Welcome to the Q&A Forum

Choosing a host would entirely depend on on your requirement. I seriously doubt having your site hosted with them would cause it not to be  crawled. ( unless of course the server you have with them have explicitly prevented bots crawling the pages in there , which would make no sense for them to do )

Short answer Yes.( as long as you have rel Canonical them back to the original page ). Google will drop the other pages over time

Things you can do here :

• Make sure your sitemap is not listing these extra urls

Thing I recommend you DONT do

• noIndex the dynamic pages - adding a noindex could tell google not to index those pages, but some one could link back to that page with P_SOURCE=WBFQ and the main page gets no benefit from that
• ask for manual removal ( because google does not like it when we ask them To get the right "version" of your site indexedhttp://support.google.com/webmasters/bin/answer.py?hl=en&answer=1269119 )

Hope that answers you questions

Hi Nola504

301 redirect is certainly NOT your solution .. if you 301 redirect www.url.com/index.php?P_SOURCE=WBFQ to your homepage , that is the page visitors will be redirected to ( the ?P_SOURCE=WBFQ will be stripped off , I dont think that is what you want )

Rel canonical will tell Google , thay are all the same page with the same content and it will only show the main url that you nominate as the  Canonical url ( in most cases , I have read about some study which claims at times google might decide for itself which is the better page )

Its a bit technical but you can go through this https://developers.google.com/webmasters/ajax-crawling/ to make sure the dynamic page that you generate is actually indexable by Google.

That said 5000+ products infinite scroll is a bit scary and I would look at using rel=next and rel=prev for the pagination ( http://googlewebmastercentral.blogspot.com.au/2011/09/pagination-with-relnext-and-relprev.html )

I am not too sure what you mean by " internally linked to from the browsing results pages in the category structure: e.g. Blue Widgets, Widgets Under $250, etc. "

If you are referring to ability for users to sort through those products by picking one of the options like Blue Widgets, Widgets Under $250, etc. I would suggest rel canonical those pages to the base page . This should get you started http://support.google.com/webmasters/bin/answer.py?hl=en&answer=139394

I have no data to draw the conclusion from but I get how more users might click on PPC especially the ones on top of the SERPs . Would be interesting to see if anyone has some stats on these.

Just a FYI , Big G recommends responsive web design when it comes to mobile pages

http://googlewebmastercentral.blogspot.com.au/2012/06/recommendations-for-building-smartphone.html

so if you have an in house developer you might want to go down that road.

My Theory On this ( I have no tests to prove this )

If you upload a verified site map thats is essentially telling Google these are the important pages on my site. would you want to risk the importance of the other pages by telling Google you consider only the few important categories as the important ones . They wont drop the other pages completely but MIGHT see them as less important .

I really don't see Google penalizing a site for incomplete sitemaps.

If you have a really large site you might also want to look in to multiple sitemaps : http://googlewebmastercentral.blogspot.com.au/2006/10/multiple-sitemaps-in-same-directory.html

You might also want to look in to the best situations to use rel canonical vs a 301 redirect .

Its like comparing Apples to Mangoes really . If you are having client who seems to be confused  .. you should educate them about what each of them offers.

With organic you need to invest time and effort and the results will take time .. With PPC  you get value based on the Money you put it ( that is not to say there is no time / effort put in to it ) and can be used for quick wins.

I am answering this assuming you own zenucchi.it

http://poltronafraubrescia.zenucchi.it  and www.zenucchi.it/ITA/poltrona-frau-brescia.html are on the same domain why try to target 2 different pages for the same keyword ?

UPDATE : ( missed the 301 redirect part in the title ..doh )

Once you do a redirect , its best you build link to the new page.

I would not worry about multiple H1 as a major issue .( as long you are not over doing it )

If you can show the image on the page then do that . I think it would be better for users too instead of an unwanted click to open up another page which takes them away from your products page.

Perhaps you can add one as a subcategory . If you cater for shirts from many brands you could have

Shirts >> Gucci

If you offer various Gucci Products You could have

Gucci >> Shirts

Its also perfectly fine to have both of them as main categories as long as they don't both offer the exact same content .. eg: you only show 10 items on a page and you have 10 shirts all of them Gucci then it could be seen as a duplicate page

I am not really sure what you want to get done. If you want to display the "certificate of authenticity" as an image you can JPG.

No Worries .. I was referring to the avatar pic you use

Someone is a happy Panda ^_^

If you have structured you site well and don't go overboard with Categories / Tags then by all means leave them to be indexed BUT make sure to add a Title and Description for each of those Categories and Tags.

With Media I find it useful to index them .. made sure you add a alt tag for you images and add relevant titles for them.

Author Archives : If it's a single person blog then I would suggest to avoid using them and add a noindex to author archives BUT since your wife contributes to the blog my advice is to leave them as indexable ( make sure you add a Title and Description for this as well)

Adding a NOFOLLOW will tell the bot not to follow any links from that page. I usually don't add that.

Other than the obvious reply of your client editing the listing to show that . It could have something to do with Google's effort to craft titles depending on what they think is the best fit ( it could be expanding in to Local too ? MY Speculation )

I dont see why you need to rel canonical the page to itself .

I believe you can get in touch with the dev team here to get them to fix this issue .

Hi Kevin

so its not just me then .. I will update the post with any info I get

Thanks mate ... its been a couple of weeks now.

Is there a certain limit that you have to hit before the profile picture becomes visible ? I can see it on my blog profile but in Q&A its the default image
