Semrush Keyword Research Tool

Semrush is one of the best SEO tools online, used by over 10m marketers across the world.

Alongside being an all-in-one SEO tool, Semrush has a couple of excellent tools for keyword research, including the Semrush organic research tool, keyword overview report, and the keyword magic tool.

The organic research tool allows you to run competitive analysis on any domain, to see where your competitors are getting their organic traffic from.

This includes the organic keywords they are ranking for, estimated organic traffic, and the total cost of that organic search traffic if you were to pay for the same traffic via PPC.

Here's a snapshot of Semrush's organic research report for Techradar, a popular technology blog.

Using the organic research tool, you can then drill down further to look at top organic keywords, as well as top organic position changes and their impact on organic traffic.

By clicking on the top organic keywords, you then get a full breakdown of the keywords that are driving traffic, which you can filter using an advanced filter to isolate the pages and keywords that might be interesting for your business.

This is a great way to examine competitors in your niche to see where they are ranking, and how you can leverage their strategy to drive your own organic search traffic.

Once you have found a keyword you would like to research, you can then drill down into that seed keyword to learn more using the Keyword Overview tool.

              It's possible to analyze key metrics like total clicks from organic search, total search impressions, click-through rate, and average position down to the keyword level.

              You can also cut the data by page, country, device, or whether your site is appearing for a specific SERP feature.

              Here is a breakdown of clicks and impressions from our Google Search Console instance for the past 7 days.

               Visualize Value Google Search Console Impressions

              You can then drill down into specific queries and pages in order to assess which keywords and pages are working most effectively.

              Visualize Value Top Keywords

              One of the best ways to use Google Search Console for keyword research is to analyze which terms you are already ranking on, and where you can create new pages to better target sub-niches to increase overall rankings.

              For example, we built a page that ranked the best SEO tools online. This page started ranking on a huge number of keywords, driving thousands of impressions from organic search.

              However, when diving deeper using Google Search Console we noticed that the page was also ranking on a number of terms of relating to 'keyword rank tracking'.

              Off the back of this analysis, we created a dedicated page, which now does a better job of ranking against those target keywords.

              Visualize Value Rank Tracking Keywords

              Google Search Console is a free keyword research tool and it's very easy to set up once you have an active site driving traffic from Google.

              We'd recommend always analyzing the keywords your pages are already ranking for, to see whether you could create more narrow content to improve your rankings.

              Features we like

              • Search results - discover how your website is performing in organic search, assess clicks, search impressions, click-through rate, and average position over time

                Jaaxy keyword research tool

                Jaaxy is a keyword research tool for affiliate marketers which is really easy to use.

                Jaaxy provides you with 30 keyword searches per month for free, and it's possible to buy access to Jaaxy's paid tools to extend this.

                    Google Keyword Planner

                    Alongside Google Search Console, Google offers another excellent free keyword research tool called Google Keyword Planner to help business owners generate keyword ideas.

                    Simply sign into your Google account and head over to the Google Keyword Planner where you will be presented with the option to discover new keywords or get search volumes and forecasts.

                     Google Keyword Planner

                    By selecting the 'discover new keywords' option, you can then opt to either enter a website or a seed keyword to understand what keywords drive the most monthly search volume in your area of interest.

                    Discover New Keywords

                    Like some of the best paid keyword research tools out there, Google Keyword Planner shows a range of keyword ideas, including average monthly search volume, competition level, and monthly/yearly change metrics to show you whether the keyword is trending or not.

                    Google Keyword Planner Results

                    We have noticed when comparing Google's keyword research tool to other paid options, that Google's free tools do not offer the same granularity in terms of keyword suggestions, and that their search volumes are fairly generic.

                    This makes it more difficult to plan using this data set, but it's an added bonus that Google offers the data for free.

                    One thing that we do like is the 'broaden your search' option which gives you the ability to pull in new keyword ideas based on Google's recommendations.

                    Broaden Your Search Feature

                    Here you can see that we have included the term 'digital marketing strategy in our analysis, based on Google's recommendations.

                    Straight away we can see a smaller monthly search volume for this term, but it's still worth potentially going after as part of our strategy.

                    Features we like

                    • Free to use - while there is not the same granularity in Google Keyword Planner vs other paid tools like Semrush or SE ranking, it's great that it's a free tool that can guide our analysis
                    • Broaden your search - Google's keyword suggestions are very helpful in showing you where the volume within your niche exists

                          It's no surprise to see big news events like 'Queen Elizabeth Passing', or 'Ukraine' sitting at the top of the list when it comes to top trending search terms.

                                  Keyword research tools are a valuable part of any SEO toolkit and an essential service for anyone looking to drive traffic from search engines.

                                  Ultimately, if you don't know what people are searching for, and how popular those search terms are, then you cannot design an effective strategy to drive traffic from organic search.

                                  Here are some of the top reasons to invest.

                                  • Search volume - keyword research tools help you accurately assess the estimated search volume for a keyword or keyword group. If you are looking to launch new content, re-design your site architecture, or launch new products and services, it's important to understand what demand exists in the market

                                  • Competitor analysis - using the best keyword research tools you can easily understand which pages are most important for your competitors in driving traffic from search engines. Keyword research tools allow you to assess performance down to keyword level

                                  • Keyword ideas - if you're unsure what content to produce, keyword research tools can help you find the right keywords for your strategy. If you are looking to include long-tail keywords in your search copy, keyword research tools can show you all of the phrase match keywords, related keywords, and question queries relating to your keyword

                                  • Position tracking - some of the best keyword research tools also allow you to set up keyword position tracking. SEO tools will scan your target keywords and give you up-to-date information on how you are currently ranking, and how your rankings are changing over time

                                  • SERP features - targeting SERP features like featured snippets is a great way to increase your visibility in search engines. The best keyword research tools help you identify which SERP features are active on the keywords that you're targeting

                                    • Are you looking for an all-in-one SEO tool or a dedicated keyword research tool?
                                    • Do you want to use free keyword research tools or do you have budget to invest?
                                    • Is it important to complete competitor analysis as part of your keyword research?
                                    • Do you need to be able to set up position tracking?
                                    • Is it important to also complete paid keyword research?

                                      The best keyword research tools like Semrush and AHREFs take care of the majority of keyword research tasks. But they do come at a cost of around $100 per month.

                                      If you are operating on a restricted budget then you should check out SE Ranking or Keyword Finder by Mangools. Both tools offer the same functionality, without breaking the bank.
