How to Do Keyword Research for a Blog
Pick blog topics people actually search for. Start from one idea, read volume and difficulty, check intent, and build a shortlist you can write from.
Most blogs fail at the first step. Someone picks a topic they find interesting, writes a good post, and then nobody searches for it. Keyword research stops that. It tells you what people type into Google, how many of them do it, and how hard the first page is to break into.
Here is a method that works for a new blog or a client's site.
Start from one idea
Pick a topic you can write about with authority. A bakery owner might start with "eggless cake". A freelancer who writes for software companies might start with "project management". One idea is enough.
Explore it with a country in mind
Search volume depends on where people are. A phrase that is popular in the United States may have almost no searches in India, and the reverse is also true. Choose the country and language of your readers before you read any numbers.
In Keyword Research, you type the seed, pick the market and run it. You get the keyword's own numbers, plus suggestions and related phrases in one table.
Read three numbers
- Volume. How many searches a month. It is an estimate, so use it to compare keywords with each other.
- Difficulty. A score from 0 to 100 for how hard it is to rank. A new blog should lean toward the lower end.
- Intent. What the person wants. Someone searching "how to bake eggless cake" wants a recipe. Someone searching "eggless cake near me" wants to buy.
Match your content to the intent. A product page will not rank for a recipe search, and a recipe will not convert someone who wants to order.
Look for easy wins
Filter for keywords with some real demand and low difficulty. In DataFlowSEO, the Easy wins filter shows keywords with a volume of 100 or more and a difficulty of 30 or less. Questions and long-tail phrases (four or more words) are often the best place for a new site to start, because fewer strong pages compete for them.
Group by topic
If you find fifteen keywords about the same subject, they probably belong on one page. Group them by topic, pick the main one for the title, and use the others as sections. This is how one good post ends up ranking for dozens of phrases.
Check the competition before you commit
Open the top results for your best keyword. Are they long guides from established sites, or thin pages? If the first page is full of strong sites, choose a narrower phrase. Our guide to writing a content brief shows how to read what those pages cover.
Build a shortlist you can finish
Ten keywords you will actually write about beat a spreadsheet of five hundred. Export the shortlist to CSV, add a working title to each, and give every one a month.
