Welcome to the Q&A Forum

It would be generally recommended you also include a <noscript><img src=""></noscript> section for crawlers and other visitors without JavaScript turned on. I would have at least hoped your solution would use the element rather than a completely non-standard approach to display images. Not sure what library, provider or script you are using but maybe check out a responsive image service like Pixtulate who would actually allow you to use a standard img tag and still accomplish what you are looking to do.

Cross-domain canonical is the most viable option here. As Mike and Chris said, it is possible for Google to ignore the tag in some cases, but it's a fairly strong suggestion. There are two main reasons I'd recommend it: (1) Syndicated content is the entire reason Google allowed the use of rel=canonical across domains. SEOs I know at large publishers have used it very effectively. While your situation may not be entirely the same, it sounds similar to a syndicated content scenario. (2) It's really your only viable option. While a 301-redirect is almost always honored by Google, as Chris suggested, it's also very different. A 301 will take the visitors on the partner site page directly to your page, and that's not your intent. Rel=canonical will leave visitors on the partner page, but tell search engines to credit that page to the source. Google experimented with a content syndication tag, but that tag's been deprecated, so in most cases rel=canonical is the best choice we have left.

Hi, if you use Followerwonk that will show you all your followers in one place. However, there isn't a differentiation with Twitter (unless it is something they have added recently) between a personal or a business account. So you can only check each of the profiles and try and work out which ones are personal and which are for business. Some will be obvious, some less so. I know it's not the answer you were looking for specifically, but I hope it helps, Peter

Hello ShearingsGroup, You'll find tools that do that, and many other things, in this 100 Free SEO Tools post here on Moz.com. To answer your question though, I like SEM Rush for this purpose. You can also try SpyFu and several other tools. And here's a recent post on Net Magazine that should be helpful as well.

Hi there! Thanks for reaching out to us! I am sorry if Roger is somehow not following your robots.txt directives.  To ensure that Roger doesn't crawl your site you can put the following directive above your general directives in your robots.txt: User-agent: rogerbot Dissallow: / Once this is in place you should find our crawler to be a lot more obedient towards your site. Hope this helps, please let us know if you have any more questions about our crawler. Best, Peter Moz Help Team.

Thanks for your suggestions. I've already got canonical tags on every page, but they're not all being adhered to and lots of URLs with query strings are still getting organic traffic. Passing referrer info behind scenes isn't an option with Coremetrics I don't think. Is it? Interested to know more about number 1 though. How would you do that in WMT other than blocking with robots.txt? Thanks

Unfortunately, what Google can do and what they actually do can really vary. If you're mixing signals and doubling up the canonicals, the odds that they'll get it right are pretty low, in my experience. I think it's worth the fix, if these are traffic-generating pages.
