Link Value Factors – The Experts Have Their Say

Posted by @ 2:39 am

With all the controversy surrounding linking at the moment, it was timely that someone put the link debate into context. Wiep Knol, a manager of Link Marketing from the Netherlands, has paneled 17 SEO and link building experts to draft an important list of Link Quality Factors.

The panel was provided with just under 40 different link characteristics to rate – which they did on various 5 point scales. Some were general link factors, some on-page elements, some on-domain factors and some negative considerations (dampening factors).

The surveying was based on the premise that search engines judge links for traffic (not just PR juice) and opinions rated accordingly. Below are the ratings as the experts voted. For the ful run-down of each experts opinions on each – visit Wiep’s blog for a full review (worth the read).

For anyone who ever thought effective link building was easy – think again. The list above highlights the myriad of factors that are at play. More importantly it shows that link building is a highly involved process that won’t necessarily generate top results overnight.

Thanks to Wiep for undertaking the survey and bringing focus back to the important factors behind link quality.
