What is Keyword Research?

If you are new to affiliate marketing, we have posted a beginner’s guide to keyword research for affiliates that can be found here.

Still, to effectively research keywords, you’re going to need to invest in some keyword research tools. Keyword tools not only allow you to compile lists of keywords relevant to your niche, but most also have competition analysis tools.

What is Keyword Research?

By analyzing the competition within your niche, you can see what keywords your competitors are targeting – and also how they are ranking for them.

This strategy not only informs you of the keywords you should be targeting but allows you to discover keywords your competition might not be targeting – meaning there is room for you to operate in that space.

If you are a newcomer to the world of affiliate marketing, you may be scratching your head wondering what a keyword is.

In digital marketing talk, a keyword is any search query used in a search engine that has a significant volume of searches.

For instance, if I was interested in photography, I may search Google for ‘camera lenses.’ – I can see from my keyword research tool that the phrase ‘camera lenses’ has a monthly search volume of 5100.

I can also see that the top 10 ranking websites for that keyword are highly authoritative, meaning it would be tough for me to rank for that keyword. If you are wondering what I mean by authoritative, most keyword research tools use a metric to determine how powerful a website looks in Google’s eyes.

The more authority a website has, the higher the likelihood is that Google will rank it – authority is basically a trust score.
The more trusted a website, the better it performs.

However, if I search the term ‘camera lenses for beginners,’ I can see that there is 100 monthly search volume, and some of the sites that currently rank in the top ten have much less authority. Competing for this keyword should be much less difficult and will allow me to build the authority of my own site and, in turn, compete for higher difficulty keywords.

For this reason, it is always advisable for new affiliate marketers to target lower volume, low competition keywords. You won’t generate as much site traffic, but the traffic you do get will be highly targeted and easier to convert into sales.

If any of this seems confusing, don’t worry. Some of what was just mentioned won’t seem apparent until you are using keyword research tools regularly.

Moz Pro is a fully realized all-encompassing SEO toolset, including Moz’s keyword explorer. Regrettably, Moz keyword explorer isn’t currently available as a stand-alone product; however, if you’re looking for an all-in-one SEO solution, this may be it.

This is a simple yet effective way to develop months’ worth of content ideas from a single keyword.

Often underappreciated by marketers, but Reddit can deliver a lot of valuable information for affiliates, providing insight on trends your current audience might be interested in.
