What is Keyword Difficulty and Why Does Picking the Right Keyword Matter?

Keyword Difficulty

Keyword difficulty, meaning, is a measure that forecasts the difficulty level that should be involved in achieving a high ranking on Google for a particular keyword. The correct term for keyword difficulty is keyword ranking difficulty.

Today we'll be exploring what the keyword difficulty scores mean in keyword research tools.

What is Keyword Difficulty?

The keyword research process of assessing the difficulty of ranking for a given term in Google's organic search results is known as keyword difficulty, also referred to as "SEO difficulty" or "keyword competition.". Domain authority, page authority, and content quality are just a few variables that affect how difficult a keyword is to rank for.

Whatever you call it, the advantages are obvious: determining the difficulty level enables you to calculate how much work is necessary to achieve a high ranking on a SERP (search engine results page). Thanks to this, you can more accurately plan time and resources while also modifying your keyword strategy.

When determining and displaying keyword difficulty, or KD, different SEO and keyword tools employ different methodologies. Some show a numerical value, while others offer a percentage. In essence, the primary consideration in all free keyword research tools is the number and calibre of backlinks to the websites that are at the top of the search results for the keyword.

Why Is Keyword Difficulty Important?

To understand keyword difficulty, you should note that it's a crucial step in the keyword research procedure. You can choose the best keywords for SEO by taking into account keyword difficulty, monthly search volume, and other elements.

The only problem is that each tool calculates keyword difficulty differently.

Popular keyword tools' difficulty rankings varied widely, according to a recent analysis we conducted, even for the same keyword.

Therefore, you need to look beyond the numbers the tools spit out to get a REAL sense of how difficult it will be to rank for a keyword.

How Is Keyword Difficulty Measured?

Many metrics from different tools can be used in measuring keyword competition.

The terms "keyword difficulty" and "keyword competition" or "keyword competitiveness" can be used interchangeably in some situations. You might also hear some SEO experts in the field refer to it as simply "competition" or "competitiveness".

Moz

Moz's keyword research tool, Keyword Explorer, was the first to use "keyword difficulty" (KD).

Moz assigns a value between 1 and 100, where 100 is challenging to rank for, and one is easy.

However, the company does state that it considers page authority (PA), domain authority (DA), and anticipated clickthrough rates (CTR). Moz does not disclose its precise, proprietary formula for how it is calculated.

Google does not use Moz's proprietary metrics PA and DA.

These metrics are an effort by Moz to create a quality metric that would stand in for Google's PageRank score, which was once a score that was made available to the general public.

To determine these scores, Moz uses well-known ranking factors that Google also considers.

The keyword difficulty metric in other tools may frequently come from Moz because it has an API.

Ahrefs

According to Google, the top ranking metrics for your site's placement in search results are links and the relevance of the content. The findings of two million keywords support this claim. A website's number of referring domains and ranking in Google search results are strongly correlated. Competition only applies to paid search results, whereas "Keyword Difficulty" does so for organic search results.

The number of referring domains the top 10 ranking pages have is what Ahrefs considers when determining the keyword difficulty. The higher the Keyword Difficulty, the more referring domains across the top-ranking pages.

Semrush

You can determine a keyword's relative difficulty using the Keyword Difficulty Score metric (KD percent) in Semrush. It is shown as a percentage, ranging from 0 to 100. A keyword would be easy to rank for with a score of zero, whereas the most difficult one is one with a 100.

The authority of the pages currently ranking, the quantity and quality of their backlinks (including their follow/nofollow ratio), and other keyword-specific information are all factors Semrush considers when determining the difficulty of a keyword.

Google Ads Keyword Planner Competition Metric

The Google Ads Keyword Planner Competition metric is preferred by some SEO specialists.

According to Google, this value represents how many advertisements were displayed for each keyword concerning all other keywords.

This is frequently expressed as a number between 0 and 1, with 1 being the hardest to rank for and 0 being the easiest, with two decimal places.

It's crucial to remember that this tool was created with Google Ads users in mind.

