I have not had any issues with my clients. We send the product through with hashes like http://neat42.com/tshirts/1-faded-short-sleeve-tshirts.html#/color-blue and canonical all of the pages without the hash. If you can control the quantty through a url string you will not have any issues.

This might help.

I think Yelp does work in a positive way a lot, I know many businesses it has helped, but at the same time I think once you get to know the system you realize it is rigged. Maybe it is on purpose, or maybe it is like the early days of Google before the algorithm was perfected, I don't honestly know.

It is interesting how they do their moderation though, I figured you would still be able to see everything, just the post would be hidden from the public view.

My best course of action would be to take it to social media, maybe a few posts / tweets yelps way might get them to respond.

I personally would use both. They way that I look at it with the OG tags is that you are controlling the consistency of the brand across platforms that you do not officially support. This is very much in my mind the same thing as making a page display correctly in older version of IE.

I cross posted this thread to reddit to get the hive mind opinion on the situation. A couple of people did mention a great point, you violated Yelp's TOS by posting multiple reviews on the same company / situation.

I would say it is not good practice. I think of the heading system as a structure system. Like a book or an outline. The h1 tag should be the title that encompasses the whole page. The h2 tags are like the chapters, h3 are sub chapters or strong points inside the chapters and so on.

More than likely the reason it was removed is that it was considered spam. One way that Yelp detects spam is from new accounts that open and leave one review to never be logged into again. I went round and round with this, because /i actually ran a promotion where /i gave people a discount to leave a review. It was basically wasted money.

I agree with Keri. This in my opinion is a horrible strategy. There are only a few times I would recommend something like this and your case is not one of them.

The times I would recommend this is if your products are broad enough to support a whole site. For example I have a client that sells medical needs such as scooters, lift chairs, bathroom accessories, wheelchairs, and things like that. We did make him another site to focus specifically on scooters, just because it is a hot market. But at the same time going into this I advised him of how much work it would take. Rewriting all of the content for the descriptions, and everything else on the site.

I mentioned before that I have read a couple of your posts. One of the biggest things that I would advise for you is to work on marketing along with SEO. If I were you, I would post to craigslist every day, when you have dogs available. This does absolutely nothing for your SEO, but lets be honest, you want to move dogs, you don't want people to just come and read your site. I am sure this is no secret, but the time that I have found to post to craigslist is about 8:50 in the morning. It takes about 10-15 minutes for your post to become live on CL, so your post will show up shortly after 9. This means it will be one of the first posts that people will see. See the theory that I use, and it works with most businesses is that workers come in and screw around in the morning. I would hit all of the local sites like backpage, kijiji, and craigslist if I were you.

A lot of people treat Google and other search engines like they are the end all know all of everything. But honestly, in some situations they are not. Recently we had a new concrete patio poured. Craigslist was the first place I looked, then I researched the people individually on Google. I think a lot of people do that for local services still.

One last thing I would like to mention, if you do make posts on craigslist, create an image for the post. Upload the image to your website and embed the image in the post with html. The reason being is if you just upload images in their viewer, you cannot track them. Doing it this way, you can track them and find the best time to post your ads.

I hope this helps a bit.
