Another thing to watch out for is see if someone is trying to snake your design/business model. I know in the past when I would get suspicious traffic like that I would quickly take a spin around elance/odesk/etc. and often find a competitor had posted something like 'make me a site just like (mysite.com) but cheap and scrape all their products so they're already in a database'.

If Bangladesh is nowhere near your customer base I'd do what Ryan suggests as well and block em.

Speaking personally I'm not in favor of it but more from an appearance perspective. I've seen a lot of cases where this is abused by smaller operations who aren't taking their customer's overall outbound link profiles into account. We've inherited projects where the previous designer put about 100 words into the META author tag spamming his keywords, and then in addition put at least a paragraph of ALT text on his footer link. The client didn't even know it was there, or what it necessarily meant.

I also think it detracts from the appearance/professionalism of larger clients sites. I think personally I'm moving towards either very subtle and small center-footer links, with the full knowledge of the client, or a paragraph and link on the About US/Partners page. Note this is my opinion on what we're doing and not meant as an indictment of anyone else's practices.

You're thinking about it the right way at least. Many clients come to me with "get rid of that bad listing right now!!!" and I have to respond with "I'm sorry but if I controlled the internet I wouldn't be working for you" and then they storm out and it's generally a bad scene.

All those things you mentioned are good tactics to push something down the SERP. Some others off the top of my head:

• Press Releases
• Guest Blog/Friend Blogs about the company
• Bizarrely, YouTube works sometimes if the account is co-branded
• Registering for services like Manta, TechVibes, citdirectory, macrae's, other industry directories
• Legitimate forum postings made in the company's name

There's others, but I think you get the idea.

I would agree, but not necessarily from an SEO/'Google will downgrade you' perspective. It's not exactly clear what effect the title has, though it very obviously does have an effect. However the title is often the first thing a searcher sees when they are presented with your link as a search result, which means to me that making them as 'human' readable friendly is as important as having keyword prominence. Mind you I'm coming from an ecommerce angle, where information about the product has to be communicated clearly in those 70 characters, it may be different in other categories.

As for the keyword stuffing and H1, yes those are definitely onpage elements that you should get sorted out.
