What is irrelevant content? It is content on your website site or SEO keywords that are not related to your market, service, product or niche. You have to put your search engine hat on to understand why this is important.
Search engines index and catalog web pages based on the information they find on your website. That means text. If your content includes information or keywords not related to your business, it reduces your scoring or rating with search engines results. This poses an immediate problem, which is how your site ranks against others in search results. Another potential, unintended consequence is for your website to flagged as spam.
This poses a problem with your target market or niche as well. If someone finds your site, will they know exactly what you are about and what you are providing?
Is your website about wellness with a side of your adventures as a downhill skier or vise versa?
Is your site about market research or your weekend backpacking trips?
One way to avoid this problem is to perform SEO marketing research to understand what content your target market or users are researching, and create a list of keywords or phrases based on your research. Incorporate those keywords and phrases into the titles and content of your website. This improves your organic marketing and provides guidelines for the type of content your should create and the SEO terms you should use. Help search engines help you.
If some information seems unrelated or not appropriate to your website’s primary purpose, your site visitors may bounce.
