Crawling image folders / crawl allowance

[evoNick]

We recently removed /img and /imgp from our robots.txt file thus allowing googlebot to crawl our image folders.  Not sure why we had these blocked in the first place, but we opened them up in response to an email from Google Product Search about not being able to crawl images - which can/has hurt our traffic from Google Shopping.

My question is:  will allowing Google to crawl our image files eat up our 'crawl allowance'?  We wouldn't want Google to not crawl/index certain pages, and ding our organic traffic, because more of our allotted crawl bandwidth is getting chewed up crawling image files.

Outside of the non-detailed crawl stat graphs from Webmaster Tools, what's the best way to check how frequently/ deeply our site is getting crawled?

Thanks all!

I did this accidentally as well recently and had 100% of my products disallowed from google shopping within 48 hours. Sounds like it's not an option. They need the crawl your images folder to make sure you have valid images in you product listings.

if your rankings are improving, then good move!

Hey Richard,

We were previously blocking googlebot from crawling our images at all (through disallowing /img/ and /imgp/ in robots.txt file. We removed this block after recieving this email from Google:

Thank you for participating in Google Product Search. It has come to our attention that a robots.txt file is preventing us from crawling some or all of the images on your site. In order for us to access and display the images you provide in your product listings, we'd like you to modify your robots.txt file to allow user-agent 'googlebot' to crawl your site.

_Failure for Google to access your images may affect the visibility of your items on Google Product Search and Product Ad results. _

While I totally agree that image traffic will not convert like standard traffic, it is free and who knows, we may just pick up a few sales from it.  Of course if this comes at the cost of eating up a disproportionate amount of our crawl allowance relative to the value (or avoiding any penalties from Google Product Search) we'd be better off leaving the block on.

By way of an update, it looks like our rankings have started to improve in Google product search.  We first experienced a drop in rankings and traffic from Product Search on 4/16 and removed the block from robots.txt on 4/22.

Why do you need Google to reach inside your img folder? Images display on the page and are indexed then. Sure, if you are selling images, then I can see the need for this, but to just crawl the img folder??

If it is not huge, I do not see it penalizing you. I would make sure all images are named using keywords as crawling pic001.jpg, pic002.jpg, product01.jpg, logo.gif will not do you any good anyway.

Also I find bad linking coming from Google image searches. No one searches to purchase a coffee cup and looks in Google images to do so. Conversely, if someone is searching images of coffee cups to use in whatever, having them click over to your site is a waste of time. They are just going to grab the image and go leaving your metrics a mess.

I hope that helps.

It may effect crawl allowance but depends on the size of your site, page rank and trust etc.

One of the best ways to determine crawl depth and whether you have any issues is to create separate sitemaps for your most important content or areas of your site. You could also create an image sitemap.

Then you can monitor these over time and and will give you a good picture of which content is being crawled and indexed well and which content/images are not. This may also help you to find out if the site structure is too deep or whether you need to link more to deeper content in order to improve crawling and indexation.

Hope this helps.

Personally, I wouldn't try to figure out the impact by looking at crawl stats.  I'd be more focused on end results.  Have we had an increase in organic traffic, or conversions from Google shopping since we opened it up, or has either of these gone down?

That's what matters, and is the only real indicator as to whether it was a wise move or not.

You could check your server stats on who is accessing your site, this should tell you what bots are going to your pages when. I don't know what control panel you are using for your site, but if you are using Cpanel, I am sure there are tutorials online to help you find this information.
