First things first. Think about the single word or phrase that you think people would type into Google before visiting your home page.

Maybe it’s a product that your site sells, a common problem that your customers face or a question that your website answers. Decide the keyword that best represents the benefit of going to your website and use it to start this process. Ultimately, a 1-2 word phrase will work best.

Keep in mind that keyword research should be flexible and creative, so you can always start the process over with a different keyword.

When you enter your keyword into the Semrush search bar, the interface presents a Keyword Overview report.

For the sake of example, let’s pretend we operate a website that offers gardening advice and products. I’ll go through the research process starting with “tomato plant.”

wOdePzNHU57sNaXeSr5YpOPc9ND74qlgk_c78e7ocF0-lLOr6wo91b-LCuOekH5HValhdtghWYwhKvKXtyMdQDNflO04-5r1NASQ4LM9b6BJ4ZPBCmnWj5actxu_vCAsEND4wD08

From this dashboard you can locate all of the data Semrush has about the keyword “tomato plant” are all shown at the top:

  • monthly search volume
  • number of results
  • cost-per click
  • search intent
  • competition level
  • Seasonal trends 

Keyword Variations, Questions, and Related keywords are previewed below, and will give you expanded lists of keyword ideas. If you click through one of these preview widgets you’ll open up the Keyword Magic Tool which is the next step.

2. Use the Keyword Magic Tool to Find Long Tail Keywords

SEO and PPC professionals classify keywords into three main buckets based on their popularity and specificity; the “head,” the “body,” and the “long tail” of the graph below that measures search volume and conversion rate of keywords. 

Head terms, also referred to as “short tail,” are often one or two word search phrases that do not have one clear intent. 

Body phrases are slightly more specific and usually contain more words. With more words in the search query, you can start to get a clearer idea of the searcher’s intent.

Long-tail keywords generally contain three or more words, have less search volume and illustrate a specific situation or intention from the searcher. 

The easiest way to think about these keywords is with the following graph.

img-semblog
long tail keywords can have high conversion rates

In this example: 

Head phrase: “tomato plant” is a high level query with high search volume.

Body phrases: “tomato plants for sale” / “when to plant tomatoes” show specific intent with lower average search volumes.

Long tail: “why are tomato plants turning yellow” is a very specific query with even lower search volume.

These are called “long-tail keywords” because they’re found in the long “tail” stretching to the right of the graph as search volume is usually quite low but the potential conversion rate is high as the query shows very specific intent.  

Generally speaking, as search volume decreases, more long-tail keywords appear and the conversion rate increases. 

Marketers can optimize their content to match long tail keywords for higher potential conversions versus head keywords that have high volume but much higher SEO and paid competition..

How do you find these high potential keywords? The best way to find long-tail keywords on Semrush is with the Keyword Magic Tool. This tool generates a list of extended search phrases based on the keyword entered. 

For example, let’s look at a Keyword Magic Tool report for the keyword “tomato plant.” If you have an Semrush account, click here to view this report.

From here we can see a long list of keywords based around the phrase “tomato plant,” ranked in order of search volume. 

That means that as you scroll down the report, you find the less popular and more specific keywords. 

You can also filter your report with the:

  1. questions filter 
  2. match type filter 
  3. subgroups on the left 
  4. filters for metrics like Keyword Difficulty (KD%), CPC, intent +more.

The long tail phrase, “why tomato plants turn yellow,” has less volume (1.6k) compared to the body phrases “when to plant tomatoes” (4.4k) and “tomato plants for sale” (4.4k) or even the head phrase, “tomato plant” (49.5k).

While the long tail phrase has the least volume, it will be an easier keyword to target because of how specific the query is.

To convert visitors, we'd inform them that one possible reason for yellow plants would be having low levels of nitrogen in the soil. Then, in addition to the information that answers their query, we could offer a solution, like a test kit to check the nitrogen levels of your soil.

See how that works? 

The more clear the user intent, the easier it will be for you to target a keyword, and the easier it will be to offer a relevant solution to the user’s problem. 

We'll explain how user intent fits into your marketing funnel in step 9 of this checklist.

3. Apply Filters for Keyword Difficulty (SEO) or Competitive Density (PPC)

Maybe you’re having trouble going through this long list of keywords to find the most realistic targets. Luckily, Semrush provides filters that let you weed out the highly competitive keywords that aren’t worth your time. 

