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.

Moving pages to new domain
Hello, Our product pages are ranked #1 on google for our target keywords using our domain e.g. www.olddomain.com/cases/productxyz and sell about 20 products all ranked #1. We have a new company called www.newco.com/case/product1, 2, 3 etc. We use woocommerce e-commerce for both old and new sites. What is the best way to list our old co-products on our new site and move over the #1 rankings? Do we create new products (using our new nice design) in the newco.com woo commerce and then redirect old co links? do we copy and paste all that old content into the newco.com? Totally confused. Thank you!

Body of text on category pages
Hello everyone, wonder if I can pick your brains about our company's website. We are a tea company - Canton Tea Co. We have been advised that it is really important to get more text onto the category pages on our website, as otherwise the page just consists of a list of products, and therefore provides Google with a ton of headers, tiny descriptions, and not enough text to allow the page to being easily indexed, therefore hurting our Google ranking for key search terms like 'Green Tea' which should lead to the Green Tea category page. So we decided to add some text to the category page. The only place for this text to go was laid over the category header image. However, it looks pretty awful and unsophisticated having this text on top of the image - please see an example, our Green Tea category page, via this link: http://www.cantonteaco.com/loose-leaf-tea-1/type/green-tea.html So I have three questions: How significant is the text on a category page such as this to that page's Google ranking? If we moved the text to an area that was hidden until clicked on, for example the 'Filter by' section that opens up when you click on it (see via URL above), would that negate the SEO benefit? Do you have any other ideas or opinions on how to resolve this? Thank you! Louise, Canton Tea Co.

2 Menu links to same page. Is this a problem?
One of my clients wants to link to the same page from several places in the navigation menu. Does this create any crawl issues or indexing problems? It's the same page (same url) so there is no duplicate content problems. Since the page is promotional, the client wants the page accessible from different places in the nav bar. Thanks, Dino

Multi-page articles, pagination, best practice...
A couple months ago we mitigated a 12-year-old site -- about 2,000 pages -- to WordPress.
Web Design | | jmueller0823
The transition was smooth (301 redirects), we haven't lost much search juice. We have about 75 multi-page articles (posts); we're using a plugin (Organize Series) to manage the pagination. On the old site, all of the pages in the series had the same title. I've since heard this is not a good SEO practice (duplicate titles). The url's were the same too, with a 'number' (designating the page number) appended to the title text. Here's my question: 1. Is there a best practice for titles & url's of multi-page articles? Let's say we have an article named: 'This is an Article' ... What if I name the pages like this:
-- This is an Article, Page 1
-- This is an Article, Page 2
-- This is an Article, Page 3 Is that a good idea? Or, should each page have a completely different title? Does it matter?
** I think for usability, the examples above are best; they give the reader context. What about url's ? Are these a good idea? /this-is-an-article-01, /this-is-an-article-02, and so on...
Does it matter? 2. I've read that maybe multi-page articles are not such a good idea -- from usability and SEO standpoints. We tend to limit our articles to about 800 words per page. So, is it better to publish 'long' articles instead of multi-page? Does it matter? I think I'm seeing a trend on content sites toward long, one-page articles. 3. Any other gotchas we should be aware of, related to SEO/ multi-page? Long post... we've gone back-and-forth on this a couple times and need to get this settled.
Thanks much! Jim0 -
What is the best tool to view your page as Googlebot?
Our site was done with asp.net and a lot of scripting. I want to see what Google can see and what it can't. What is the best tool that duplicates Googlebot? I have found several but they seem old or inaccurate.

How to Add canonical tags on .ASPX pages?
What is the proper way (or is it possible) to add canonical tags on website pages that end in .aspx? If you add a canonical tag to the Master Page it will put that exact canonical tag on every page, which is bad. Is there a different version of the tag to put on individual pages? And one to put on the home page without the Master Page error?
