Setting A Custom User Agent in Screaming Frog
-
Hi all,
Probably a dumb question, but I wanted to make sure I get this right.
How do we set a custom user agent in Screaming Frog? I know its in the configuration settings, but what do I have to do to create a custom user agent specifically for a website?
Thanks much!

Setting a custom user agent determines things like HTTP/2 so there can be a big difference if you change it to something that might not take advantage of something like HTTP/2
Apparently, it is coming to Pingdom very soon just like it is to Googlebot
http://royal.pingdom.com/2015/06/11/http2-new-protocol/
This Is an excellent example of a user agent's ability to modify the way your site is crawled as well as how efficient it is.

It is important to note that we didn’t use Pingdom in any of our tests because they use Chrome 39, which doesn’t support the new HTTP/2 protocol. HTTP/2 in Chrome isn’t supported until Chrome 43. You can tell this by looking at the
User-Agentin the request headers of your test results.
Pingdom user-agent
Note: WebPageTest uses Chrome 47 which does support HTTP/2.
Hope that clears things up,

Hi Malika,
Think about screaming frog and what it has to detect in order to do that correctly it needs the correct user agent syntax for it will not be able to make a crawl that would satisfy people.
Using a proper syntax for a user agent is essential and I have tried to be non-technical in this explanation I hope it works.
the reason screaming frog needs the user agent because the user-agent was added to HTTP to help web application developers deliver a better user experience. By respecting the syntax and semantics of the header, we make it easier and faster for header parsers to extract useful information from the headers that we can then act on.
Browser vendors are motivated to make web sites work no matter what specification violations are made. When the developers building web applications don’t care about following the rules, the browser vendors work to accommodate that. It is only by us application developers developing a healthy respect

It is only by us application developers developing a healthy respect for the standards of the web, that the browser vendors will be able to start tightening up their codebase knowing that they don’t need to account for non-conformances.
For client libraries that do not enforce the syntax rules, you run the risk of using invalid characters that many server side frameworks will not detect. It is possible that only certain users, in particular, environments would identify the syntax violation. This can lead to difficult to track down bugs.
I hope this is a good explanation I've tried to keep it very to the point.
Respectfully,
Thomas

Hi Thomas,
would you have a simpler tutorial for me to understand? I am struggling a bit.
Thanks heaps in advance
-
I think I want something that is dumbed down to my level for me to understand. The above tutorials are great but not being a full time coder, I get lost while reading those.

Hi Matt,
I havent had a luck with this one yet.
-
Hi Malika! How'd it go? Did everything work out?
-
happy I could be of help let me know if there's any issue and I will try to be of help with it. All the best
-
Hi Thomas,
That's a lot of useful information there. I will have a go on it and let you know how it went.
Thanks heaps!

please let me know if I did not answer the question or you have any other questions

this gives you a very clear breakdown of user agents and their set of syntax rules. The following is valid example of user-agent that is full of special characters,
read this please http://www.bizcoder.com/the-much-maligned-user-agent-header
user-agent: foo&bar-product!/1.0a$*+ (a;comment,full=of/delimitersreferences but you want to pay attention to the first URL

if you formatted it correctly see below
User-Agent = product *( RWS ( product / comment ) )and it was received by your headers yes you could fill in the blanks and test it.

No, you Cannot just put anything in there. The site has to recognize it and ask why you are doing this?
I have listed how to build and already built in addition to what your browser will create by using useragentstring.com
Must be formatted correctly and have it work with a header it is not as easy as it sometimes seems but not that hard either.
You can make & use this to make your own from your Mac or PC

Hi Thomas,
Thanks for responding, much appreciated!
Does that mean, if I type in something like -
HTTP request user agent -
Crawler access V2
&
Robots user agent
Crawler access V2
This will work too?
-
To crawl using a different user agent, select ‘User Agent’ in the ‘Configuration’ menu, then select a search bot from the drop-down or type in your desired user agent strings.

