Reason for robots.txt file blocking products on category pages?
-
Hi
I have a website with thosands of products. On the category pages, all the products are linked to with the code “?cgid” in the URL. But “?cgid” is also blocked in the robots.txt file for some reason. So I'm thinking it's stopping all my products getting crawled by Google.
Am I right here? Is there any reason why a website would want to limit so many URL's? I'm only here a week and the sites getting great traffic, so don't want to go breaking it!!!
Thanks

Thanks again AL123al!
I would be concerned about my internal linking because of this problem. I've always wanted to keep important pages within 3 clicks of the Homepage. My worry here is that while these products can get clicked by a user within 3 clicks of the Homepage, they're blocked to Googlebot.
So the product URLS are only getting crawled in the sitemap, which would be hugely ineffcient? So I think I have to decide whether opening up these pages will improve my linking structure for Google to crawl the product pages, but is that important than increasing the amount of pages it's able to crawl and wasting crawl budget?

Hello,
The canonical product URLS will be getting crawled just fine as they are not blocked in the robots.txt. Without understanding your problem completely, I think the guys before you were trying to stop all the duplicate URLS with parameters being crawled and just leaving Google to crawl the canonicals - which is what you want.
If you remove the parameter from robots.txt then Google will crawl everything including the parameter URLS. This will waste crawl budget. So better that Google is only crawling the canonicals.
Regarding the sitemap, being present on the sitemap will help Googlebot decide what to prioritise crawling but won't stop it finding other URLS if there is good internal linking.

Thanks AL123al! The base URL's (www.example.com/product-category/ladies-shoes) do seem to be getting crawled here & there, and some are ranking which is great. But I think the only place they can get crawled is the sitemap, which has has over 28,000 URLs on one page (another thing I need to fix)!
So if Googlebot gets to the parameter URL through category pages (www.example.com/product-category/ladies-shoes?cgid...) and sees it's blocked, I'm guessing it can't see it's important to us (from the website hierarchy) or the canonical tag, so I'm presuming it's seriously damaging or power in getting products ranked
In Screaming Frog, 112,000 get crawled and 68% are blocked by robots. 17,000 are URL's which contain "?cgid", which I don't think is too big for Googlebot to crawl, the websites has a pretty good authority so I think we have a pretty deep crawl.
So I suppose what really want to know is will removing "?cgid" from the robots file really damage the site? I my opinion, I think it'll really help

This looks like the products are being appended by a parameter ?cgid - there may be other stuff attached to the end of each URL like this below:
e.g. www.example.com/product-category/ladies-shoes?cgid-product=19&controller=product etc
but canonical URL is www.example.com/product-category/ladies-shoes
These products may have had a canonical to the base URL which means that there won't be any problem with duplicates being indexed. So all well and good.
Except.....Google has to crawl each of these parameter URLs to find the canonical. In a huge website this means that crawl budget is being consumed by unnecessary crawling of these parameterised URLs.
You can tell Google not to crawl the parameter URLs in search console (at least in the old version you can). But you can also stop Google crawling these URLS unnecessarily by blocking them in robots txt if you are sure that the parameters are not changing how the page is looking in search.
So long story short is that is why you may see that the URLS with parameters are being blocked in robots.txt. The canonical version URLS will be getting crawled just fine since they don't have any parameters and hence not being blocked.
Hope that makes sense?

Yes, it's in the robot.txt, that's the problem. Someone had to physically put it in there, but I've no idea why they would.

Did you check your robot txt file? Or check if any plugin creating this problem.

