4. YouTube Autocomplete

YouTube Autocomplete

YouTube is the world's second-biggest search engine, and billions of searches are being performed on YouTube every single day.

And you can use this data to perform in-depth keyword research for your YouTube videos.

But how can you access this data?

It's simple - by using the autocomplete feature of YouTube search.

The autocomplete feature of YouTube search can be an excellent tool for you if you want to get inside the huge keyword database of YouTube and want to know what people are actually searching on that platform.

And most importantly, it's super easy to use.

Just head over to YouTube, enter your seed keyword on the search bar, and hit space on your keyboard.

And YouTube will immediately start showing you long-tail keyword ideas around the seed keyword you've entered.

You can repeat this process multiple times to find out new keyword ideas that people are actually searching on YouTube.

This is basically a manual process, and it's definitely going to take some time.

But at the end of the day, the keywords you'll find out using this method will mostly be untapped or really low competitive.

However, one of the biggest disadvantages of this method is that you won't be able to see the keyword search volume and trend data.

Sure, you can use Google trends to know the trend graph of the keywords, but still, you'll be unaware of the potential search volume of those keywords.

And you'll be left with just one option that is "guesswork".

Although if you can combine YouTube autocomplete with any YouTube keyword research tool like Zutrix that can show the search volume of the keywords, then it can work like a charm.

Highlighted features of YouTube autocomplete:

  • Super easy to use

  • Authentic and 100% correct data

  • Find out plenty of untapped keyword ideas that even some tools can't find.


Completely free until YouTube is alive.

Most importantly, you'll be able to see the search volume, trend, CPC, and competition of the keywords right inside the dashboard.

But keep in mind that the keyword metrics are available only for the paid users, and free users can only see the keywords, not the metrics.

6. Google Trends

Google trends

As you know, YouTube is all about trends except few evergreen topics.

When you're starting out your YouTube channel and want to grow it as quickly as possible, you have to target trending topics around your niche rather than targeting the evergreen topics.

Because targeting trending keywords or topics will not only give you a massive initial boost, but those keywords are comparatively easy to rank for as well.

Even if you have a list of keyword ideas for your YouTube channel, you have to make sure that the trending graph of those keywords is going upward and not downward.

For example, a few years back, fidget spinner was a very hot and trending topic.

But now, it's almost vanished. No one cares about it anymore.

In short:

Trend comes and goes at a very rapid pace.

So if you want your videos to go viral and shoot up to the moon, you have to target trending keywords or at least the keywords that are not going downwards on the trend graph.

But how will you find out the trend report of the keywords?

Well, there's an outstanding available tool for that.

And that is - Google trends.