The rationale behind this metric, however, is that keywords that are more difficult to rank for in pay-per-click (PPC) ads are frequently also those that are more difficult to rank for in organic search.

Google Ads Keyword Planner CPC Metric

The CPC Metric of Keyword Planner is primarily designed to be used by Google Ads advertisers, much like the competition metric that was previously mentioned.

Cost per click, or CPC, indicates a keyword's competitiveness in the organic market.

The CPC metric you see will be the typical CPC.

Because more people are willing to pay more to rank for a keyword in PPC, the harder it is to rank for a keyword, the more SEO professionals may choose this strategy.

Since this is a cost, the values are expressed in dollar amounts ranging from a few cents to several dollars but typically stay below $10.

Difference between Keyword Competition and Keyword Difficulty

For organic search, Google rates the difficulty of each keyword on a scale of 1 to 100. Additionally, Google offers a keyword competition metric, and the two are frequently combined in the same sentence. For paid search campaigns, you'll consider keyword competition, which assesses the bidding competition for a particular keyword.

For your keyword research, keep in mind the following:

When we talk about keywords, we talk about paid search when we talk about keyword competition.

How do you estimate keyword difficulty?

A keyword difficulty measure can be found in a variety of tools. Even though scoring is always based on Google's ranking factors, each is distinct. Backlinks and content relevance are the two primary ranking factors for Google.

When calculating keyword difficulty scores, the quantity of high-calibre links pointing to pages that rank highly is considered.

The algorithm, for instance, would look at the top-ranking pages for the keyword "hot air balloons" and count the number of backlinks on these pages. There are, of course, additional considerations.

Backlink quality

Google wants to deliver high-quality content to users and strives to be ranked accordingly. Realness, integrity, and dependability of the websites and pages that link to the site are factors to be considered.

Respectable websites won't link to dubious or sketchy websites. For instance, links to research centres and libraries can be found on university websites. These are factual, reliable sources of information. Links to these kinds of websites produce a compelling link profile.

Link profiles are one of Google's methods for assessing a website's or webpage's quality by looking at the kind of content it is linked to.

It makes sense that getting a high-link profile is challenging. That's where keyword difficulty comes into play. It is more difficult to rank for a keyword if the high-ranking pages for it have a solid link profile.

You must establish credibility and demonstrate your subject-matter expertise to be linked to such pages. This brings us to the following element: domain authority and page authority.

Domain authority

Although it considers relevance, domain authority has to do with content quality. A website is regarded as an authority if it consistently publishes advantageous and current expert content on baking. It takes time and works to establish authority. Your site's domain authority will remain low once it can produce enough high-quality content for a particular sector or subject.

Referring Domains

Google is a vote-collecting engine.

A page typically ranks higher as it receives more "votes" (in the form of backlinks).

The number of referring domains was the factor that was most strongly correlated with higher rankings (I don't think links are important anymore).

As a result, one metric that is unquestionably worthwhile to examine is the number of referring domains.

Numerous link analysis tools are available, so there is no shortage of contradictory information regarding the number of links that point to a particular page.

Content quality

A strong link profile can only be achieved with high-quality content, a prerequisite for domain authority. Glad you asked, but if so, why take content quality into account separately?

Imagine that the keyword refers to a brand-new class of product idea. As of now, there are only a few authoritative websites. Naturally, there are also no high-quality backlinks. The content itself is the only SEO metric of quality, and the pages with the best content perform best.

Let's now examine this from the standpoint of keyword difficulty. Ranking highly for the keyword is simpler if none of the websites offers high-quality content. Delivering top-notch, relevant content is all that's required. This explains why keyword difficulty calculations take content quality into account.

Therefore, the only way for a new website without any backlinks or authority to rank well is through accurate, wise, and keyword-relevant content. The content's quality is crucial in this situation.

Search intent

Content must be highly relevant to the targeted keyword and align with the search intent (note that we said "keyword-relevant").

Google categorizes search intents into four categories:

Informational - a search for knowledge.

Commercial - anting to buy, rent, or sell goods or services.

Transactional - Having the intention of making a specific purchase.

Navigation - Searching for a specific website on the internet.

