There are a few ways to check your blog SEO. One way is to use a tool like Google Analytics to see how many people are visiting your blog, what keywords they are using to find you, and how much traffic you are getting from those keywords.
You can also use a tool like SEMrush to see what keywords your competitors are ranking for and see where you rank. Finally, you can use a tool like Followerwonk to see how many followers you have on social media platforms and which ones.
Overall, SEO is an ongoing process that will change over time as new algorithms are released. However, checking your blog SEO regularly can help you stay on top of the competition and improve your blog’s overall visibility.
