One day, our team started getting alerts that our client's website doesn't work. It was slow for customers.
We looked at the activity logs and saw that Bingbot was hammering the site:
Website crawlers usually have rate-limiting. Rate-limiting is a feature that makes them slow down if they start breaking the website. But it didn't seem like the Bingbot could sense that it's breaking the site for regular people. Or maybe it didn't work that well. The crawl didn't seem to slow down.
If it was my personal site, the solution would've been simple - just block the Bingbot user agent!
Who uses Bing anyway, right?
Well, people do – About 3%.
Our site was an eCommerce site that maximized SEO. Google was king, but there was still some $$ coming from Bing.
We had to find balance.
How to slow down the Bingbot

We decided to slow down Bingbot's crawling, but still keep it present.
So we simply added this two-liner to the
Crawl-delay: 10 directive tells Bingbot to crawl the site "Extremely slowly."
Couple of days later, Bingbot listened:
Get Google to crawl your site more
Great, Bingbot is down! But isn't the googlebot hammering the site now?
Googlebot is unique amongst crawlers because Google pays attention to load that it's putting on your server:
- If the site responds quickly, the crawl limit goes up
- If the site slows down or responds with a lot of HTTP 500 errors, the limit goes down, and Googlebot crawls less
Even though it was hitting the site more now, we didn't have trouble with the HTTP 500 errors that Bingbot was causing.
Control Google's Crawl Budget for your advantage
Slowing down Bingbot tremendously increased our crawl budget with Google.
Crawl budget is the number of pages Google will crawl on your site on any given day.
More crawling won't necessarily make you rank better on SERP, but it will give you better visibility by making sure crawlers get to your content quicker.
Increased visibility was an advantage for us because we knew we had great content that will rank well.
