Every blogger must want to use content idea generating tools to improve their content strategy, Here we listed 5 Tools For Generating Content Ideas for Your Blog

Google Correlate

The first tool is Google Correlate. Google correlate finds queries with a similar pattern to a target data series. So if I type in “build muscle,” then you can see that people are also interested in exercises, bodybuilding, they want to lose fat, build muscle, lose belly fat, and the list goes on.

So, the main reason with Google Correlate is you can find subtopics, which will help you maximize coverage on the topic and possibly get more organic keyword rankings. 

Plus, you can find hidden gems in here since the results are relational and not necessarily bound by phrase match or keyword matching as many premium tools do.


The two major cons of this tool are that there are no search metrics that accompany these keywords. And second, you’ll often find keywords that have a high correlation like this one but make absolutely no sense.

The next amazing tool is Keyword Shitter. This tool mines Google auto-suggest keywords based on a seed keyword. So if I type in “build muscle,” then it’ll start mining data.

The main pro of this tool is that you can generate thousands of related and long-tail keywords. They also have nice positive and negative filters to easily narrow down the list. 

For example, if I wanted to find modifier keywords, then I could enter in best, top, and the specific date like 2019 so it narrows our results nicely.

Anyways this tool has few issues. First, it can take quite a long time to find meaningful keywords. And It doesn’t have search metrics which can take a while to batch process in another tool. But this can be solved with the next keyword research tool and that’s Keywords Everywhere.

Keywords Everywhere is a Google Chrome browser extension that adds an inline view of search metrics on popular websites. You’ll need to install the extension, sign up for a free account, and then enter your API key into the settings. Now, when you go to any of these sites, you’ll get instant keyword metrics.

So if I go to Google search and type in a keyword phrase, then you’ll see the various metrics right beside your target search query as well as the autosuggestions. You’ll also see related keywords and other keywords that people search for on the right side of the search results page.


The best benefit of this tool is it contains search metrics for free considering Google Keyword Planner started restricting that data from users who aren’t advertising on AdWords. So that is awesome! But there is one very serious issue. 

As far as I know, they source their data through Google Keyword Planner alone. The thing is that Keyword Planner uses “buckets” to group keywords.

Search Engine Auto Suggest

The next tool is search engine auto-suggest. And no, I’m not talking about Google. There are numerous other search engines that you and I use every single day like Amazon, Pinterest, YouTube, and the list goes on.

So if you’re in a niche business like making homemade cards, then you might head over to Etsy and type in something like “cards.” And as the autosuggest populates, you can see all sorts of great keyword ideas like cards box with nearly 15,000 monthly searches, cards for boyfriend with 2,900 monthly searches and so on.

But remember, these search volumes besides the keyword are based on Google searches, and other. Suggestions from niche sites like this will likely produce better results than just using Google where the keyword “cards” can also be related to a game, bakeries or even finance like credit cards.

keyword tool

The next awesome tool is Google Trends. Using Google Trends, you can see the past and present the popularity of a keyword or topic. For example, if I search for “Nike Shoe,” you’ll see that the trend seems pretty stable over the past 12 months. So, if we change the Trends view to the past 5 years.

So, the main pro of Google Trends is you can do market research on a niche, product, or topic and get an understanding if it’s worth your time and effort to pursue. A con is that since Google Trends is based on popularity among all keywords and all topics, you won’t know anything about search volume or how much organic traffic this term can generate for you.


In my opinion, this tool is indispensable, so use trend data to get an understanding of whether your keywords and topics are worth targeting over the long haul. But you’ll need to pair it with a keyword research tool that provides accurate metrics to get a full scope.

keyword tool

And the final tool is another valuable tool and that’s Answer the Public. Just type your keyword then run the search and you’ll see that it has hundreds of questions, prepositions, comparisons, and more.

 If we go to the questions section and switch to the data view, you can see the search volumes since we have the Keywords Everywhere extension installed.


So, the top benefit is that you can long-tail keyword phrases here. This is a great way to get a keyword to your site to get traffic from potentially low competition keyword. This tool has an issue that is this stool is quite limited.
