Large robots.txt file
-
We're looking at potentially creating a robots.txt with 1450 lines in it. This will remove 100k+ pages from the crawl that are all old pages (I know, the ideal would be to delete/noindex but not viable unfortunately)
Now the issue i'm thinking is that a large robots.txt will either stop the robots.txt from being followed or will slow our crawl rate down.
Does anybody have any experience with a robots.txt of that size?

Answered my own questions:
https://developers.google.com/webmasters/control-crawl-index/docs/robots_txt?csw=1#file-format
"A maximum file size may be enforced per crawler. Content which is after the maximum file size may be ignored. Google currently enforces a size limit of 500kb."

Large Competitor closed, how to capitalize in search. Any ideas?
Hey Mozzers, One of our biggest competitors closed down on January 1st, 2020 in several US cities. They did stay open in some areas just FYI. The competitor's website is www.execucar.com. This is a very large company that has a presence in almost all US major airports. It's a private car service just like Uber but for wealthy individuals. For example. when you search " lax car service" they are #3 on Google or "car service to lax" they're #2 still. What can we do to get more of their traffic and actual business? Has anyone done something like this before or knows quick and easy tactics to get their clients? We have a local landing page: https://dcacar.com/lax-car-service that ranks 9 through 11 for those same keywords. Thanks for your thoughts and time. Davit

Should I use noindex or robots to remove pages from the Google index?
I have a Magento site and just realized we have about 800 review pages indexed. The /review directory is disallowed in robots.txt but the pages are still indexed. From my understanding robots means it will not crawl the pages BUT if the pages are still indexed if they are linked from somewhere else. I can add the noindex tag to the review pages but they wont be crawled. https://www.seroundtable.com/google-do-not-use-noindex-in-robots-txt-20873.html Should I remove the robots.txt and add the noindex? Or just add the noindex to what I already have?

Meta Robot Tag:Index, Follow, Noodp, Noydir
When should "Noodp" and "Noydir" meta robot tag be used? I have hundreds or URLs for real estate listings on my site that simply use "Index", Follow" without using Noodp and Noydir. Should the listing pages use these Noodp and Noydr also? All major landing pages use Index, Follow, Noodp, Noydir. Is this the best setting in terms of ranking and SEO. Thanks, Alan

Should I use meta noindex and robots.txt disallow?
Hi, we have an alternate "list view" version of every one of our search results pages The list view has its own URL, indicated by a URL parameter I'm concerned about wasting our crawl budget on all these list view pages, which effectively doubles the amount of pages that need crawling When they were first launched, I had the noindex meta tag be placed on all list view pages, but I'm concerned that they are still being crawled Should I therefore go ahead and also apply a robots.txt disallow on that parameter to ensure that no crawling occurs? Or, will Googlebot/Bingbot also stop crawling that page over time? I assume that noindex still means "crawl"... Thanks 🙂

Could you use a robots.txt file to disalow a duplicate content page from being crawled?
A website has duplicate content pages to make it easier for users to find the information from a couple spots in the site navigation. Site owner would like to keep it this way without hurting SEO. I've thought of using the robots.txt file to disallow search engines from crawling one of the pages. Would you think this is a workable/acceptable solution?

All page files in root? Or to use directories?
We have thousands of pages on our website; news articles, forum topics, download pages... etc - and at present they all reside in the root of the domain /. For example: /aosta-valley-i6816.html

/flight-sim-concorde-d1101.html
/what-is-best-addon-t3360.html We are considering moving over to a new URL system where we use directories. For example, the above URLs would be the following: /images/aosta-valley-i6816.html
/downloads/flight-sim-concorde-d1101.html
/forums/what-is-best-addon-t3360.html Would we have any benefit in using directories for SEO purposes? Would our current system perhaps mean too many files in the root / flagging as spammy? Would it be even better to use the following system which removes file endings completely and suggests each page is a directory: /images/aosta-valley/6816/
/downloads/flight-sim-concorde/1101/
/forums/what-is-best-addon/3360/ If so, what would be better: /images/aosta-valley/6816/ or /images/6816/aosta-valley/ Just looking for some clarity to our problem! Thank you for your help guys!0 -
Blocking Dynamic URLs with Robots.txt
Background: My e-commerce site uses a lot of layered navigation and sorting links. While this is great for users, it ends up in a lot of URL variations of the same page being crawled by Google. For example, a standard category page: www.mysite.com/widgets.html ...which uses a "Price" layered navigation sidebar to filter products based on price also produces the following URLs which link to the same page: http://www.mysite.com/widgets.html?price=1%2C250 http://www.mysite.com/widgets.html?price=2%2C250 http://www.mysite.com/widgets.html?price=3%2C250 As there are literally thousands of these URL variations being indexed, so I'd like to use Robots.txt to disallow these variations. Question: Is this a wise thing to do? Or does Google take into account layered navigation links by default, and I don't need to worry. To implement, I was going to do the following in Robots.txt: User-agent: * Disallow: /*? Disallow: /*= ....which would prevent any dynamic URL with a '?" or '=' from being indexed. Is there a better way to do this, or is this a good solution? Thank you!
