jacar.es is a site of Jacar Systems S.L. (brand “JACAR”). This page explains how the site is funded and how we label the links and content Jacar can be paid for. Article 20 of Spanish Law 34/2002 (LSSI-CE) requires this for commercial communications.
Affiliate links
Some articles may link to a product through its affiliate program. If you buy or sign up through one of those links, the seller pays Jacar a commission. You pay the same price as without the link.
- An article with affiliate links says so at the start, before the text, with an “Affiliate links” notice.
- Every affiliate link has the
rel="sponsored"attribute, which tells search engines it is a commercial link and not an editorial citation.
What we link to, and in what order
- We only link to products we have used and tested in an article or a lab on this site.
- The commission does not decide what we recommend or in what order. When we compare products, we rank them by technical criteria that the article itself explains.
Programs we take part in
Today Jacar takes part in no affiliate program, and the site has no affiliate links. When we join one, it will be listed here.
Sponsored content
Jacar does not sell links, guest posts or mentions inside published articles. It may publish an article or a lab sponsored by a vendor, on three conditions:
- We write and test it ourselves. The sponsor can review the technical facts, but not the opinion.
- The text has a “Sponsored” label at the top, and links to the sponsor have
rel="sponsored". - If the product fails the test, it is not published.
Advertising
The site shows no ads.
