While a guest post is free, a sponsored article requires a fee for the website that promotes your business. Most of the time, you provide the content, but the website can also handle that for you. In general, it's a simpler marketing strategy for your brand. A sponsored post is a post on a website or blog that is paid for by a sponsor and is seen by visitors.
Since not all guest posts were created the same way, if you're responsible for the content of your website, you need to be very smart with external posts. So yes, I'm in favor of charging a fee for sponsored posts; otherwise, it's a guest publication for a company, which isn't what you want. Guest posts can help build brand awareness among different viewers and attract new traffic to your site. Alternatively, you can simply deny the guest post request because the price is too low or because the proposed content doesn't fit your content strategy.
And sponsored publications are those types of publications that are specially aimed at promotion and improving the ranking is the second most important alternative. Guest posts are a blog post based on the requirements of a particular blogger to get backlinks in return. Posting as a guest establishes a relationship with the blogger who hosts your publication, takes advantage of their audience to gain greater exposure and helps you establish authority among the target audience. At best, the article published as a guest contains revolutionary information that comes directly from the source, a scientist with a new study, for example, that you can share with your audience directly.
You might see me break that rule from time to time, but keep in mind that any email you send me about guest posts will likely be deleted as soon as it reaches my inbox. I'll go into more detail later, but keep in mind that the weak point of the beast of sponsored posts (and guest posts) is the backlink. Deciding to accept authors of guest posts essentially frees up your publishing schedule and, at the same time, provides your readers with great content. The content of these publications varies; a sponsored post can, for example, review a product or discuss a company's offerings.
It's common to see sponsored posts combined with other forms of advertising; for advertisers, the advantage of sponsored posts is that they appear in sites' feeds, ensuring that they reach all viewers of a site, not just those who visit the main page. There's also the fact that allowing guest posts on your blog significantly increases your connections in the industry.