JSON-LD product page markup for multiple currencies?
I haven't found a working example of a single product page with one "Offer" in multiple "priceCurrency" and "price" We have product pages with a single product URL which will offer different prices in different currencies based on the user's IP. Some of the language of the page will be translated based on the IP (this will have href lang tag) but the URL will not change. (We're aware TLD is considered best practice, however, this is not an option at this time.) Is the best option to update the markup based on what the corresponding "country"? I'm uncertain how this may be handled by crawlers. Eg, For the product page https://www.example.com/product1 displaying USD "offers": {

WordPress Category page title h1 or h2
Hi friends, I know this is a minor technical change, but we are in an extremely competitive market and I don't want to have any points against us. On our WordPress Category pages i.e. http://www.domain.com/category/�tegory-title%/ I looked at the code behind the the Title of the category page, which is "Browsing: %Category Title%" The code is an h2. I look at the posts in the category archive below, and those are also h2's. The theme preview is here and you can click on Entertainment - Reviews to see exactly what I'm referring to - http://themeforest.net/item/smartmag-responsive-retina-wordpress-magazine/full_screen_preview/6652608 I changed the code for the "Browsing: %Category Title%" to h1, which I believe is more consistent and standard formatting. 1. Is this a correct technical on-page optimization? 2. Would it be beneficial to remove "Browsing"?

Help with Schema.org on Ecommerce Products
I’m looking for ways of using schema.org with products that have pricing options. There appear to be two main problems 1) Whilst colour, width, height and depth are all catered for, size appears to be missing – how can we mark up products that are available in sizes that aren’t necessarily covered by width/height/depth (e.g. shoe size). Also, what if the product is available in different finishes – technically, these could not properly be described as colours so how could we mark them up? 2) There doesn’t seem to be any particularly good way of marking up pricing options that are displayed on the same product detail page. For e.g. if a pricing option table is used like this: | ID | Colour | Price 001-red | Red | £3.99 001-green | Green | £4.49 001-blue | Blue | £4.99 | I can mark up each row as an offer, and give each offer a price and sku or mpn, but then I can’t use itemprop=”color” to describe exactly what the option is. Would I just use itemprop=”name” in this case and abandon color altogether (even though it’s technically supposed to be describing the colour of the product and not the name of the offer)? I suppose another way I could approach it would be to mark up each row as an individual product, and assign each one an offer with the details as described above but then the containing page would effectively look like a separate product – which it isn’t. Any help or advice on this would be very much appreciated

What seo benefit does setting up a photo gallery where each photo is a separate web page?
what seo benefit does setting up a photo gallery where each photo is a separate web page? My old SEO guy set up my photo gallery like that claiming that because each photo was a separate page, it added a big seo benefit and i never understood what he was talking about. Maybe alt text on the photo with key phrases in it pointing to my other pages to give my site a theme for google? I'm not really sure. He has since moved away and i am considering redoing the photo gallery to multiple images on one page to be more user friendly to my users. This photo gallery is 3 years old and the photos might have some page rank to them helping my site so i don't want to remove this gallery if there really is a benefit to it and it will hurt my site. I once removed four static page rank 3 pages from my site that weren't used for my site anymore and my rankings dropped 5 positions. Thoughts anyone? Thanks! Ron

Is it better to redirect a url or set up a landing page for a new site?
Hi, One of our clients has got a new website but is still getting quite a lot of traffic to her old site which has a page authority of 30 on the home page and has about 20 external backlinks. It's on a different hosting package so a different C block but I was wondering if anyone could advise if it would be better to simply redirect this page to the new site or set up a landing page on this domain simply saying "Site has moved, you can now find us here..." sort of idea. Any advice would be much appreciated Thanks

Does it do harm if you add a rel="canonical" tag on a page that doesn't need it?
If a page is clearly unique and there is obviously no canonical tag needed, does it hurt anything if one has been added?

IP block in Google
Our office has a number of people performing analysis and research on keyword positions, volume, competition etc. We have 1 external static IP address. We installed the static IP so we can filter out our visits in Google Analytics. However by 10 AM we get impssible CAPTCHA's or even get blocked in Google. Do you have any experience with such an issue? Any solutions you can recommend? Any help would be appreciated! SXI5A.png
