Welcome to the Q&A Forum

This would only work if the old site is still live, you need to place the canonical tag in the old page pointing to the new page to transfere link juice. You can only transfer link juice thought a request (eg: a link)if no links point to old pages, there is no need for the link juice

Hi As an interesting free tool have a look at Ubersuggest which pulls keyword searches from Google Suggest. KeywordEye seems to be talked about a fair bit in my circles recently, but I haven't used it before. It's a subscription tool. Market Samurai is a download and install, pay once tool that's been popular but I don't hear it talked about so much these days. I'm sure others will suggest some worth looking at. Peter

First, I wouldn't use https unless you really need that page to be secure, such as forms, shopping carts, or any page where someone inputs personal information, or where their personal information (or others') is displayed. Second, in cases where you really need to use https then yes, I would 301 redirect the http version to the https version of the page. You may also consider using rel canonical tags to help search engines figure out which version is the one you want them to use. Lastly, if you choose to go with http on some of those pages just make sure you update all of the internal links so they point to the right URL instead of relying on the redirects to do this for you.

As Frankenstein always says "Thin, duplicate content bad!" As Matt Cutts says "Comprehensive, unique content good!" You need to configure the catalog with unique titles and descriptions for each product page and make sure that each product page is information rich - great descriptions, pictures, reviews etc.  You will need to spend some time on this.  Possibly pay an intern or someone on oDesk to work in this for you.  Also, the navigation through the product pages in the catalog needs to be clear, a single path through it for bots so that they do not get in an infinite loop of search results and filters to thin search result pages.  If you have any search/ resort/filter options for search results you need to nofollow links to those pages and noindex those result pages. If you already have an online catalog and this new one is duplicating the old one, you need to consolidate the two and get as much unique helpful and easily accessible content as you can on the site.

In my opinion, I don’t think there is a problem and you should let them link to you but always make sure that they mostly target your brand name instead of a keyword because if they started to target any keyword across different website it will give Google a negative signal about the reputation of your website but having a link with a logo or brand name anchor text is fine and you can allow your manufacturers to link to you!

We have the same issue with our site HelloCoin, its pure ajax/javascript so we make a second no javascript version for every page for googlebot to crawl it, we just make it as much as possible similar to the original (user version). Just don't hide anything and show everything as it is, some functionality might not work but its not an issue, google just want to see how it looks for the user not how it works.

Google almost never indexes hashtags, since they generally point to content on the same page. Typically, Google will just strip out the hashtag when evaluating the link. However, I have seen with Wikipedia that Google will sometimes show hashtags as sitelinks. Wikipedia is the only site that I know of that they do this for. Long story short, it should be fine to leave in the hashtags and Google should just ignore them.
