Like Quantcast, the Google Display Planner also features precise figures and information – although, once again, this website traffic checker only provides estimates. Access is free of charge and there are no additional fee-paying functions, letting you check as many websites as you want. The Google Display Planner provides all the important data you need to quickly analyze foreign websites.
However, the tool is often criticized for only being able to deliver data on a limited number of websites. This is due to how Quantcast works: website operators first need to set up a data collection feed on their website so that Quantcast can collect data and estimate traffic from then on. If a page doesn’t work, the tool cannot display matching results. Because of this, Quantcast only really offers data on large, well-known websites.
I don’t think I have ever seen or heard this explained in a more easy to read and understand format. If more bloggers or website owners understood this (and believed it because it’s the truth) a lot more would have success in the online space. Most people have their own preconceived ideas and are pretty tough to move off of them and then wonder why they never find real success online.
Not all web traffic is welcomed. Some companies offer advertising schemes that, in return for increased web traffic (visitors), pay for screen space on the site. There is also "fake traffic", which is bot traffic generated by a third party. This type of traffic can damage a website's reputation, its visibility on Google, and overall domain authority.
