken rules and metrics they use to determine which URLs should be placed above the competition. Some methods that were previously relied on by web designers and marketers to at least match their competitors are steadily losing the impact they should have on websites' rankings. This is primarily because search engines, most prominently Google, seek to create an online environment that only ever rewards the most trustworthy and authoritative results for a given search query with a solid flow of traffic.
Google keeps its ranking algorithms hidden so that web designers do not prioritize technically satisfying them at the potential expense of providing organically strong content for users who would prefer the most thoughtful content possible. Even so, there are times when the world's web designers steadily latch onto established methods of "organically" getting ahead and end up unexpectedly turning those methods into routines that can be approached with a cynical mindset.
Writing guest posts on other websites' blogs is an example of an SEO-friendly step that everyone used to take because it was an easy way to direct viable link juice to one's own site. However, backlinks are conceptually regarded as important by the ranking metrics only because they supposedly represent instances of a website's quality eliciting attention from across the Internet through the spread of positive word of mouth. Google is becoming more adept at recognizing guest posts as, essentially, methods undertaken directly by the site's own webmaster to fabricate this representation of spreading awareness.
There is still some value to be had in going onto another website's community section and writing blog content that effectively stands in as very subtle and well-disguised self-promotion. However, the fact that this value has diminished in recent years is intended to stimulate web authors' efforts to focus purely on the substance of their own sites. Any natural occurrences of external websites voluntarily mentioning the site on the basis of this substance should end up affecting the site's SEO more positively.
