The choice of tool depends on your tasks and budget. Often, using a combination of tools gives the best result.

Keywords are divided into several types:

Commercial (transactional) queries are aimed at encouraging action, for example, “buy a smartphone”, “order food”.
Informational ones are used to search for information: “how to choose a bike”, “what is SEO”.
Keywords are also classified by purpose:

Navigational – to find a specific site or page, for example, “login to your Google account”;
Branded – contain the brand name, for example “Apple iPhone”;
Generalized – broad queries such as “smartphone”, “car”;
Geo-dependent queries – take into account the user’s location, for example, “buy an apartment in Moscow”;
Seasonal – popular at a certain time of year, for example, “New Year gifts”;
Flashing – temporary queries that are losing relevance, for example “Olympics 2024”;

Types of frequencies according to Wordstat.jpeg

Search volume shows how often users enter specific queries, which helps to assess the potential of a keyword in an advertising or SEO campaign.

Yandex Wordstat classifies the frequency of keywords, initially shows the basic frequency, but there are others.

Base frequency
Base frequency is the total volume of queries for a keyword, without taking into account the word order or additional specifications. This is the most general indicator, which does not give a complete picture of the use of the keyword, but helps to understand the general interest in the topic.

Phrase frequency
The refined frequency takes into account only those queries that contain words from the key phrase, taken in quotation marks. The word order may vary  things to consider when translating subtitles and the endings of these words may differ. In Yandex Wordstat, such queries are enclosed in quotation marks.

Example: “buy a bicycle”.

Accurate frequency
Same as phrasal, only endings in words are also taken into account. In Wordstat . Such queries are processed using exclamation marks before each word and quotation marks. This helps to estimate how often users search for specific phrases in a given form. Keywords in SEO and PPC Advertising: From Basics to Advanced Strategies

Example: “!buy !a bicycle”.

Specified frequency

Very precise frequency covers queries where keywords are not only used in a precise form, but also in a precise order. In Wordstat, such queries are enclosed in square brackets and contain exclamation marks before each word. This allows for the most accurate determination of the actual popularity of a query.

Example: [“!buy !a !children’s bicycle”].

Keyword Effectiveness Index (KEI)
As a bonus, let’s look at the Keyword Effectiveness Index (KEI).

There are several popular formulas for calculating KEI:

KEI = (1000*P^2/C), where P is the number of direct queries per day, and C is the total number of pages for this query in the search engine index.
KEI = ((Frequency + [!refined !frequency]) / (frequency + 0.01) – 1) * 100.
In simple terms, KEI calculates the  by lists balance between competition and demand. In the first formula, competition is determined by the total number of pages, and in the second, by the base frequency. Demand, in turn, reflects the frequency of requests.

Types of CS by frequency of use

High-frequency (HF) : High search volume, high competition. Example: “buy a phone”. High-frequency queries can be more than 1000 queries per month.
Mid-frequency (MF) : Mid-frequency queries are the golden mean between volume and competition. Example: “buy a smartphone for up to 30,000 rubles.” The frequency of use of such queries can be from 100 to 1000 times per month.
Low-frequency (LF) : Low search volume, but high conversion. Low-frequency queries are, for example, phrases such as “buy iPhone 13 Pro Max 256GB green”. The frequency of use can be from 1 to 100 queries per month.
By level of competition
Highly competitive : Difficult to rank for, but potentially high traffic. Often these are general queries in popular niches.
These words have a limited number of sites that are already optimized for them. They are usually less popular queries or more specific phrases. Examples include localize queries or niche topics.
Advantages: easier to get high positions in search results, lower advertising costs.
Medium competitive : Optimal balance between difficulty of promotion and potential traffic.
This category includes queries for which a significant number of sites have already been optimize, but there is an opportunity to take competitive positions. These words are often more general terms that are not as specific.
Advantages: provide good traffic, but require additional effort to achieve high positions.
Low competition : Easier to promote, but usually less traffic. Often these are highly specialize or local queries.

The Evolution of the Role of Keywords

With the development of technology and search algorithms, the role of keywords in SEO has undergone significant changes. In particular, the introduction of voice search and artificial intelligence (AI) algorithms has changed the approaches to the selection and use of keywords.

The Impact of Voice Search
Voice search is becoming increasingly popular. According to research, in 2024, about 55% of users used voice search at least once. This figure is predicte to reach 70% by 2025.

This affects the structure of queries:

Longer, more conversational phrases
Interrogative forms of queries
Taking into account the user’s context and location
Artificial Intelligence and Semantic Search
Modern search engines use AI (transformers) to better understand the context and intent of the user by evaluating the semantic (meaningful) relationships between words.

Google BERT analyzes the context of words in a query
