Google doesn't rank pages on one factor — it's a weighted combination of signals, and the weighting shifts over time. You don't need to memorize all of them, but understanding the categories helps explain why a technically perfect page can still lose to a "worse" one, and vice versa.
Relevance comes first, but it's a floor, not a ranking factor by itself
A page has to actually be about what someone searched for — that's table stakes, not a differentiator. Everyone ranking on page one for a competitive term already cleared this bar. What separates position 1 from position 8 happens after relevance is established.
Content quality and depth
Google's own guidance is explicit that content written primarily to rank, rather than to genuinely help a reader, gets filtered down over time. In practice this means: does the page answer the actual question completely, with real specifics, or does it circle the topic in generalities? Thin, templated content is exactly what this factor penalizes.
Backlinks — still a real signal, still hard to fake
Links from other relevant, reputable sites remain one of the strongest authority signals, because they're the hardest to manufacture at scale without it being obvious. A handful of genuine local links — a chamber of commerce, a local news mention, an industry directory — outweigh a large batch of low-quality, obviously-purchased links.
Page experience: speed, mobile, and stability
Core Web Vitals — how fast a page loads, how quickly it becomes interactive, and whether elements jump around as it loads — are a direct, measurable ranking input. This is also the factor most small business sites quietly fail, usually because of a plugin-heavy CMS rather than anything content-related.
For local businesses specifically: proximity and profile signals
For any search with local intent, your Google Business Profile completeness, review count and recency, and citation consistency across directories carry as much weight as the content on your actual website — sometimes more, for map-pack results specifically.
E-E-A-T: experience, expertise, authority, trust
Google's quality guidelines ask its human evaluators to weigh whether content demonstrates real experience and expertise, and whether the site and author are established and trustworthy. A named, credentialed author with a real bio and history outranks anonymous content, all else equal — which is part of why we put a real author byline on every post on this site.
The practical version
You can't game any one of these in isolation for long. What holds up: content that actually answers the question in depth, a genuinely fast site, real backlinks earned rather than bought, and (for local businesses) an active Google Business Profile. Everything else is a smaller multiplier on top of those fundamentals.
