Algorithm
Algorithm is the rule set a software system uses to decide what happens, what surfaces, or what gets ranked - Google’s search algorithm, Instagram’s feed algorithm, your bank’s fraud-detection algorithm. The word’s been so flattened by marketing-speak that it’s almost lost meaning, but the underlying idea is simple: defined inputs, defined logic, output you can measure.
For people in content and marketing, “the algorithm” usually means one of three things: the search algorithm Google uses to rank pages, the recommendation algorithm a social platform uses to pick what’s in someone’s feed, or the ad algorithm that decides who sees what.
Why the word does so much work in marketing
Because every channel that matters runs on one. SEO is reverse-engineering Google’s algorithm. Social organic is reverse-engineering each platform’s. Paid ads is bidding into an auction where the algorithm decides which ad the user sees and what you pay for the privilege.
The job of a content marketer is to understand each algorithm well enough to feed it what it wants without doing anything stupid that gets the page or account penalised. You’re not gaming it - you’re aligning to its goal so it’ll show your stuff.
What the major content algorithms reward
Different platforms, similar principles:
Google’s algorithm rewards content that matches search intent, demonstrates expertise on the topic, has earned credibility from other reputable sites (backlinks), and gets cited by users as the answer to similar questions.
Social feed algorithms (Instagram, TikTok, LinkedIn) reward content that holds attention - watch time, saves, shares, comments. Likes alone barely register now. The platforms care whether the post made the user stay on the platform longer.
Ad algorithms reward predicted relevance - your ad gets shown when the platform thinks the click-through and conversion outcome will be high enough to justify outbidding everyone else for the slot.
The tactical mistake people make
Treating the algorithm as the audience. The algorithm is the gatekeeper, not the customer. Content engineered to please the algorithm but bore the actual reader will surface, get clicked on, get judged by user behaviour, and quietly demoted. The algorithm is downstream of whether real humans engage.
The longer-term play: make stuff humans demonstrably want, and the algorithm will do its job. Game theory dressed up in machine learning still rewards the underlying signal.
An example
A B2B SaaS publishes two articles in the same week. The first targets a $4 CPC keyword with classic SEO hygiene: 2,400 words, H2/H3 structure, schema, internal links, FAQ section. The second is a 900-word strong-opinion post on a niche industry debate, ignoring keyword targeting entirely.
Eight weeks later: the SEO-optimised piece ranks #6 for its target keyword, pulls 280 monthly visitors, two trial signups. The opinion piece ranks for nothing in particular but gets shared on LinkedIn 340 times, drives 4,100 sessions that week from social, and converts 31 trials.
Same publisher, same week, same brand. Different algorithms, different shapes of content. The lesson isn’t “ignore SEO” - it’s that “the algorithm” isn’t one thing, and your content strategy should know which one each piece is being judged by.
Every update to search and ranking algorithms in the last five years has rewarded the same underlying thing: content that sounds like it was written by a person who actually understood the topic. We built Penfriend because that’s harder to produce at scale, not easier - and the tools that produce it badly are easier to catch now than ever.
