Negative link velocity
I have a site that has lost about 12 places in the serps for one of its keywords and looking at ahrefs I'm guessing it is due to losing links - a steady decrease of links over time.. Just after some advice really, looking at @ron and other guru's here. Currently building between 10-20 links per day (direct) as I wanted to keep it looking natural.. As it is taking longer and longer to index links, would you suggest to increase this? Maybe 50-60 per day? More? The site is PR1 and about 7 years old..