In every keyword report, there are two helpful metrics that measure competition: 

  1. Keyword Difficulty for SEO
    • measured from 0-100
  2. Competitive Density for PPC
    • measured from 0-1.00

A higher Keyword Difficulty score means that there are authoritative domains ranking on the first page of results, and it will be hard to outrank the sites in the organic results. 

A higher Competitive Density score tells you that there are a high number of domains bidding on the keyword.

To attempt to rank a PPC ad for a keyword with high cost-per-click and high Competitive Density, you would need to place an expensive bid and set up a perfectly optimized landing page. Instead, you should focus on targeting keywords with low Competitive Density to start.

For SEO, you should focus on targeting keywords with low Keyword Difficulty. Oftentimes, there's a correlation between longer keywords and lower keyword difficulty and competition levels.

See how the competition and difficulty levels compare in our example:

RWBMU7tozZ6NDGorYMB_92jCI5N-ke1bQeiJ4MSnE7vKpfAJR4BZCNa4huvoZAsIVl0P-SehlrlPgxS6TLQy969VDB1oLVT-uSkU704t874LSpl5dIoRKyMpXi8ijiFp_TdYrqVv

As the phrases become more specific, the Keyword Difficulty and Competitive Density decrease. 

Interestingly, “tomato plants for sale” has a lower organic difficulty score than “when to plant tomatoes” despite having the highest competitive density. 

In this case, it would probably be easier to target “tomato plants for sale” through SEO efforts rather than advertising.

To analyze only the most targetable keywords, apply filters to weed out keywords with high Keyword Difficulty and Competitive Density scores.

Filters for both metrics can be applied at the same time to a report. See the example below where to find the filtering options.

4. Add Filters for Searcher Intent

This new intent filter by Semrush is a unique filter to analyze and focus on intent targeted keywords. 

The four types of search intent can tell you about a searcher’s purpose behind making a search. 

Informational intent indicates an interest in gathering information, while transactional and commercial intent indicate an interest in taking action or making a purchase in the future. 

Navigational intent indicates a searcher is simply using the search engine to get to a specific page or website on the Internet. 

Therefore, depending on the goals of your campaign, you should look for different types of intent. 

Do you want to grow your brand awareness and build authority? Add a filter for informational intent and find keywords that you can target with helpful educational content.

Do you need more high intent traffic that will bring conversions? Filter for transactional intent to inspect these keywords.

Again, these filters can be combined with the filters mentioned above. For example, a filter for commercial keywords + easy keyword difficulty could uncover opportunities for attracting valuable traffic.

5. Send the Filtered List to Keyword Manager

This step is pretty straight forward, but necessary. Every time you generate a filtered list of terms, make sure you send it to the Keyword Manager

This lets you combine all of your research into a master file of up to 1,000 keywords. When exporting keywords from the Keyword Magic Tool, you can choose to select all of the keywords, the first 100, the first 500, or on an individual basis using the checkboxes in the far left column.

Zg5zqXI5js3qw8HwoDc0I3sCoha2S7qOOGmylALVR0zYdf_ITvB73bZSvtmCCyk22Naojls-TmpDu-Odh5UtElIEZS_l0Z79paLoGvzKpkVJusUUEiiHNanJXeJpGYStMsMedX4u

After finding Phrase Matches based on your original keyword, you’re going to want to identify more closely related searches. While keeping your main keyword in the search bar, change the Phrase Match filter to a Related filter.

The keywords in this list are based on their relevance to the queried keyword or how similar the search results of these keywords are to the search results of the queried keyword. 

This allows you to find more search phrases related to your topic that may not even contain your main target keyword in the query.

SSdCD1LSNZYaT_u8wnucu-vfDKaWsl2sjLdcvqvUqsiK7rpxvFOmOExqgzS3_SYqv_ZL_D-TrekGl5tCDuBCPL9wzFKGMJHo2OCIVSCbl774UaL0Mj9l9pUscCp3T5QoQSRtYqGB

Again, this report can be filtered by Keyword Difficulty and Competitive Density. Pick out every related keyword in this list that sticks out to you and send the list to your Keyword Manager list.

7. Repeat Steps 2-6 for Any Additional Keywords

Repeat the process that you went through with your original keyword but with additional topics that you think your site should target.

Enter your first new topic into the search bar and pull another Phrase Match report with any desired filters.

Once you gather another list of target keywords, export the list and repeat for every related topic you want to target. Send all of your exports to the same list within Keyword Manager.

8. Refresh Metrics of Your Master List from Keyword Manager

The next step is to export your master list from Keyword Manager. The great thing about this tool is that you can actually refresh your metrics before exporting to be sure that your exported file has the freshest metrics. 

