Have you ever experienced spike in traffic when an article or two goes viral ? For you, is this a good thing and a door to expand you traffic resource ?
I like them. They give the much needed boost for low-medium traffic blogs / websites.
It is also good to learn from it. What clicked and for which topics your website can get organic traffic.
Once an article goes viral we can hang around the same topic. Hoping that Google will rank us further based on recent success. It is more of a certainty that assumption as there is something valuable in such a content which got a lot of hits.
If we can identify 4 or 5 such topics, there will be a huge advantage versus the fact that we are aiming in the dark.
