Keyword Difficulty Analysis: How to Choose the right SEO keywords

A successful SEO campaign almost always relies on the keywords used. As elements that search strings are matched against, they can propel a website forward, helping it rank on search engines. The significance of individual keywords, however, is slowly dwindling, and keyword-based search engine optimization is losing its strength. Blame it on black hat practices that, even when they're being cracked down, have left lasting effects. This is because there are now factors that are far more important than keyword presence:

• Keyword placement matters more than usage frequency. That is, using keywords in the title tag and header has more weight than using them five times in the content.

• Using synonyms is more than acceptable. Now that Google is more sophisticated in interpreting data of a website, keyword specificity is fading. So even if different key phrases are used, as long as they have similar context, Google can place them in the exact same category, theoretically.

• Semantic search is making a huge difference on user searches. In the past, Google dissects search queries by words. A search query about "running shoes Utah", for example, would return anything that may be related with running, shoes and even events in Utah. But with search semantics, Google interprets the meaning of the whole search query rather than just the individual words.

Along with these changes is the need to take a different approach to keyword research. Keywords still matter, but they need to be perfect to be really effective. So whatever process you have been following for as long as you can remember, you should completely forget. Even if you did rank, it turns out that you have been doing keyword research all wrong. Rather than research for high volume, low competition and good CPC keyword, or effective latent semantic index keywords, you should use keyword difficulty analysis instead.

What does Keyword Difficulty Analysis mean?

keyword difficulty analysis

Keyword difficulty is defined as a factor that helps determine how easy or difficult it is for a website to rank based on a particular keyword. So it's no longer about short-tail or long-tail, and high or low, because other factors now come into play, such as the following:

- The number of pages currently ranking for a specific keyword
- The number of pages bidding on a keyword in paid search campaigns
- The volume and cost per click of a keyword for a particular month

If you want to go down to specifics, you also need to look into queries that you must compete for based on three elements:

1. Your competition or the number of indexed pages for a particular query
2. The authority or ranking strength of a website based on the quantity and quality of incoming links
3. The relevance of well-ranking websites in terms of how they match certain search queries with consideration to factors, such as on-page ranking and off-page signals.

Difficulty analysis also entails estimating keyword difficulty. The easiest way to do this is to check out strong and weak search results based on a keyword or key phrase that is widely used. Between "running shoes Utah" and "Nike running shoes", the latter is harder to rank with, especially for normal and less-popular blogs. There is no way you can compete with high authority blogs.

A search query on "Pebble Time review" would return the following results:

All of these make up the top 10 strong results, which is clearly hard to outrank by less authoritative websites.

But if you use long-tail keywords, there is a possibility that the results will include forums, non-relevant sites, YouTube videos, Yahoo Answers and other websites that will be easier to outrank or those that make up weak results. So, what you want is a keyword that will return weak search results.

But because there are no hard-and-fast rules in difficulty analysis, you need to use tools at your disposal. A keyword difficulty tool can come in many shapes and sizes, so to speak. It's not just a specific type of software, but a set of procedures that lets you identify keyword difficulty.

Perform difficulty analysis based on several principles

Competing Pages

Find out who your competitions are for a particular keyword or phrase. Simply type in the search terms you want to use on a search engine and check out the results. As a blog or a business, your competitors are other blogs or companies that are providing the same products or services, and using the same set of keywords. The top ten is your strongest competition.

You can further narrow down your search by looking into the number of pages being indexed that use the same search terms on the title. To do this, use one of Google's advanced search operator "allintitle", which will display websites where the keywords appear in the title.

Now that you know your competitors, it is important that you don’t make any decisions based solely on the data that you collected. Just use them as an indicator, since there are plenty of other elements that will keep you off the first page.

Top 10 Search Results

If you want to determine the metrics involved in keyword difficulty, determine the top ranking sites related to the terms you intend to use. Getting results is easy. It is making the searches non-personalized that is challenging, although not impossible. You just need to use the right tools to de-personalize your search and get the results that matter more. Using Chrome browser in incognito mode is one good example. What this does is to remove results returned based on search data and preferences, such as ads, news, images and YouTube videos.

