Link from pdf file

Very little in this area is laid out experiments and practical recommendations. Or just met a little) I decided to start my series.

There are Western recommendations for nontrivial link building, namely creating a pdf booklet with useful materials and a straightforward link inside (at least site.ru) as a source.

I decided to check how much this works in our environment:

created a file:

www.dom-pereezd.ru/file_pdf.pdf
Inside the file there is an active link with the anchor "intricate extreme link"

waited for indexation:

Total:

Only Google could find the page using the link from the pdf document, and pay attention to putting it higher than the page with text matching.
