NoFollow & Directory Scraper Backlinks
-
I was wondering how important it was to remove/disavow:
- NoFollow backlinks - many ("buy viagra" etc).
- Directory backlinks - many questionable/generic directories.
Obviously the focus is the equity passing links but both of the above constitute a significant proportion of backlinks to the site - I've seen that "scrapers" are seen as natural and obviously NoFollow do not pass link juice - but does the sheer number have a bearing and therefore make them equally important to address?
Thanks in advance for your responses.
Regards

If you've got viagra spam pointing at your site you likely won't be able to remove them. So should you disavow? Disavowing a nofollowed link won't accomplish anything as disavowing is simply asking Google not to count the link and a nofollow link is already not being counted. However, when you have loads of nofollowed links from spam attacks this is one situation where I often do go ahead and disavow these. The reason for this is that one tactic that spammers can use is to point a bunch of nofollowed links at a site and then one day turn them all to followed. If you've got them disavowed then you've got that covered.
Also, if you have viagra links pointing to your site, make sure you don't have a hack within your site. Try doing a google search for site:yourdomain.com viagra and see what comes up.
For directories, I don't worry about things like dmoz scrapers and 100searchengines and stuff like that, unless somehow you managed to sneak a keyword anchored link into dmoz. I wrote a thorough article on my thought process for auditing directory links here:

Regardless of the nofollow attribute, having spammy links in your link portfolio can hurt your SEO and cause a penalty. If you've identified links that are clearly on spammy site, proactively dissavow those links. Don't think that just because they have a nofollow attribute that your site is safe from penalty, because they are not.
Edited for directories - it all goes back to the quality of the link and website linking. If the directory is legitimate and useful to users, then consider it a good link. If the directory is a hodgepodge of links that was only generated to be a link farm, then get rid of it before it does you harm, because it isn't doing you any good.

Web 2.0 Backlinks
Hi Normal Web 2.0 websites like Wordpress.com, blogger.com have very High DA and PA. But when we create a subdomain, DA and PA falls to 1 as Google treats subdomain as new websites. Does it make any sense then to get backlinks from web 2.0 websites? will it help in Google rankings?

Spammy no follow backlinks - what should I do?
There is a individual/company that is creating lots of spam sites in my niche. It doesn't seem that they are trying to rank for any keywords, so I'm a little confused as to their purpose, but here's what they're doing. They scrape the top 10 Google results for each keyword and create a page - so if the niche is "widgets", they scrape the top 10 ranked sites for 'widgets', 'blue widgets', 'red widgets', and so on. A 'results' page is created for each keyword, which is linked from a home page. The results page always contains 10 websites - text is the site metadescription or similar. Each website gets a nofollow link back with the page title used as the anchor text. The host sites all have the keyword in the domain name - e.g www.widgetsxyz.com. The sites are thrown together but interestingly have a very crappy but individual logo (like 90's clipart). The host sites all have high DA/PA due to some very extensive link spam pointing to the sites, with very targeted keywords. There is seemingly no purpose to these sites that I can see - no other 'followed' links on the page or site. Whoever is doing this is churning out tens, if not hundreds of these sites. Any ideas what might be going on here, and whether I should be disavowing these sites (even though no follow). The fear is that they could switch the links to do follow, and get all the major players penalised in one fell swoop. ???

Do backlinks which contain parameters pass value
For some of our partners, we use our own tracking string in the url i.e. www.mysite.com/landingpage.html?partner=123456 . This has caused backlinks to be created to our site containing the partner string. I was wondering if these links would pass value to www.mysite.com/landingpage.html and the tracking parameters would be ignored or would Google treat www.mysite.com/landingpage.html?partner=123456 as its own page. If it did treat it as a seperate page, could you reclaim some of it using the canoncial tag?
