As a key strategy for businesses seeking web visibility, local SEO can be significantly improved through the intelligent use of a topical map.

Firstly, it's pivotal to understand what we mean by a 'topical map'. It's a method to organize closely related topics or keywords into a coherent structure that makes website content more navigable for users and caters to search engine algorithms.

The key to a successful topical map is understanding your audience and their common search queries. By understanding these search phrases, topical clusters can be created around keywords which increase organic traffic.

So, how do you start? Keyword research is the first thing on the agenda. Use tools like Google Keyword Planner or SEMRush to identify high-volume, low-competition keywords linked to your business or service.

Once your keyword research is complete, design topic clusters around your primary keyword for each webpage. Each secondary keyword should form its own sub-topic, all linking back to the pillar content.

The advantages of using a topical map in a local SEO strategy here are far-reaching. Because topical maps help search engine algorithms recognize the relevancy of your website content, it's more likely to increase your site's appearance in search result, thereby driving traffic.

All in all, with a well-planned topical map, you can substantially improve your local SEO and make your website significantly more accessible.
