Bolding keywords in articles can be a good idea as it can help to draw attention to important information and make it easier for readers to scan the text quickly. It can also help with SEO as search engines may give more weight to keywords that are bolded. However, it is important to use this technique sparingly, as overuse can make the text appear cluttered and difficult to read. It's also good to use different types of formatting techniques like italics, underline, headings and subheadings to make the text more visually appealing and easier to read.
