Ten SEO myths that still will not die

Fibvo editorial · 5 December 2021 · 6 min read

SEO advice has a long half-life problem: tactics that were once genuinely effective, or misconceptions that were never quite true, continue circulating years after they stopped being useful, or were ever accurate at all. Here are ten that persist despite clear evidence and guidance to the contrary.

Myth one: keyword density has an ideal percentage

There is no magic keyword density percentage, and never reliably was — writing naturally and covering a topic thoroughly, as covered in our Hummingbird explainer, has outperformed keyword density formulas for over a decade.

Myth two: meta keywords tag still matters

Google has not used the meta keywords tag as a ranking signal since 2009 — including it is harmless but provides zero SEO value.

Myth three: more backlinks always means better rankings

As covered in our backlink quality versus quantity guide, a handful of genuinely relevant, authoritative links consistently outperforms a large volume of low-quality ones.

Myth four: duplicate content triggers an automatic penalty

As covered in our duplicate content guide, there is no direct penalty — the real risk is diluted ranking signals, a meaningfully different mechanism.

Most SEO myths share a common origin: a genuinely true observation from a decade ago, repeated long after the underlying algorithm moved on.

Myth five: Google Ads spend improves organic rankings

Paid and organic search results operate through entirely separate systems — spending on Google Ads has no direct influence on organic ranking whatsoever.

Myth six: content needs to be a specific word count to rank

There is no universal ideal word count — content length should match what genuinely, thoroughly answers the topic and searcher intent, not an arbitrary number.

Myth seven: a sitemap submission guarantees indexing

As covered in our XML sitemap guide, a sitemap only aids discovery — indexing still depends on Google's independent quality and relevance assessment of each page.

Myth eight: HTTPS alone will significantly boost rankings

As covered in our HTTPS ranking signal guide, it is a lightweight signal, not a significant standalone ranking boost, particularly given near-universal adoption across the web.

Myth nine: bounce rate is a direct Google ranking factor

Google has repeatedly denied using bounce rate directly as a ranking signal — engagement metrics may correlate with quality indirectly, but there is no direct causal mechanism as often claimed.

Myth ten: AI-generated content is automatically penalised

As covered in our scaled content abuse explainer, the concern is mass-produced, low-value content regardless of the tool used to produce it, not the use of AI assistance itself.
