Requests for delisting

When requesting that a URL be delisted, you should give compelling evidence as to why it should be delisted. Cases of this could include (but are not limited to) hijacked domains being returned to their rightful owner or a site with content that violates copyrights cleaning up their act.

Relevant links:

• Proposed removals – Use this section to request that links be removed from the spam blacklist.

you have to give them a good reason to remove your from the blacklist, if you have been spamming the wiki, then I don't think they will remove the ban.  You have to propose the removal from the link above giving reasons why.

I can confirm chris is correct, our crappy CMS does the same thing (for certain pages), and the pages are not indexed

Our system does this and I think its a bad Idea (for us any way),  our target market is UK and Ireland.  But when google was crawling our pages they were only getting the US version of the site, so all that nice text we had for the UK and Ireland pages was was missed by google (the US page was the systems default page, with no custom text).  I just copied and pasted our UK & Ireland text to the US default page, then we started to rank for some of the targeted keywords.

Now our problem is that is google bot is getting the prices us dollers instead of Pounds or Euros so for some of our rankings it picking up meta data and showing $ prices in the serps for the UK.

So my advice is be careful, it might seem like a good idea for users, but google will only see the US version of the site

To answer you questions:

• How will Google index these pages? Will it index the www.mywebsite.com (Japan version) in its Asia archives and the www.mywebsite.com (US version) in its North American archives?

It will only index US version for all

• Will Google penalise us for showing different content across Geo-locations on the same URL?

To my knowledge no  (we used they system for 3 years and rank modestly)

• What if a URL is meant to show content only in Japan?

Not sure what you mean, but you need different urls for different content

• Are there any other issues that we should be looking out for?

See what I said above

I have seen this before, it looks like <a class="attribute-value">http://www.osce.gob.pe</a> has been hacked, but you have said that you have tried contacting them to tell them they have been hacked.  Looks like they are only showing google your scrapped content but redirecting everyone else ( its a broken redirect for me), i'm guessing the hacked site has a higher authority than your site and that is why its out ranking you.  This seems to be a common trick for these guys to make a quick buck for a few weeks before google catches on whats going on an corrects the serps.

Maybe try reporting it on googles forums, maybe a mod will escalate it for you.

Keep us updated

I was having the same problem ( for me it seemed to be Bings ads bot) .  I used this guide below and it seems to filter out most of the bot visits.

google might recognise it as an affiliate link and therefore unnatural and so reduce or remove its seo value.

I think Screaming Frog will tell you the page it found the weird url, then you can check the source, and find out whats producing that link.

ok I did a quick screaming fog and I think I have an idea, you just have to follow the breadcrumbs

You said in you example "In Links 9", you need to find out what those pages are and follow it back to the point of origin As I think its just one bad link that cause this nested link effect.

eg

http://www.odin-groep.nl/Home/ctl/OverOdin/OverOdin/OverOdin/OverOdin/HeutinkICT.aspx

is being linked from

http://www.odin-groep.nl/Home/ctl/OverOdin/OverOdin/OverOdin/StationtoStation.aspx  (as well as others)

You just have to follow that trail till you find the source of the problem

So yeah this has nothing to do with rich snippets,  goojle is just figuring the product count.  So if you look at the example size, they have the text showing "Showing 53 products"  so google has worked out that there are 53 products,  but on your site it says "showing 1 - 52 of 156",  note it does not say "products" so google not picking up the meaning  of "showing 1 - 52 of 156",  I would guess just by adding "products" to the end of that text, google will pick that up.

Just to follow up, on our site we have on categories that have more than one page it says "Showing 1 to 24 of 32 results ", and in the serps it says "Results 1 - 24 of 32"

For categories with one page , its say eg "Showing 15 Item(s)" and the serps says 15 "Item"

But for a category that has only 3 products "Showing 3 Item(s)" the serps does not show anything, so there is no guarantees that it will work.

(on a side note, I must change the way we display the number of products, "results" and "items" are not really the right terms )

First you want to decide if you want open-source vs a closed platform.  As a general rule open source need more work and at least some technical knowledge, but there are cheap/free and you have complete freedom with them.  Closed platforms are generally easier to setup and easier to maintain but are more expensive (up front costs at least) and because its closed you have little freedom ( at the mercy of the company the develops it)

Note that is a very general rule and every platform is different and there is always the argument (normally put forward from closed platforms) that open source is can be  expensive in the long term because the costs of upgrading/maintaining it, espically if you our sourcing that work out.

I have used Zen-cart alot. big bonus is its free, its got a nice community (but not huge) and its a decent platform, but can require a bit of work to get it the way you want. big negative is that it can't do stock control for products with options eg you have a shirt that comes in an option of red or black, it just tracks the shirt stock not the amounts of red and black shirts.  If you are not using it for stock control then its not an issue (as I believe they are working on a fix for this) .   Over all Zen-cart is a good start if you have a low budget.

Starting to use Magneto, and even though its also "open source" it frees alot more commercial than zen-cart, but has a far bigger community and tons of extensions.  It still need a bit of work to get setup but it alot more flexible than zencart and has more 3rd party modules. There is a reason its the biggest E-commerce system in the world.

Never used Open-cart, but I did look into it and it looks nice ( but a know of a competitor that moved from open-cart to magento enterprise)

Another one I looked at is visualsoft, people that I know use it are happy with it as is easy to use and because it a closed platform you don't have to worry about alot of the technical stuff.  The basic price for it is ok, but they really  get you with the addon and can soon add up on price (that and you don't have the freedom of opensource is the reason I did not go with them)

I'm sure there are more platforms that are just as good if not better that the ones above, but I can only tell you about the ones I have experience with
