What are the Top Keyword Research Techniques for SEO in 2023?


Understanding the Importance of Semantic Relevance

This article will explore some of the most effective keyword research methods being utilised in the UK market in 2023.

SEO isn’t just about incorporating keywords into your content anymore; it’s about semantic relevance. Google’s quality guidelines emphasize this, stating that websites should focus on creating content that provides a beneficial, enjoyable, and user-friendly experience.

Google uses semantic search to understand the context and intent of the user’s search query, going beyond the literal meaning of the keywords. By focusing on the relationships between words, phrases, and sentences, semantic search provides a more accurate understanding of the searcher’s intent.

SEO Keywords

AI and Predictive Search

Artificial Intelligence (AI) and machine learning are shaping the SEO landscape, especially in keyword research. The rise of AI has made Predictive Search, which uses AI algorithms to predict search queries based on the user’s browsing history, increasingly prevalent.

Predictive Search presents opportunities for SEO. By analysing trends in your target audience’s search habits, you can anticipate future queries and optimise your content accordingly. For instance, Ubersuggest is an excellent tool for trend analysis, helping you to get ahead of the curve.

Latent Semantic Indexing (LSI) Keywords

Latent Semantic Indexing (LSI) keywords are terms and phrases related to your primary keyword. These related keywords provide context, assisting Google in understanding your content’s subject matter. Using LSI keywords can improve your site’s visibility and ensure your content is semantically rich.

For instance, if your primary keyword is ‘chocolate cake,’ LSI keywords could include ‘chocolate cake recipe,’ ‘how to make a chocolate cake,’ ‘dark chocolate cake,’ and so on. Tools such as LSIGraph can help identify relevant LSI keywords for your content.

Long-tail Keywords

Despite their lower search volume, long-tail keywords are invaluable due to their specificity and less competition. They tend to have a higher conversion rate, as they cater to more precise user queries. For instance, a user searching for ‘women’s waterproof hiking boots UK’ is more likely to make a purchase than someone searching for ‘boots.’

Tools such as Ahrefs can help identify valuable long-tail keywords in your niche.

Keyword Difficulty and Search Intent

Keyword Difficulty (KD) is a vital factor to consider in keyword research. KD indicates how hard it would be to rank for a particular keyword, taking into account factors such as competition and search volume. Understanding KD can help strategise your SEO efforts and avoid battling for highly competitive keywords.

Search intent, or the reason behind a user’s search query, is also crucial. Google prioritises content that matches the user’s intent. Therefore, identifying and optimising for the four types of search intent – informational, navigational, transactional, and commercial – can significantly improve your SEO performance.

Local SEO and ‘Near Me’ Searches

With the rise of mobile searches, ‘near me’ searches have become more prevalent. As a result, Local SEO has never been more important. Local SEO involves optimising your online presence to attract more business from relevant local searches.

By including local keywords in your SEO strategy, you can tap into this trend. For example, a bakery in Birmingham might use keywords like ‘bakery in Birmingham’ or ‘best Birmingham bakery.’


Keyword research is a fundamental aspect of SEO, but it’s an aspect that’s continually evolving. To remain competitive, understanding and leveraging the latest keyword research techniques is essential. By implementing these methods in your SEO strategy, you can enhance your website’s visibility, increase traffic, and improve your overall online presence.
