Do I even bother to remove links

[McTaggart]

Hi,

I'm noticing increasing numbers of scraped directory links pointing back to the websites I manage. Much of this info appears to be scraped from a well known (and respected) directory.

I don't build links to an of the websites I manage - and none have more than 200 linking root domains currently - not that many.

The problem is I focus on quality links and the scraped links are incredibly weak on the whole. Diluting the quality links.

I've noticed a certain paranoia in the SEO community about removing / disavowing links, and yet I'm tempted to ignore the rubbish (unless part of a major negative SEO push) and just get on with the job, focusing on quality content that drives natural links, and social media work.

Thanks for your useful response. Yes, I'm thinking it's a numbers game. If a company goes very aggressively after ad links or directory links (and even less obvious types of  link - too much blogger outreach, for example) I guess they're asking for trouble.

To be honest, I don't even tell people what back-linking anchor text I want either, from journalists or bloggers for example. I just let everything flow naturally. I feel far more comfortable that way.

As long as the low quality links are relatively low then I wouldn't worry about it. It is natural to have some spammy sites that link to you. Google probably ignores these sites. These spammy sites probably wouldn't respond to a link removal request anyways.

In the case of sites that are not adding the no-follow to advertisements, the most likely scenario according to Matt Cutts videos I have seen is that Google would disable or reduce that site's ability to pass Page Rank. The links therefore wouldn't help you but shouldn't hurt you either.

The other thing I'm finding is advertizers just don't understand the purpose of nofollow - and are not using the tag very widely in the UK at least.

For example, I've just been looking at a tourism sector website. 80% of their links (140) are directory and advertizing links - some generic and some specific to the tourism industry - a half-half split.  Only around 10% of these directories/advertizements are using nofollow links.

I guess I SHOULD contact every single one and ask for a nofollow (which will NOT be easy - I've tried it - you get a lot of confused responses I can tell ya!) on the advertizing links anyway, but again... is this time well spent. And if competitors in the same industry have a similar backlink profile (which they do, locally at least), does it really matter!
