I was just noticing that google and yahoo are constantly spidering my site. Is this nescasary? Should I let them do so or is there a way that I can tone it down a bit? Roger
Yes, it is good and necessary. Just protect your secure areas and stuff you don’t want to be indexed. You may do it with robot.txt file or meta.
For google spider, you can try slow down crawl rate at Google Webmaster Tools (https://www.google.com/webmasters/tools/) if you feel the spider crawl your site too often. It also provide other useful tools. To adjust crawl rate, just go to Diagnostic -> Crawl rate.
Yes I do have fresh content. I have lots of bandwidth so I'm not worried about that. I just noticed that they were there all the time. So I guess it's ok. Thanks. Roger
It certainly causes you no harm. You should be happy the search engines are taking so much interest in your site.
