Weird Spike Resolved
I think I found the answer to this weird spike. I’m pretty sure that this site sent some users there. It’s the only place I can figure out. The Best Selling Guide website was using a generic amazon tag, so I added a new one and am tracking those hits.
I think that $19 whole dollars might be enough to justify treating the other categories like the books; if you click on a genre it shows a list of best sellers if you click on a book, it takes you to a detail page, but if you click on a category and then on an item it takes you right to Amazon. If I keep some of the item info and use item detail pages it should help my keywords and searches. Since I don’t really think people are searching for best selling electronics, it should help people when they search for specific items.
And if I add RSS feeds for the categories, that’ll probably help too, with link bait.
Not that I think anyone’s searching for “best selling books” though
