5 Keyword Research Tips
Having the right tool is just the beginning. The techniques can help you find more opportunities to make your guest posting effective. Here are proven keyword research techniques I use:
1: Target Long Tail Keywords First
Example:
- You should use a keyword like “digital marketing for beginners’ step by step” instead of “digital marketing“.
Reason: These long-tail keywords usually show less competition, and they have a strong potential to attract people who are ready to take action.
2: Find Question Keywords
Your focus should be those People who are searching with questions because they are always looking for detailed answers. Use tools like AnswerThePublic to find:
- “What is SEO?“
- “How can SEO help the business grow fast?
- “Why to increase sale with the help of SEO?
3: Analyze SERP (Search Results)
SERP results consist your competitors. You should make it your habit to search your topic or keyword on google or any other search engine. Top 10 results are the best links to help you understand the worth and popularity of your keyword. Evaluate those top 10 results with your own answers to the following questions:
- Do they have strong authority? (If yes, then it is hard for you to compete them.)
- are they small blogs with low ranking? (If yes, then they can be a good opportunity.)
- What type of content they have? (Do they have articles, blogs, videos, or lists?)
4: Use Keyword Difficulty Filters
Use of Keyword difficulty filters in some SEO tools like KWFinder or SEMrush can help you more:
- Define keyword difficulty to “Easy” or “Medium”
- Focus on difficulty scores below 40
- Gives real and fast ranking opportunities
5: Check Search Intent
The last technique is to make sure your content matches what people actually want. People show their intention differently. Usually, they are looking for:
- Informational Content: “what is,” “how to,” “guide”
- Commercial Content: “best,” “top,” “review”
- Transactional Content: “buy,” “discount,” “near me”
Common Mistakes of Keyword Research (How to Avoid Mistakes)
1: Targeting high-competition keywords is a big mistake
It is essential for you to focus specific keywords that are low-competition keywords with difficulty scores under 30.
2: We often Ignore search volume of our target keyword.
Targeting the keywords with search volume (at least 100-500 monthly searches) can be beneficial for your SEO because the search volume shows users’ intent.
3: Using Only One Tool create confusion and mess for you to understand the keyword.
You may use different tools to get the best results because each tool has different data. I recommend you to use at least a combination of two keyword research tools.
4: Forgetting About User Intent can be your big mistake in the journey of developing keywords research strategy.
Before creating online content you may read the top-ranking articles. It will help you target and understand what people actually want to know.
5: Keyword Stuffing is one of those mistake that we often ignore. It is actually use of one keyword 50 or 60 times in a 1000-word article. Keyword stuffing hurts your SEO.
Main keyword should only be used 3-5 times naturally. You can also use other long-tail keywords throughout your article contextually and naturally. This type of keywords strategy helps you rank higher.
