Cliff notes: Do what you’re suppose to do and you’ll be fine. Produce rich original content and rise to glory, fill your pages with spam (ads) and copy/paste material and it will fall from existence.
Google makes hundreds of algorithm changes every year to its search engine and this one seems to be big enough for them to blog about, although it says it only affects 1% of global search. With this change, Google improves user experience and at the same time, assists in wiping away some Black Hat SEO tactics.
What it’s suppose to do:
From the official blog post, “If you click on a website and the part of the website you see first either doesn’t have a lot of visible content above-the-fold or dedicates a large fraction of the site’s initial screen real estate to ads, that’s not a very good user experience. Such sites may not rank as highly going forward.”
If you’re more of a visual person, this is what the algorithm change does:
Who it will affect:
This update mainly targets websites whose ads above the fold far outweigh the desired content. Unfortunately for many people that relied on using Adsense and having a unique domain name that matches typical customer searches in order for higher click through rate (CTR); this is no more. Now people who rely on Adsense revenue must search for alternative means.
If you believe it will affect you and you’ve made adjustments, how long will it take Google to recrawl my website:
Typically this process can take several weeks. The amount of time it takes varies depending on how friendly your site is to the Googlebot and many other factors.