Number of Links

Top-ranking pages are likely to have a significant number of external and domains pointing links based on certain key terms. If you use the same keywords, you would definitely have a hard time ranking. But if there is a top-ranking website with just a few direct links, you have a door of opportunity. Using Open Site Explorer or Majestic SEO, you can acquire a number of linking domains a website has. But know that a site with few high quality links can have the same authority as one with plenty of low quality links, which is why further analysis is necessary.

Off-Page Optimization

How strong a competitor website's off-page optimization is reflected on the number, authority and type of links it has, including the backlinks. Keyword difficulty analysis will look into page authority, domain authority, keyword in anchor text and the diversity of unique linking root domain.

On-Page Optimization

Now that you know who your competitors are, find out how well optimized they are. Think like a search engine and look for different signals that will help your keywords rank easily and effectively. 

      • Keyword in title tag
      • Length of the title tag
      • Keyword in H1
      • Keyword in image alt text
      • Keyword in domain or URL
      • Keyword representation in anchor text or external links
      • Content quality
      • Optimization level (over optimized or not)
      • Use of questionable SEO practices
      • Internal linking architecture of a website

You can also keep your evaluation simple by just ranking each page's optimization as none, minimal, over, fair, decent or good, and excellent. Regardless of which step you take, however, this process takes a lot of work. If you want to cut down on the amount of effort and time you spend, you should filter your keyword list to a manageable size.

Perform difficult analysis using Google search operators 

Google can be your best friend in difficulty analysis, and not just in knowing your competitions or the keywords they use. To maximize Google, however, you must use three of its special operators.

As already mentioned, allintitle returns results that contain your search terms on the title. allinurl, on the other hand display results with the keyword included in the URLs, and allintext returns search results with the keyword appearing within the content.

How do you use them to your advantage? Using the keywords "nike running shoes", for example, run a keyword difficulty analysis in Chrome. Don't forget to search in incognito mode to keep results organic and non-personalized. Take note of the total results and those that returned using Google's advanced search tools. The data you collect will look similar to the one below:

Keyword: nike running shoes

keyword difficulty analysis for total results

Results with allintext: nike running shoes

keyword difficulty analysis for results with allintext

Results with allinurl: nike running shoes

keyword difficulty analysis for results with allinurl

Results with allintitle: nike running shoes

keyword difficulty analysis for results with allintitle

What do the figures tell you?

• If the total results are equal or close to 1,000,000, you have higher chances of ranking on the first page.
• If the results with allintext are just 50% more than the total results, keyword difficulty is very high.
• If the results with allinurl and results with allintitle is less or close to 1,000, the chances of ranking on the first page is high provided that certain criteria are met:

      o 2000+ words in-depth blog post
      o Proper image optimization
      o High Flesch Reading Score
      o Quick Load Spee
      o Good Social Shares
      o Efficient Inter Linking
      o Several high DA, PA Backlinks
      o Perform difficulty analysis using specialized checker

What is great about using Google search operators is that you will know your competitors during your research. But you can always take a shortcut through a keyword difficulty tool.

Originally a professional SEO tool designed for digital marketers, SEMrush has recently introduced a tool for keyword difficulty analysis where you can bulk check ranking of multiple keywords. It is not free, but you do get a 14-day free trial period. Look for the keyword difficulty analyzer under Tools, type in your keywords and then search for their difficulty score. You can put in a maximum of 100 search terms per line.

The great thing about this tool is that you get more in one go. That is, you not only learn about Keyword difficulty, but also Keyword Research, Competitors Analysis, and even Backlink Opportunities.

Keyword difficulty analysis can be done for app store optimization as well. Check out the result count to determine the number of apps targeting a particular keyword. Simply type in the search terms on the app store and both Apple and Google will show which apps use certain keywords. Another factor is volatility that provides a good indicator of how difficult it is to rank for a particular search term. Because finding volatility manually is hard, look for tools that you can use.

Once you have a list of keywords, sort and filter them out into different categories, such as immediate and short-term keyword targets, medium-term keyword targets that need to be groomed and grown, and long-term keyword targets that can be obtained through sustained effort.

Keyword difficulty analysis may seem like a new concept, but it is the new way of ranking in search engine results, which is why it is worth implementing in your SEO campaign.
