Robots.txt, does it need preceding directory structure?
-
Do you need the entire preceding path in robots.txt for it to match?
e.g:
I know if i add Disallow: /fish to robots.txt it will block
/fish
/fish.html
/fish/salmon.html
/fishheads
/fishheads/yummy.html
/fish.php?id=anythingBut would it block?:
en/fish
en/fish.html
en/fish/salmon.html
en/fishheads
en/fishheads/yummy.html
**en/fish.php?id=anything(taken from Robots.txt Specifications)** I'm hoping it actually wont match, that way writing this particular robots.txt will be much easier!
As basically I'm wanting to block many URL that have BTS- in such as:
http://www.example.com/BTS-something
http://www.example.com/BTS-somethingelse
http://www.example.com/BTS-thingybobBut have other pages that I do not want blocked, in subfolders that also have BTS- in, such as:
http://www.example.com/somesubfolder/BTS-thingy
http://www.example.com/anothersubfolder/BTS-otherthingyThanks for listening
-
Yes this is what I thought, but wanted some second opinions.
Although I wouldn't actually need a wild card after BTS, as just leaving it open is the same as using a wildcard:
/fish*.......... Equivalent to "/fish" -- the trailing wildcard is ignored. https://developers.google.com/webmasters/control-crawl-index/docs/robots_txt Thanks for the link, I'll take a look
-
You're right in with the **Disallow: /fish **in the robots file blocking all those initial links, but if you wanted to block everything inside the /en/ folder, you would need to do disallow: /en/fish
You could use a wildcard in the robots.txt file to do something along the lines of Disallow: /BTS-*
This _'should' _work, but it's always worth checking using a tool to make sure it's all implemented correctly. Distilled did a post a while back about a JS tool which allows you to test if robots.txt files work correctly which can be found here - http://www.distilled.net/blog/seo/js-bookmarklet-for-checking-if-a-page-is-blocked-by-robots-txt/
In addition to this, you could also use the 'blocked URLs' tool in GWT to see if the pages are successfully blocked once you've implemented the code.
Hope this helps!

Robots.txt blocked internal resources Wordpress
Hi all, We've recently migrated a Wordpress website from staging to live, but the robots.txt was deleted. I've created the following new one: User-agent: *
Intermediate & Advanced SEO | | Mat_C
Allow: /
Disallow: /wp-admin/
Disallow: /wp-includes/
Disallow: /wp-content/plugins/
Disallow: /wp-content/cache/
Disallow: /wp-content/themes/
Allow: /wp-admin/admin-ajax.php However, in the site audit on SemRush, I now get the mention that a lot of pages have issues with blocked internal resources in robots.txt file. These blocked internal resources are all cached and minified css elements: links, images and scripts. Does this mean that Google won't crawl some parts of these pages with blocked resources correctly and thus won't be able to follow these links and index the images? In other words, is this any cause for concern regarding SEO? Of course I can change the robots.txt again, but will urls like https://example.com/wp-content/cache/minify/df983.js end up in the index? Thanks for your thoughts!2 -
How to rank if you are an aggregator or a directory of resource?
Most of the SEO suggestions (great quality content, long form content, engagement rate/time on the page, authority inbound links ) apply to content oriented site. But what should you do if you are an aggregator or a resource directory? You aim is to send the user faster to other site they are looking for or provide ranking about the resources. In fact at a very basic level you are competing for search engine traffic because they are doing same things. You may have done a hand crafted, human created resource that is better than what algorithms are showing. And your site likely to have lot more outgoing links than content. You know you are better (or getting better) since repeat visitors keep coming back. So in these days of Search engines, what a resource directory or aggregator site do to rank? Because even directories need first time visitors till they start coming back again.

Does it hurt your SEO to have an inaccessible directory in your site structure?
Due to CMS constraints, there may be some nodes in our site tree that are inaccessible and will automatically redirect to their parent folder. Here's an example: www.site.com/folder1/folder2/content, /folder2 redirects to /folder1. This would only be for the single URL itself, not the subpages (i.e. /folder1/folder2/content and anything below that would be accessible). Is there any real risk in this approach from a technical SEO perspective? I'm thinking this is likely a non-issue but I'm hoping someone with more experience can confirm. Another potential option is to have /folder2 accessible (it would be 100% identical to /folder1, long story) and use a canonical tag to point back to /folder1. I'm still waiting to hear if this is possible. Thanks in advance!

Disallow URLs ENDING with certain values in robots.txt?
Is there any way to disallow URLs ending in a certain value? For example, if I have the following product page URL: http://website.com/category/product1, and I want to disallow /category/product1/review, /category/product2/review, etc. without disallowing the product pages themselves, is there any shortcut to do this, or must I disallow each gallery page individually?

Structured Data + Meta Descriptions
Hey All, Was just looking through some google pages on best practices for meta descriptions and came across this little tidbit. "Include clearly tagged facts in the description. The meta description doesn't just have to be in sentence format; it's also a great place to include structured data about the page. For example, news or blog postings can list the author, date of publication, or byline information. This can give potential visitors very relevant information that might not be displayed in the snippet otherwise. Similarly, product pages might have the key bits of information—price, age, manufacturer—scattered throughout a page. A good meta description can bring all this data together. For example, the following meta description provides detailed information about a book. " This is the first time I have seen suggested use of structured data in meta descriptions. Does this totally replace a regular meta description or will it work in conjunction with the regular meta description? If I provide both structured data and text, will the SERP display text and the structured data the way it was previously displayed? Or will the 150 -160 character limit take precedence and just cut off all info after that?

