I'm not an expert but for a time I helped my brother out who owns a number of websites -- some similar to this one. Imo, it's just silly article to begin with. Substitute any theme for Ideas and it's all the same. "Lego Ideas set have become larger and more expensive". There's the whole article -- nothing else said adds to it. Now how can that be expanded to 1500 - 2000 words, insert graphs, pics, links to other articles, repeat key words, make searchable headlines throughout . . . -- affiliate links. From my understanding it's not really an effective webpage to do any more because Google changes up its analytics so much. Again, I'm not an expert but when I started reading it it just hit me with being a shallow article that just strove to hit all the right metics for search results -- although dated in its approach.
