Zombie SEO Tactics That Refuse to Die (Meta Keywords, Exact-Match Domains, and More)

Every few months, an audit lands on someone's desk recommending something that stopped working years ago. Here are the zombies worth putting to rest.

TL;DR: Meta keywords, exact-match domains, mass directory submissions, hidden keyword text, "ideal" word counts, and a handful of other relics still circulate as SEO advice. Some are harmless time-wasters; others violate Google's spam policies. If a recommendation is pitched as a secret trick rather than documented practice, check it before you spend on it.

1. The meta keywords tag

Google has said for years that it doesn't use the meta keywords tag for web search ranking. Filling it in does nothing for Google, and may only tell competitors which phrases you're targeting.

2. Exact-match domains

Buying a domain that matches your target phrase doesn't confer a special ranking advantage. Brand and content do the work. A forgettable keyword domain can even weaken your brand.

3. Hidden text and keyword-stuffed footers

White text on a white background, tiny keyword blocks, and stuffed footers are named in Google's spam policies. They also don't help people. Remove them.

4. Mass directory and article-site submissions

Submitting to hundreds of low-quality directories adds nothing and can look manipulative. A few relevant, reputable listings are fine. A blast is not.

5. "Ideal" word counts

There's no minimum or maximum length that ranks. Pages should be as long as it takes to answer the query well. Padding to hit a number is the opposite of helpful. See why your content isn't ranking.

6. "Only one H1 per page"

Clear heading structure helps readers and systems, but multiple H1s aren't a ranking penalty. Focus on logical headings, not arbitrary rules.

7. Re-dating pages to look fresh

Changing a publish date without changing the content doesn't make a page more relevant. Real updates (new data, corrected facts, better answers) do.

8. Social shares as a direct ranking factor

Google has said social signals aren't direct ranking factors. Social can still bring traffic and mentions that help in other ways, so it isn't useless. It just isn't a shortcut.

Why zombies keep coming back

• Old articles still rank and keep getting shared.
• Plugins and checklists haven't been updated.
• Sellers benefit from a long to-do list.
• Some of these tactics once worked, partially or briefly.

How to check any SEO claim

1. Look for it in Google Search Central documentation.
2. Ask what evidence supports it and whether that evidence is current.
3. Run a small test if the stakes are low.
4. Ask who profits from you believing it. Our guide to SEO agency red flags goes deeper on this.

What to do instead

Invest in clear titles and headings, original content, sound technical foundations, and real reputation, the things that keep working. Our myth roundup lists the other big ones.

FAQ

Is the meta description a ranking factor? Not directly. A good description can improve click-through, but Google may also rewrite it.

Do keywords in URLs help? Slightly, mostly by clarifying the topic to users. Don't expect a boost from stuffing them.

Are nofollow tricks like PageRank sculpting useful? No. They're a relic of an earlier approach and rarely worth the complexity.

Could an old tactic on my site hurt me? Spammy tactics like hidden text can. Clean them up, and review inherited work from previous agencies.