Kind of duplicate categories and custom taxonomy. Necessary, but bad for SEO?
Hello Everyone! I'm new here! My husband and I are working on creating a website: https://sacwellness.com .The site is an online therapist directory for the the Sacramento California area. Our problem is this: In wordpress our category system is being used for blog posts. Our theme is using a custom taxonomy system to categorize different therapist specialties, therapeutic approaches, etc. We've found ourselves in a position where our custom taxonomy and categories are near duplicates. for example we have the blog categories: ADHD counseling, Anxiety therapy, and Career counseling our corresponding custom taxonomy/therapist categories are: ADHD, Anxiety, and....(oops) career counseling. My understanding is that google doesn't see a difference between identically named categories and custom taxonomies and will so choose one to rank and disregard the other, effectively leaving you competing against yourself. is this true in a case like this? Can google maybe understand the difference because of the custom taxonomy and/or URL paths? if this is a problem is it ok to have near duplicates....like ADHD vs. ADHD counseling. This has been our solution so far....but now we're questioning it....derp x_x. I thought about tagging the categories with no index, but I think the archive pages would be useful for people. Essentially we have 2 sets of archives for each keyword. One is for blog posts, and one is for therapists who work with that particular issue along with the 6 most recent blog posts in that category.....because we are putting the 6 most recent blog posts at the bottom of the therapist pages I feel like it wouldn't be as terrible of a loss if we had to noindex the category pages. ....what do you think? Thank you!

Set Placeholder Page ASAP or Wait For Full Website?
It can take some time for a new business website to get picked up by all the search engines and indexed. Let's assume it's going to take a month to build your new full-fledged business website. Would it be advantageous in the mean time to immediately launch the domain with an introductory website using a template site so you might have just two pages, a home page with logo, title, brief description of pages, a couple images, etc and a contact page. Would this help give the site a "jump start" on being indexed? Or could that do more harm than good by putting up something "quick & dirty" versus the complete website with much more content, that has been SEO optimized?

Screaming Frog returning both HTTP and HTTPS results...
Hi, About 10 months I switched from HTTP to HTTPS. I then switched back (long story). I noticed that Screaming Frog is picking up the HTTP and HTTPS version of the site. Maybe this doesn't matter, but I'd like to know why SF is doing that. The URL is: www.aerlawgroup.com Any feedback, including how to remove the HTTPS version, is greatly appreciated. Thanks.

What happens to a domain in SERPs when it's set to redirect to another?
We have just acquired a competing website and are wondering whether to leave it running as is for now, or set the domain to redirect to our own site. If we set up this redirect, what would happen to the old site in Google SERPs? Would the site drop off from results? If so, would we capture this new search traffic or is it a free for all and all sites compete for the search traffic as normal? Thanks in advance. Paul

Layered navigation and hiding nav from user agent
I am trying to deal with the duplicate content issues presented by Magento's layered navigation feature (aka faceted navigation). I installed Amasty's Improved Navigation extension (https://amasty.com/improved-layered-navigation.html) and it offers the option to hide the layered navigation from specific user agents (ie googlebot, bingbot, etc). This seems like cloaking to me and I hesitate to try it, unless hiding faceted navigation from specific user agents is known to be acceptable to Google (white hat practice). Does anyone know if this the case?

Pitfalls when implementing the “VARY User-Agent” server response
We serve up different desktop/mobile optimized html on the same URL, based on a visitor’s device type. While Google continue to recommend the HTTP Vary: User-Agent header for mobile specific versions of the page (http://www.youtube.com/watch?v=va6qtaiZRHg), we’re also aware of issues raised around CDN caching; http://searchengineland.com/mobile-site-configuration-the-varies-header-for-enterprise-seo-163004 / http://searchenginewatch.com/article/2249533/How-Googles-Mobile-Best-Practices-Can-Slow-Your-Site-Down / http://orcaman.blogspot.com/2013/08/cdn-caching-problems-vary-user-agent.html As this is primarily for Google's benefit, it's been proposed that we only returning the Vary: User-Agent header when a Google user agent is detected (Googlebot/MobileBot/AdBot). So here's the thing: as the server header response is not “content” per se I think this could be an okay solution, though wanted to throw it out there to the esteemed Moz community and get some additional feedback. You guys see any issues/problems with implementing this solution? Cheers! linklater

My website (non-adult) is not appearing in Google search results when i have safe search settings on. How can i fix this?
Hi, I have this issue where my website does not appear in Google search results when i have the safe search settings on. If i turn the safe search settings off, my site appears no problem. I'm guessing Google is categorizing my website as adult, which it definitely is not. Has anyone had this issue before? Or does anyone know how to resolve this issue? Any help would be much appreciated. Thanks
