We identify these patterns by looking at the activity of millions of web users throughout the world, and using data normalization to correct for any biases.
The more traffic a site gets, the more data we have to calculate estimated metrics.
The links on the other websites are called external link.
You should not have too much external links on your website.
There is not necessarily a link between the upstream site and this site.
The "Sites Linking In" count shows the number of sites that Alexa found that link to this site.
Audience Geography The audience geography data describes where visitors to this site over the past month are located, and how the site is ranked in popular countries. Engagement metrics help you understand how interested a site's visitors are with the site's content.
If there is no alt tag, search engine doesn't understand anything from the image.
That's why you should use alt tag on your all pictures, which you use in your website.
Estimates are more reliable the closer a site is to being ranked #1.
Global traffic ranks of 100,000 are subject to large fluctuations and should be considered rough estimates.
