The URL you displayed as an example looks like in-page bookmarking and as far as my knowledge goes this does not make the content duplicated.

But as far as the canonicals are concern, adding a canonical URL on the website is better as it can save you from any unforeseen problems but as far as the problem you are mentioning is concern, I don’t think this will create a duplicate content within your website.

Hope this helps!

It has been a while that Google stops providing keyword DATA to webmasters so if you want to know the exact terms which drives traffic to the website and provide you conversions then forget about it Google is no more going to provide the data and by the time this %age of “not provided” is going to increase instead of decreasing.

But you can still have a bit of an idea of what keywords people might be coming from by looking in to top visited URLs and then compare it with the keywords that you are targeting on those pages. Check the ranking of the keywords in Google and you will have an idea of which keywords are working for you and which aren’t!

As per knowledge DA information updates near around every month but I don’t think there is any tool that records the history of Domain Authorities over the period of time.

At least not in my information!

Plan for today didn’t make sense to me and as far as the URL structure is concern you should have to have ea long term planning for that.

If I would be at your place I would be happy to see the URL structure which is somewhat similar to you. For example I launch a bakery business in Melbourne my ideal URL should be:

• www.mysite.com.au/melbourne/bakery/bakery224/

this way the URLs will be organized and user can easily find where his business can be available, even by looking at the URL.

As far as your idea of 302 redirections is concern I might not support that so if redirection is necessary at any point then go for 301 permanent redirections.

Hope this helps!

Title tag is great way to catches users attention and including free shipping can be an added point to cater user attention and increase the CTR volume but I believe title tag also have a much SEO value to you have to use it wisely and play it around to a place where you can incorporate branding as well as SEO keywords.

If it is not possible to add website USP in the title but you can include brand name and product titles then I would prefer to go it that way but remember in my experience Meta description also help people increase a click through rate to a greater extent so product testimonials, special features and your business USP can be used in Meta description tag to increase the CTR and conversion rate.

Hope this helps!
