Welcome to the Q&A Forum

I've been checking out competitors through the 'link intersect function in my Moz account. Many have got nofollow links from high DA websites. I understand that nofollow links do not count count as a backlink, but will they add towards the trust factor?

So, when I gain a link I always check to see if the page that is linking is in the Google cache.

I've noticed recently that more and more pages are actually not showing up in Google's cache, yet still appear in search results. I did read an article from someone whoo works at Google a few weeks back that there is sometimes an error with the cache and occasionally the cache will not display.

This week, my own website isn't showing up in the cache yet I'm still ranking in SERP's. I'm not worried about it, mostly whitehat, but has there been any indication that Google are phasing out the ability to check cache's of websites?

Hi guys.

So I know external linking is good, as I've seem to have read every article written on the subject from 2007 to 2016, but can't seem to find anything more recent, but does that mean you are better to at least one external link on every page?

And if so, would it suffice to link just to our social media profiles even if you are in an industry where social media brings in very little in the way of customer enquiries? I've actually linked to all our social profiles but made them nofollow.

However, that said, would it be better to leave them nofollow and link to Government white papers in my sector for example?
