Recently I have been getting loads of dofollow links and very few nofollow links. One of my latest projects had about 5K dofollow links and only 300 nofollow links. The site ranked high on Google for few days and then dropped to 10th page. I am not saying that very few nofollow links might be the reason but it can be as well. My settings are good and I havent checked the option that allows you to create only dofollow links. I am using SER engines and checking almost all boxes on where to submit.