"noindex, follow" or "robots.txt" for thin content pages
Does anyone have any testing evidence what is better to use for pages with thin content, yet important pages to keep on a website? I am referring to content shared across multiple websites (such as e-commerce, real estate etc). Imagine a website with 300 high quality pages indexed and 5,000 thin product type pages, which are pages that would not generate relevant search traffic. Question goes: Does the interlinking value achieved by "noindex, follow" outweigh the negative of Google having to crawl all those "noindex" pages? With robots.txt one has Google's crawling focus on just the important pages that are indexed and that may give ranking a boost. Any experiments with insight to this would be great. I do get the story about "make the pages unique", "get customer reviews and comments" etc....but the above question is the important question here.

Avoiding Duplicate Content with Used Car Listings Database: Robots.txt vs Noindex vs Hash URLs (Help!)
Hi Guys, We have developed a plugin that allows us to display used vehicle listings from a centralized, third-party database. The functionality works similar to autotrader.com or cargurus.com, and there are two primary components: 1. Vehicle Listings Pages: this is the page where the user can use various filters to narrow the vehicle listings to find the vehicle they want.
Intermediate & Advanced SEO | | browndoginteractive
2. Vehicle Details Pages: this is the page where the user actually views the details about said vehicle. It is served up via Ajax, in a dialog box on the Vehicle Listings Pages. Example functionality: http://screencast.com/t/kArKm4tBo The Vehicle Listings pages (#1), we do want indexed and to rank. These pages have additional content besides the vehicle listings themselves, and those results are randomized or sliced/diced in different and unique ways. They're also updated twice per day. We do not want to index #2, the Vehicle Details pages, as these pages appear and disappear all of the time, based on dealer inventory, and don't have much value in the SERPs. Additionally, other sites such as autotrader.com, Yahoo Autos, and others draw from this same database, so we're worried about duplicate content. For instance, entering a snippet of dealer-provided content for one specific listing that Google indexed yielded 8,200+ results: Example Google query. We did not originally think that Google would even be able to index these pages, as they are served up via Ajax. However, it seems we were wrong, as Google has already begun indexing them. Not only is duplicate content an issue, but these pages are not meant for visitors to navigate to directly! If a user were to navigate to the url directly, from the SERPs, they would see a page that isn't styled right. Now we have to determine the right solution to keep these pages out of the index: robots.txt, noindex meta tags, or hash (#) internal links. Robots.txt Advantages: Super easy to implement Conserves crawl budget for large sites Ensures crawler doesn't get stuck. After all, if our website only has 500 pages that we really want indexed and ranked, and vehicle details pages constitute another 1,000,000,000 pages, it doesn't seem to make sense to make Googlebot crawl all of those pages. Robots.txt Disadvantages: Doesn't prevent pages from being indexed, as we've seen, probably because there are internal links to these pages. We could nofollow these internal links, thereby minimizing indexation, but this would lead to each 10-25 noindex internal links on each Vehicle Listings page (will Google think we're pagerank sculpting?) Noindex Advantages: Does prevent vehicle details pages from being indexed Allows ALL pages to be crawled (advantage?) Noindex Disadvantages: Difficult to implement (vehicle details pages are served using ajax, so they have no tag. Solution would have to involve X-Robots-Tag HTTP header and Apache, sending a noindex tag based on querystring variables, similar to this stackoverflow solution. This means the plugin functionality is no longer self-contained, and some hosts may not allow these types of Apache rewrites (as I understand it) Forces (or rather allows) Googlebot to crawl hundreds of thousands of noindex pages. I say "force" because of the crawl budget required. Crawler could get stuck/lost in so many pages, and my not like crawling a site with 1,000,000,000 pages, 99.9% of which are noindexed. Cannot be used in conjunction with robots.txt. After all, crawler never reads noindex meta tag if blocked by robots.txt Hash (#) URL Advantages: By using for links on Vehicle Listing pages to Vehicle Details pages (such as "Contact Seller" buttons), coupled with Javascript, crawler won't be able to follow/crawl these links. Best of both worlds: crawl budget isn't overtaxed by thousands of noindex pages, and internal links used to index robots.txt-disallowed pages are gone. Accomplishes same thing as "nofollowing" these links, but without looking like pagerank sculpting (?) Does not require complex Apache stuff Hash (#) URL Disdvantages: Is Google suspicious of sites with (some) internal links structured like this, since they can't crawl/follow them? Initially, we implemented robots.txt--the "sledgehammer solution." We figured that we'd have a happier crawler this way, as it wouldn't have to crawl zillions of partially duplicate vehicle details pages, and we wanted it to be like these pages didn't even exist. However, Google seems to be indexing many of these pages anyway, probably based on internal links pointing to them. We could nofollow the links pointing to these pages, but we don't want it to look like we're pagerank sculpting or something like that. If we implement noindex on these pages (and doing so is a difficult task itself), then we will be certain these pages aren't indexed. However, to do so we will have to remove the robots.txt disallowal, in order to let the crawler read the noindex tag on these pages. Intuitively, it doesn't make sense to me to make googlebot crawl zillions of vehicle details pages, all of which are noindexed, and it could easily get stuck/lost/etc. It seems like a waste of resources, and in some shadowy way bad for SEO. My developers are pushing for the third solution: using the hash URLs. This works on all hosts and keeps all functionality in the plugin self-contained (unlike noindex), and conserves crawl budget while keeping vehicle details page out of the index (unlike robots.txt). But I don't want Google to slap us 6-12 months from now because it doesn't like links like these (). Any thoughts or advice you guys have would be hugely appreciated, as I've been going in circles, circles, circles on this for a couple of days now. Also, I can provide a test site URL if you'd like to see the functionality in action.0
