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.

What’s the best tool to visualize internal link structure and relationships between pages on a single site?
I‘d like to review the internal linking structure on my site. Is there a tool that can visualize the relationships between all of the pages within my site?

How is Single Page Application (SPA) bad for SEO
Hi guys. I am quite inspired of SPA technique. It's really amazing when all your interaction with the site is going on the fly and you don't see any page reloads. I've started implementing the site with this instruction and already found nice guys to make the design. The only downside of the using SPA which I can see **is the **SEO part. That's because the URL does not really change and different pages don't have their unique URL addresses.

Actually they have, but it looks like: yoursite.com/#/products yoursite.com/#/prices yoursite.com/#/contact So all of them goes after # and being just anchors. For Google this mean all of these pages is just yoursite.com/ My question is what is really proven method to implement the URL structure in Single Page Application, so all the pages indexed by Google correctly (sorry I don't mention the other search engines because of market share). The other question, of course, is examples. It will be great to see real life site examples, better authority sites, which use SPA technique and well indexed by search engines.1 -
Dead end pages are really an issue?
Hi all, We have many pages which are help guides to our features. These pages do not have anymore outgoing links (internal / external). We haven't linked as these are already 4th level pages and specific about particular topic. So these are technically dead end pages. Do these pages really hurt us? We need to link to some other pages? Thanks

Are pages not included in navigation given less "weight"
Hi, we recently updated our website and our main navigation was dramatically slimmed down to just three pages and no drop down under those. Yet we have many more important pages, which are linked to once on one of those main three pages. However, will this hurt those other pages because they are not included in navigation (some of which were starting to get good traction in rankings)?

Internal Linking: What is the best practice for pages not included in Nav bar?
I never quite understood why internal linking was such a big deal for SEO, but now I'm having second thoughts and perhaps understanding it more. I always thought since most websites have a navigation feature--usually the menu bar located at the top and often another one in the footer--that internal navigation was usually already built in to most websites and therefore, a silly topic to make a fuss over; however, I may be the silly one after all. I am now creating pages that are not included in the navigation so.... What is the best practice for this? If I am creating say, pages for certain locations and those location pages begin to number in the hundreds, it makes my navigation bar a little too cumbersome to have all those pages in a drop down menu. So I made a Locations page and just link to all those pages from that page (and from nowhere else). But now I'm wondering if this could be a bad internal linking practice and perhaps hurt my online visibility as an SEO ranking factor. Is this a crawl problem? And if so, is there a better option that provides a good visitor experience while appeasing the search engines.

One Page Guide vs. Multiple Individual Pages
Howdy, Mozzers! I am having a battle with my inner-self regarding how to structure a resources section for our website. We're building out several pieces of content that are meant to be educational for our clients and I'm having trouble deciding how to layout the content structure. We could either layout all eight short sections on a single page, or create individual pages for each section. The goal is obviously to attract new potential clients by targeting these terms that they may be searching for in an information gathering stage. Here's my dilemma...
Web Design | | jpretz
With the single page guide, it would be nice because it will have a lot of content (and of course, keywords) to be picked up by the SERPS but I worry that it is going to be a bit crammed (because of eight sections) for the user. The individual pages would be much better organized and you can target more specific keywords, but I worry that it may get flagged for light content as some pages may have as little as a 150 word description. I have always been mindful of writing copy for searchers over spiders, but now I'm at a more technical crossroads as far as potentially getting dinged for not having robust content on each page. Here's where you come in...
What do you think is the better of the two options? I like the idea of having the multiple pages because of the ability to hone-in on a keyword and the clean, organized feel, but I worry about the lack of content (and possibly losing out on long-tail opportunities). I'd love to hear your thoughts. Please and thank you. Ready annnnnnnnnnnnd GO!0 -
Indexing Dynamic Pages
Hi, I am having an issues among others, regarding indexing dynamic pages. Our website, www.me-by-melia, was just put live and I am concerned the bottom naviagtion pages (http://www.me-by-melia.com/#store, http://www.me-by-melia.com/#facebook, etc) will not be indexed and create duplicate pages. Also, when you open these pages in a new tab, it takes you to homepage. The website was created in HTML5. Please advise.

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?
