In this post we are going to go into what Semrush is and how bloggers use it for keyword research.
If you’ve spent any time looking into blogging or SEO/keyword research, you will have no doubt come across Semrush at some point.
It’s one of those tools that gets mentioned everywhere. In blog posts, YouTube videos, and by the people who seem to know exactly what they’re doing when it comes to growing traffic lol.
But if you’ve never used it yourself, it can feel a bit confusing like any new tool. As in, what does it actually do? And more importantly, how are bloggers actually using it when it comes to keyword research?
In this post, I’m going to break it down in a really simple way even if you’re a beginner, so you can understand what Semrush is, what it’s used for, and how it fits into blogging… without all the technical jargon.
What Is Semrush?
Semrush is a well-known and trusted SEO and keyword research tool that shows you what people are actually searching for on Google. This includes metrics such as how popular those searches are, and how competitive they are to rank for.
But, more importantly, it’s the difference between creating content that might work… and content that actually has a chance to get seen.
Before using a tool like this, it’s very easy to just write whatever feels like a good idea and hope people find it. Sometimes that works… most of the time though, it doesn’t.
Semrush changes that.
Instead of guessing, you can literally see exactly what people are searching for. This includes how many people are searching for that term, and how difficult it would be for your content to rank. So you’re not just putting content out and hoping for the best, you’re putting out content by making decisions based on what’s already working.
I’ve got a full post on keyword research if you want to understand that side of things properly first. You can read that here.
The reason for needing Semrush at its core, is really simple:
It helps you stop guessing and start creating content that actually gets seen.

What Does Semrush Actually Do?
Semrush has a lot of features, but for blogging and keyword research, you don’t need to overcomplicate it. Most bloggers are using it for a few key things.
First, it helps you find keywords; the actual phrases people type into Google. This could be anything from “how to start a blog” to “best email marketing tools for beginners”.
It also shows you how many people are searching for that keyword and how competitive it is, which helps you decide whether it’s worth targeting or not.
Another big feature is competitor insights. You can see what other blogs are ranking for, which can give you ideas for your own content or highlight opportunities you might not have thought of.
And finally, it can help with content ideas in general. Instead of staring at a blank page wondering what to write next, you can use it to find topics people are already interested in.
Why Do Bloggers Use Semrush?
One of the biggest challenges with blogging is knowing what to write about.
It’s very easy to come up with ideas that sound good, but if no one is actually searching for them, they’re unlikely to bring in traffic.
The same can be said if people are searching for your chosen search terms, but there are so many others writing the same sort of thing that ranking becomes really difficult.
This is where tools like Semrush come in.
It’s literally what it was designed to solve.
Instead of guessing, you can base your content around real search data. That means you’re creating posts that people are already looking for, which gives your content a much better chance of being found.
It can also help you avoid overly competitive topics and focus on keywords that are more realistic to rank for, especially when your blog is still growing.
For bloggers, it takes away a lot of the guesswork and makes their content planning feel much more intentional and pointful.
How Bloggers Use Semrush for Keyword Research
Most bloggers don’t use Semrush in a complicated way. They use it to take an idea and turn it into something people are actually searching for.
Usually it starts with a broad topic idea that then gets narrowed down.
You might know you want to write about a topic such as Pinterest, affiliate marketing, or starting a blog, but you’re not sure what angle to actually take, or what people are actually typing into Google.
Instead of guessing, Semrush shows you real search data (all the bits you need to know before creating the content).
You can find related keywords on whichever topic you choose.
You can then see exactly how people are searching for that topic. This is the biggest thing that will change if/how your content gets found. You can also find more specific phrases that are often easier to rank for. This could be things that you may never have even thought of.
What this then means is that you can stick to the topic you want to write about, just in a way that people are actually searching for and are therefore a lot more likely to find.
Once you have done that you can then also look at key metrics for those terms. This is things like search volume (how many people are searching for that term) and keyword difficulty (how competitive it is) to decide whether it’s worth focusing on and writing content for.
Once you’ve chosen a keyword, you then build your content/post around it and naturally include related terms throughout your content.
It’s not about making things overly complicated or getting everything perfect. It’s about replacing your own guesswork with a solid/reliable direction, so you can create content people are already looking for. The whole point is for your content to get found afterall!
What This Might Look Like in Practice
Let’s say (as an example) that you want to write a post about making money online.
Without keyword research, you might just go with a broad title like “how to make money online”.
In theory this sounds good but ideally it could be better (from a searchable point of view).
With a tool like Semrush, you will find more specific searches. Things like:
- “how to make money online for beginners”
- “ways to make money online from home”
- “how to make money online with no experience”
While they feel and seem very similar, these are the types of phrases people are actually typing into Google. This in turn then makes them much more useful for building your content around.
People will only find the content they are actively searching for.
Semrush vs Simpler Keyword Tools
There are a lot of keyword research tools out there, and some of the simpler ones can be a good starting point if you’re just getting used to SEO.
Tools like Keysearch are often seen as more beginner-friendly and more affordable, but they also tend to offer more limited data.
It really is one of those things that you get what you pay for, so it depends how far into your blogging journey you are as to which tool is best for you.
Semrush, on the other hand, gives you a much (much) deeper level of insight. You’re not just seeing basic keyword ideas etc, you’re getting really detailed data that helps you make more informed decisions about what to write, what to prioritise, and where your best opportunities are.
That’s why many bloggers either move to Semrush as they grow, or choose to start with it from the beginning so they have access to everything in one place.
Who Is Semrush Best For?
Semrush is ideal for bloggers who want to grow their traffic faster and stop guessing what to post next.
It’s not really aimed at brand new bloggers so if you are really new into your blogging journey you can absolutely go for a more basic keyword research tool such as KeySearch.
If you’re past the stage of being a new blogger and you are already posting consistently and want to start seeing real results from your blog, this is where a tool like Semrush can make a huge difference for you.
While you can blog without it, using Semrush gives you a clear advantage. It helps you to make smarter content decisions, save time, and build traffic much more efficiently as your blog grows.
We all know the phrase “Work smarter not harder” and this is basically what Semrush helps with.
Is Semrush Worth It for Bloggers?
Honestly? Yes.
That is if you’re at the point where you want to grow your blog properly and not just guess your way through it.
Like any tool, it’s most useful when you’re actively creating content and applying what you learn from it to enhance and refine that content.
Semrush is one of those tools that’s recommended everywhere for a reason.
It gives you real insight into what people are searching for, what’s already working, and where your content actually has a chance to rank and be seen/found.
If you’re actually serious about increasing your traffic, finding better keywords, and creating content that performs, it can make a huge difference.
That said, whether it feels “worth it” for you will come down to how you use it. It’s the kind of tool that pays off when you’re actively creating content and actually applying what you’re learning, not just letting it sit there unused of course.
If you’re ready to take your keyword research a bit more seriously, this is where you can try Semrush:
How It Fits Into Your Overall Blogging Strategy
Keyword research is just one part of blogging, but it’s one of the things that makes everything else so much easier and more worthwhile.
As I mentioned earlier in this post, the way it usually works is pretty simple. You start with what people are already searching for, create content around that, and over time that content brings in traffic. Then that traffic can turn into email signups, affiliate clicks, and then in turn, income.
Without that step, you’re basically just guessing and hoping your posts get found. Some might, others won’t. And writing content that never gets seen is not how we go about running a successful blog.
That’s where Semrush comes in. It doesn’t change what you’re doing, it just makes the whole process a lot clearer for you from the get go. You can actually see what people are searching for, what’s worth focusing on, and where your content has a real chance of ranking, which makes it so much easier to create posts that actually get found.
