I write contents which basically are connected to one another. My readers need to visit all or some of them when necessary. Under each article, I have to provide 11 links all the time. I usually put them in html table, but recently, it started to look "ancient" and "boring" to me. I experimented with image buttons and found them to be toxic for seo. I went back to tables, but on some pages, I am experimenting with both traditional and css buttons. I am not able to say whether they are hurting my seo. The traffic and ranking haven't changed. I am not sure what will happen, but I have been reading that buttons are bad for such linking. Can anyone shed some light over it? I am lost.