Just hit the “Update metrics” button above your list to get the most recent Semrush data on competition level, KD%, SERP Features, Click Potential and top competitors.

Once your list is updated, the rows will be green and you’ll see up-to-date click potential and other metrics.

Next, export your list to a spreadsheet file. 

This spreadsheet will be a valuable reference document as you go through your SEO or PPC campaign. 

There will be columns for keyword, search volume, keyword difficulty index, CPC, competition level, number of results, and trend. Number of results and trend won’t matter too much in this process, so you can either ignore those columns or delete them from your spreadsheet.

A simple trick to help organize your spreadsheet is adding Conditional Formatting to colorize the metric columns. 

First, add filters to your document and highlight the column you want to format. 

Then, make sure you’re under the “Home” tab and select Conditional Formatting to add a color scale to each column that measures value (volume, KW difficulty, CPC, and Competitive density).

img-semblog
Use conditional formatting to add color to your spreadsheet

Volume — green for high, red for low

KW Difficulty — green for low, red for high

CPC — green for low, red for high

Competitive Density — green for low, red for high

Adding color to these metrics will go a long way in helping you visualize and pick out the most realistic and rewarding keywords to target. Now you can scan for the most “green” keywords, signifying the most volume and least competition. The next step will be more tedious if you have a huge amount of keywords, but will prove to be rewarding over time.

9. Cluster your master list by keyword intent and map your keyword strategy to intent

This last step uses a bit of critical thinking, but will be essential for maximizing the use of your research. 

In addition to knowing what your audience searches (keywords), you'll want to focus on why they make these searches (intent).

There are tons of articles written by SEO experts about how to classify intent and separate keywords with low and high intent.

Searcher intent is essentially the goal of the person searching on Google. They could be looking for general information, product research, or a website to make a purchase.

Semrush groups keywords into four categories of intent:

  • Informational — Searches looking for general information or answers to specific FAQs. Keywords with who, what, where, why, and how indicate this intent a lot. Single-word keywords like “tomatoes” or “gardening” fit in this bucket.
  • Navigational — Searches looking to find a specific physical location or location on the internet. “Tomato pie cafe harrissburg” would fit in this bucket because the searcher wants to navigate to a specific store.
  • Commercial — Searches looking to investigate products, services or brands. “Best,” “mens,” “womens” or other product modifiers commonly indicate commercial intent. “Best fertilizer for tomatoes” is an example.
  • Transactional — Searches with a high intent to buy or take action (like downloading files or signing up for a newsletter) in the most immediate future. Keywords asking about price, coupons, shipping costs, and the transaction process make up this bucket. “Buy cheap tomatoes,” for example.

The more specific the intent is for a keyword, the easier it is to provide searchers with what they are looking for. 

To go one step further, searcher intent can actually be aligned with your marketing funnel. 

The easiest way to do this is by mapping the four intent buckets to the AIDA (Awareness, Interest, Desire, Action) model. Like searcher intent buckets, AIDA has four stages.

img-semblog
AIDA marketing conversion funnel

Awareness (general knowledge of information) is the first step of the funnel, leading into Interest (curiosity in the subject), then Desire (wanting something to solve a problem), and finally, Action (buying a product, signing up for a subscription, etc).

Once you identify a keyword’s searcher intent, you can classify where in the conversion funnel it lies. Every keyword in your strategy also has a place in your marketing funnel.

img-semblog
AIDA + User Intent = Strategy

Go back into your keyword list and now sort the list by intent. What you can do from here is plan out your website/marketing strategy based to align your messaging with the intent of each search.

The four different stages of conversion should be targeted with different areas of your site, and by identifying the keywords that fit each step of the conversion funnel, you can conduct an optimized marketing campaign.

For example, you can target all of the informational queries with educational, top-level content that answers people’s questions. 

For navigational keywords, you should check to make sure your site is easily found for each search. If it's not, see how you can optimize your branding/overall visibility, especially if there are technical issues with your site.

Lastly, commercial and transactional searches could be targeted more aggressively with paid ads and landing pages that make it easy for searchers with the intent to buy to make their purchase/buying decision.

Ending Thoughts

Hopefully, this checklist can help you build your first master keyword list and learn more about your specific search market. Research the best keywords in your market and create a master list to plan your SEO and PPC around. 

A thorough target keyword list is an invaluable resource to any SEO, PPC or content strategy. If you can master this process, you’ll be developing a great skill that can help you in all areas of digital marketing.
