How to create a semantic core yourself

12/17/2023


One of the pillars of successful website promotion in the English-speaking web is a high-quality semantic core. It is created during the development stage of a web project and serves as the basis for forming the correct structure and writing relevant content. However, merely having a set of target keywords is not enough; it is equally important to conduct their clustering. This can be done manually through several methods or with the help of online services.

Primary Methods of Clustering

1. Logical Grouping

  • Objective: Analyze each keyword to understand its usage logic from the audience’s perspective.
  • Implementation: Based on identified intent, categorize search queries into groups. Pages on the website and content are then created for each group. This method is labor-intensive but suitable for smaller semantic cores.

2. Topical Grouping

  • Objective: Analyze competitors’ top-ranking pages for a few primary keywords.
  • Implementation: Use these pages as a foundation to select additional queries, forming a cluster. Synonymous keywords can also be added. This results in more thoughtful and high-quality content that aligns with user queries.

3. Semantic Similarity Grouping

  • Objective: Utilize specialized formulas and neural networks.
  • Implementation: Create high-quality clusters that include high-impact keywords and semantically related additional search queries. However, this method is labor-intensive and requires substantial experience from an SEO specialist.

Variations of Topical Grouping

Among the listed clustering methods, topical grouping is most commonly used in Western website promotion. It can be conducted in three ways:

  1. Soft:
    • Take a high-frequency keyword and add related secondary phrases.
    • Suitable for sites with a smaller semantic scope, aiming to attract traffic for a large number of search queries.
  2. Middle:
    • Group keywords based on their connection with other queries across 4–5 adjacent URLs.
    • If phrases do not intersect, they are assigned to different clusters.
  3. Hard:
    • Set a threshold for intersections with keywords from the group (typically 3 URLs).
    • Exclude phrases that do not meet this value, allowing the creation of landing pages with maximum relevance. However, the content may contain fewer keywords.

Online Services for Clustering

While manual clustering is possible, it is a time-consuming process. Experienced SEO specialists often use online services for efficient and quality keyword distribution. Here are popular services for clustering a semantic core:

  1. Keyword Grouper:
    • Used for searching and grouping keywords for both organic and paid site promotion.
  2. Local Marketing Source:
    • Assists in finding queries on specific sites, allowing customization by theme, region, and city.
  3. Internet Marketing Ninjas:
    • Offers various tools for webmasters and SEO specialists. Helps select keywords for the core and cluster them in different ways.
  4. Advanced Find and Replace:
    • An intelligent online service that effectively selects keywords, extracts queries from competitor URLs, and groups them into clusters.

It’s important to note that many online services are not free, and some have query processing limits. Exceeding these limits may require payment for processing each keyword. Some sites offer a free trial for 10–15 days, allowing clustering for free during this period before suggesting a subscription purchase.

Conclusion

Semantic core clustering is a crucial and necessary process for effective website promotion in the English-speaking web. However, manual keyword grouping is not mandatory; specialized online services can streamline the process. After obtaining clusters from these services, a final check should be performed to ensure accuracy and relevance.