The search intent of the top-ranked websites influences the keyword difficulty score. Remember that search intent isn't a monochrome picture. There is a lot of ambiguity, and Google frequently returns results for various search intents, making things more difficult.

Page Authority

Google loves to rank pages from reputable websites like Wikipedia and Amazon.

Some of these sites' pages are ranked based on page authority and quality.

However, being on an authoritative domain gives most pages on authority sites a HUGE boost.

Therefore, in addition to looking at the pages you're competing against, you should consider the sites you're competing against when assessing specific keyword competition.

Results with high PA and DA are typically very competitive.

The majority of the top 10 results should have low PA and DA. You can easily rank for these keywords.

In other words, a page's high authority is crucial, but DA should also be considered.

Link Equity

The terms "domain authority" and "page authority" are not ones that Google has approved, just like the term "keyword difficulty." Depending on your product, you may also see them referred to as "domain rating" and "URL rating". Instead, they are metrics designed by SEO software providers to determine how much link equity a page or domain contains. Because of this, there will be some variation in the metrics themselves—not only from one product to the next but also in terms of how accurately they reflect the quality of the pages they are evaluating.

When considering domain and page authority, link equity is an excellent place to start. An external and internal inbound link pointing to a page contributes equally to the page's link equity.

Search Volume

The number of monthly searches for your keyword is known as search volume in SEO. The more frequently a keyword is searched, the more likely a page optimized for that keyword will bring in customers for your company. By comparing search volume to page views in Analytics, you can determine the potential traffic value of a keyword.

Content Optimization

The process of updating the on-page copy, images, links, and even the code is known as content optimization, and it is done to help search engine algorithms rank your pages higher. In the end, this makes it easier for people to find you. This is referred to as SEO content in the industry.

The more helpful content will be both user- and Google-friendly.

Targeting Keyword Difficulty Per Level

A good keyword difficulty does not exist. Before you can use it, you must first comprehend the information the score provides. Now that you know the factors that go into it let's look at what the score means for your SEO and marketing efforts.

Generally speaking, you shouldn't restrict your keyword efforts to a particular ranking difficulty level. The best approach is to use various keywords that fall into different difficulty brackets.

Low Difficulty

Targeting low-complexity keywords is preferable if you're just getting started and your site needs more content, authority, and few backlinks. Getting traffic to your content quickly at this point is essential. You have a better chance of ranking on the first page of search results and driving traffic to your website when you use low-complexity keywords.

But don't restrict your search to these keywords. The goal is to start the process and produce relevant content to the audience. You can direct some of your efforts toward creating content that targets keywords that are more challenging to rank for a while this website traffic from low-difficulty search terms is coming in.

Medium Difficulty

The key to the medium range is to make sure that the content is of the highest calibre, hyper-focused on the search intent, and properly linked.

The more effective and accurate your keyword research, the higher your chances of succeeding in ranking for these terms. When you understand precisely what your audience is looking for and how they search, these keywords can be precious.

High Difficulty

Keeping a few challenging keywords in your SEO strategy's back pocket is a good idea. Remember that climbing to the top positions on the SERP takes time. Create top-notch, timeless content that remains relevant and unrelated to current affairs. To gradually establish authority, link to your other content from this one, and keep the content updated and optimized.

Sites with solid authority, link profiles, and existing high-quality content can concentrate more on these keywords to significantly increase their organic traffic. In-depth keyword research and content optimization efforts are necessary to rank at the top of the SERP and keep it there. In addition to using capable tools, you must have the essential staff and knowledge.

Keyword Difficulty in PPC

The name of the keyword difficulty metric we're discussing, "Competition," makes it clear that keyword difficulty in PPC operates somewhat differently. In PPC, each keyword's level of competition is typically given a rank—Low, Medium, or High—which indicates how intense it is compared to all other keywords. According to Google's Keyword Planner, competition is the number of advertisers that show on each keyword relative to all keywords across Google. We estimate the proportion of advertisers placing bids on each keyword compared to all other keywords on Google. This information is particular to your chosen areas and the Search Network targeting option.
