SEO Mistakes & Tactics to Avoid

Three separate categories get mixed together under "SEO mistakes": accidents that cost you traffic, advice that used to be true and no longer is, and deliberate manipulation that carries real risk. They need different responses, so this lesson keeps them apart.

Every one of these is invisible from the front end — the site looks perfectly fine to a visitor. They are found by checking, which is what the next lesson is about.

SEO writing has a long tail of material that was accurate years ago and is repeated indefinitely. Things you may still be told to do, which no longer help:

• Meta keywords tag. Long ignored by major search engines. Filling it in does nothing at all.
• Targeting an exact keyword density. There is no such target, and writing to hit one produces worse text.
• Submitting your site to hundreds of directories. A tactic from an earlier web; now, at best, ignored.
• Exact-match domains. Buying bestcheaplaptopskolkata.com does not confer ranking on its own.
• Article spinning. Rewriting one article into many near-duplicates. Detected easily and treated as spam.
• Chasing a single "SEO score" from a tool. These are heuristics invented by tool vendors, not measurements of anything a search engine calculates.

These are violations of search engine guidelines, not grey areas:

• Hidden text — keywords in white on a white background, positioned off-screen, or set to zero opacity.
• Cloaking — showing search engines different content from what visitors see.
• Doorway pages — many near-identical pages built to capture variations of a search, all funnelling to the same place.
• Buying links that pass ranking credit, without disclosure.
• Scraped content — republishing other sites’ material as your own.
• Mass-generated content produced at scale with no editing, review, or added value.

The consequence can be an algorithmic devaluation or a manual penalty. Recovering from either means finding and removing everything involved, then requesting review, and it can take a long time. The trade is a short-term gain against a durable risk.

Before doing anything for SEO reasons, ask: would I still do this if search engines did not exist?

Writing a clear title, structuring a page well, compressing images, making a site fast, linking to a related page where it helps — all of these pass. They are good for visitors, and the search benefit follows from that.

Repeating a phrase twelve times, generating pages nobody would read, buying links, hiding text — none of them pass. They exist only to influence a machine, and that is precisely the category search engines spend their engineering effort detecting.
