SEO keywords are the words and phrases people actually type into Google when they're looking for something you offer. Keyword research is the process of finding those exact phrases, then using them — naturally — in your titles, headings, and page copy, so search engines understand what the page is about and match it to the right searches. Done well, it's less about tricking an algorithm and more about describing your page the way your customer already thinks about it.
What actually counts as a keyword
A keyword isn't always a single word. "Shoes" is a keyword. So is "best running shoes for flat feet under ₹5000." Both are valid — they just serve different jobs, at different points in someone's search.
Short-tail vs long-tail keywords
Short-tail keywords are broad — one or two words, high search volume, and brutally competitive ("marketing agency," "jewellery online"). Long-tail keywords are longer and more specific ("digital marketing agency for jewellery brands in Ahmedabad"). They get searched less often, but the person searching knows exactly what they want — which usually means they're closer to buying, and you're competing against far fewer pages to reach them.
Search intent is the part most people skip
Before targeting a keyword, ask what the searcher actually wants:
- Informational — "what is SEO" (they want to learn)
- Commercial — "best SEO tools 2026" (they're comparing options)
- Transactional — "hire SEO freelancer" (they're ready to act)
- Navigational — "Google Search Console login" (they want a specific site)
Writing a product page for an informational keyword — or a blog post for a transactional one — is one of the most common reasons content doesn't rank, even when the keyword itself was a good pick.
Where to find keywords, for free
- Start typing your topic into Google and read the autosuggest list — those are real, common phrases
- Scroll to "People also ask" and "Related searches" at the bottom of the results page
- Check Google Search Console on a site you already run — it shows the exact queries people used to find you
- Read a competitor's page and note the phrases they repeat in headings
You don't need a paid tool to start. You need ten minutes on Google and a notes app.
Where to place them once you have them
Keyword placement matters more than keyword quantity. Put your primary keyword in the title tag, the H1, and naturally within the first 100 words. Use it once or twice more across the page's subheadings, in the URL if possible, and in an image's alt text where it genuinely describes the image. Everywhere else, write for the person reading — not the crawler.
The mistake that undoes all of it
Keyword stuffing — repeating a phrase unnaturally, over and over — reads badly to people and gets discounted by search engines anyway. The fix is simple: write the sentence you'd actually say out loud, then check whether the keyword fits in naturally. If it doesn't, use a close variation instead of forcing it.
