This is one of the biggest issues I see with ecommerce sites these days. Automatic feeds of data, titles, descriptions, product info, etc. right into the store. It never ranks all that well without massive authority.

To be honest, the more you can change pre-import the better. Add something to the titles, change them up manually with an intern - whatever it takes to create unique value. For a while I was outranking Polyvore, David Jones & Amazon for the word "skirt" just because my product and category descriptions were massively different than anything on Google at the time (longer, more detailed, more useful.)

In this type of situation, don't be afraid to experiment. You're not going to outrank eBay, Amazon or the OEM for most products individually but if you try mixing things up you may find weaknesses that are easy enough to exploit. Whenever I imported, I'd alter the CSV files directly and then import. Made life so much better (and drastically improves rankings on long tail searches.)

(A small, small e-tailer won't do this but a mid size to large one always should be.)

You will have to keep an eye on it. The more searches are done on the YP sites, the more these links build and over time they do work against you. I agree with everyone else that they shouldn't but the reality is, we've seen them in penalty notices. Google thinks 4000 links coming from yp.com.au, yp.net.au, yellowpages.com.au and yellowpages.net.au are spammy, nofollow or not.

Jason Mun had the same issue: http://jasonmun.com/links-yellowpages-unnatural-according-google/

It's interesting to note that he's also referring to the AU version of Yellow Pages even though we've seen it with the .coms as well.

Anyhoo - I would leave it for now. Just keep an eye on it to make sure it doesn't become a bigger problem.

Edit to add: it does depend on your ad itself - don't use any links within the page. And be careful with how many you let this build to.

You may need to dig but they do exist.  For instance, I just ran an OpenSIteExplorer on vip pleasure girls - #2 local result.

They have a link from

• 81 DA, 73 PA - openadultdirectory.com/escorts/UK/  (Your highest DA on Moz is 68 so I'm assuming you aren't on this site.)

I'm not suggesting YOU blog spam but this is also helping them rank:

• 77 PA, 87 DA http://www.patheos.com/blogs/ comment links.
• They have a profile on PureVolumne that has a profile link and info about their service.
• 55 PA, 57 DA on http://www.escort-directory.eu/Escorts/UK/Escorts-London.htm

I don't want to do all the work for you but run an OSE search for erotic city life's domain (D on local).  They have a LOT of directory listings,  www.yourescortguide.co.uk/,  www.cherrygirls.co.uk/london_escort_agencies.html and a bunch of others.

Finally, you may need to do a bit more building.  Build some micosites, get some basic links into those, forward along the juice.  It's not necessarily white hat but your industry isn't necessarily going to lend itself to pure white hat SEO the way many of us can do it for our clients.  I don't usually advocate anything other than white hat SEO but realistically you have unclothed women and theoretically "paying for a woman" to advertise. It may not be a typical scenario.

Regarding paid directories: if you're talking about stuff with 73 PA, 81 DA, it's probably not that site that is hurting you.  They rank very highly.  Google returns "relevant" results - if you're on a related site, that's one thing.  Being on "every" directory that will accept you is another.

Whenever you don't give us a specific domain to help on, you have to give as much info as possible.  On the .com, after you disavowed did you build new authority or just assume the disavow would be enough? (It's not.)  On the .com you said you lost traffic January 2013 which is Panda, not Penguin.  So you were probably doing a whole lot of link cleanup to solve a problem you can't solve with link cleanup.

Given the other domain isn't ranking either, I'd guess you have some sort of Panda (content) issue. Duplicate content, repetitious & spammy titles, huge keyword stuffed meta keywords tags, thin or non-existent content, etc.  Without seeing the site itself it's hard to say but this all reeks of Panda.

As to the questions:

1. No, it's not the domain name being similar.  Without knowing the domains hard to say about 301.

2. Definitely not.

I would most definitely write it out as inch & inches and even in. when necessary.

A simple Google search for intitle:48" will show you that Google ignores the inch mark on this search.

Another search of intitle:" shows no results.

Any search I can find using "inches" does not return a result with " in the title.A simple search for most keywords with synonyms or alternate versions shows the synonym or alt version in at least some pages. Inches does not.

(Dinner shows dinner, dining & diner. Autos shows results for cars. Inches does not show " and a search for 10" shows results for 10, not "10 inches")

So yes, I would use the full words in this case.
