Keyword Analysis: A Practical SEO Guide
Translated from the Spanish original. Leer en español
Look, if you have a website, a blog, a store or an idea rattling around your head and you don't know what people search for on Google, you are shooting in the dark.
Keyword analysis is not a luxury. It is the damn treasure map.
This isn't just about putting "the best keywords" because you can. It is about understanding what your customer wants before they know it themselves.
It is about knowing whether what you sell is being searched for, how it is searched and whether you can sneak onto their screen before anyone else.
A keyword is not just a word. It is an intent. It is a need. It is someone with their card in hand ready to buy... or a curious person who doesn't even know they need you, but will if you speak to them well.
The only reason you do SEO without this... and you are wasting your time
I'll tell you without anesthesia: if you write without having done a keyword analysis, you are doing decorative SEO. Like those who open a restaurant without knowing whether anyone walks down that street.
Do you want to rank? Then you have to know three things before writing a single line:
- What they search for.
- How many search for it.
- What they expect to find.
Writing without that is like filling up with gas without a car.
Today, every piece of content I launch is born from a real search. Because that makes sure someone is going to read it, and if I do it well, that they will buy from me, follow me, or at least give me their time (which on the internet is pure gold).
What nobody tells you about how to find the best keywords
Here comes the juicy part. It isn't just about looking for "words with lots of searches". Because even the intern knows that. The trick is to find the ones with intent and low competition.
For that you need two things: sniper eyes and tools worth using.
A good keyword is:
- Searched (at least a few dozen a month).
- With clear intent (buy, compare, learn, solve).
- With manageable competition (if the top 10 spots are giant companies... goodbye).
- And if it is long tail, even better: "best cream for oily skin with acne" sells more than "face cream".
Difficulty, volume, intent and money: the combo that rules
Let's put names on the table. These are the 4 factors that decide whether a keyword is worth it or not:
1. Search volume
How many people search for that word. But careful: high volume is not always better. A word with 150 searches and high intent is worth more than another with 5,000 and informational intent.
2. Difficulty (Keyword Difficulty)
What it will cost you to sneak into the top spots. If those on top have authority, links, luxury content... go look for another one.
3. Search intent
Do they want to buy? Get informed? Compare? Look for opinions? Understanding this tells you how to approach the content.
4. Profitability
How much does that word bring you if you rank? Does it sell? Does it capture leads? Or does it just give you passing visits?
Keyword analysis tools that are worth it (no beating around the bush)
Straight to the point. These are the ones I use or have tried:
Free
- Google Keyword Planner
- Answer the Public
- Ubersuggest
Paid
- Ahrefs
- SEMRush
- KWFinder
- Serpstat
The important thing is not the tool (although if you need to combine terms quickly, try my keyword concatenator, in Spanish). It is knowing what to look at, how to cross data and how to apply what you see. Because having the hammer doesn't make you a carpenter.
How to interpret the data without going crazy (or blowing the budget)
The problem is not having no data. It is drowning in it. You open SEMrush and see CPC, KD%, volume, trend, links, competition... and your head explodes.
Here is the rule:
- If the word has intent and you can bring more value than the top 5 results: go for it.
- If not, leave it. Or save it for a longer article, cluster style.
To sum it up: don't be technical, be tactical.
The method I used to triple traffic with 3 well-chosen keywords
A year ago, I launched three articles. Three. Nothing more. All three started from keyword research that made sense. No "pretty words", but searches I detected with buying intent.
The result? Organic traffic x3 in 6 months. And the best part: traffic that converts.
What I learned doing keyword research for real businesses
I learned that:
- Most people don't know what they search for, but they do know what they want to solve.
- The best content ideas are not born in your head, but from seeing what people search for.
- Intent is more important than volume.
- Google doesn't reward whoever knows the most. It rewards whoever best answers what the user expected to find.
Conclusion: If you don't do this, your competition runs you over (and you don't even know it)
This is not optional. If you have a website and don't do keyword analysis, you are at a disadvantage. You are letting others take the space you could dominate. If you don't know where to start, write to me and we'll look at it together.
Do keyword research as if your business depended on it. Because it does.
Do it with judgment. With a good SEO strategy. And with guts.
Because this isn't about writing more, it is about writing better.
About having the focus where it hurts.
Where it converts.
