Google converts many document formats to HTML and indexes them as they would any other page. This means that they count links in these documents. I don’t believe that any SEO tool currently indexes these links, but we probably should. I think that one day we will, but I’m also concerned that the effort and resources required for this won’t be worth it. According to Google Webmaster Trends Analyst John Mueller, links in PDFs don’t have any practical effect in web search.
The workload like this whatsapp number list allows both the vendor and the affiliate to focus on. Clicks are the number of clicks coming to your website’s URL from organic search results.
Links in iframes
Iframes allow another page to show inside of a page. Because of this, Ahrefs doesn’t count links in iframes. However, they are shown to users, so other tools may count them even though the content technically belongs to a different page. Google may or may not count these links.
Links from pages not indexed
We drop these links. There are mixed messages from Google representatives on whether they use these in link calculations or not. Different tools may make different decisions.
Same links from multiple IPs
One fun fact about the web is that sites may serve the same page from multiple IP addresses. If this is the case, a link index may count the same link multiple times. We don’t do this. We associate links with the pages they are on.
Multiple links to the same page from a single page
Currently, we only record one version of a link on a page. If you link to a page in the menu and then again in the body content, we will only count one of these links. We may change this in the future to give users more data, but this is the current state. Google will count all versions of links for passing PageRank but may only use one version’s anchor text.
