Now, Guess which search query shows the Strong buying intention?

  • Laptop

“Laptop” is a seed keyword with the highest search volume.

The seed keyword does not show clear user intention. We can’t predict whether the user wants to know about a laptop or to buy a laptop.

Seed keywords are mostly used to get product information.

The visitors are at the Top of the Funnel of their Buyer’s journey.

Ranking for such a keyword is almost impossible. Because you are competing directly with the industry giants.

Ranking the seed keyword can help you acquire new visitors and later you can convert them into buying customers. For that, you have to put enormous effort into building high-quality lengthy content and link building for a very long time.

  • Best laptops under 20000 / Best laptops for students

These are the more specific and lengthy also called “long-tail keywords” with low search volume.

The long-tail keywords reveal the clear user intention behind the search query.

These are the keywords that can bring highly targeted traffic to your affiliate blog.

We can easily know whether the user’s intention is informational or transactional.

The visitors are at the Middle of the Funnel of their buyer’s journey. That means the visitors know about the product and looking for the best suitable one for them.

Chances are more that such keywords bring conversions.

Competition for such keywords is comparatively lower than the seed keywords and sometimes at the very low link-building effort; you can easily rank on Google.

  • Dell vostro coupon code

The visitors are at the bottom of the funnel of their buyer’s journey. That means the searcher made a decision for buying the product and now he is looking for any coupon code, discount, or offer to reduce the final cost.

The conversion rate for such keywords is very high.
