We are perplexed how Yoast determines which keywords to select on the page when ranking the top 5 prominent words in Insights. For example, we have a page where birthday parties is clearly the primary keyword. It is used an an H2, in body copy and tagged on images. Yet it does not show up at all. The term 20 Fiesta game points ranks #1. It is mentioned one time on the page in a bullet within one of 5-6 blocks. 40 Fiesta game points ranks 3rd and same situation. Waterpark ranks 4th and is mentioned twice on the page as a bullet of featured activities. But there ar 4-5 other attractions listed in the bullets higher?  We have looked as tutorial videos and no one mentions how Yoast determines prominent keywords. Thanks in advance for steering us in the right direction.

We have a client who once per month is being hit by easyihts4u.com and it is creating huge increases in their referrals. All the hits go to one page specifically. From the research we have done, this site and others like it, are not spam bots. We cannot understand how they choose sites to target and what good it does for them, or our client to have hits all on one days to one page? We created a filter in analytics to create what we think is a more accurate reflection of traffic. Should be block them at the server level as well?
