              Thanks! 🙂

              Typically these blacklists are created and maintained by security specialists who have done testing on the different bots to determine which are legit/beneficial and which are crapbots. They then provide these lists for others to use. Often the lists are amalgamations of bots detected and analysed on a number of different sites and by a number of different specialists to act as a double-check for each other.

              You do need to be careful that you are using a well-curated list, as carelessly blocking bots can cause problems for legitimate bots. You would check out the creator of such a list the same way you'd check out the creator of a plugin you're considering using - check reviews, look at comments and responses on the post that provides the blacklist etc.

              That answer your question?

              Paul

                Hi ThompsonPaul,

                Wow! Superb explanation. One thing I just want to clarify, how would I know if these bots are "bad bots".

                Thanks a lot! 🙂

                  As Lynn mentions, these entries form a blacklist for "bad bots". These are bots that are identified as being harmful (or at least non-helpful) to the real use of a website. Bots are essentially spiders that crawl and record the pages of your site the same way the GoogleBot does.There are 2 main reasons for blocking them

                  1. Too many unnecessary bots can put a real strain on server resources, causing the site to slow down for real users. This can be especially problematic with bad bots as they do not respect the entries in your robots.txt file and so will crawl even blocked pages. This can mean huge numbers of extra pages get crawled, leading to even more load.

                  2. Many (most?) of these bots are collecting data for nefarious purposes. Some are scrapers to collect your site content in order to re-use it illegally on another site, some are scanning for certain files/plugins on your site known to be insecure so they can target them for attack, etc.

                  Best case scenario, these bots waste your bandwidth and can cause site slowdowns on low-powered (e.g. shared) servers. Worst case, they can actually cause harm to your site.

                  There are literally many thousands of these types of bots out there, and their creators often change their identifying user agents just to get around these types of blacklists. But many have been around for some time and still use the same identifier. So having a blacklist to block the most common of them is actually very good security practice. To be totally proactive however, you'd need to update the list every couple of months.

                  Bottom line - those entries are providing some security and overload protection for your site, and there's essentially no downside to having them in place even if they're not catching everything.

                  Hope that helps - if any of my explanation isn't clear, just holler 🙂

                  Paul

                      I dont use something like this myself. I suppose if you are having some problem with bots it might be useful, maybe someone else can chime in if they have some experience with this kind of blocking.

                        Thanks Lynn! Is this really necessary?

                          HI,

                          It is checking to see if the visiting user agent contains any of these strings (NC is telling it non case sensitive) and if it does to return a 403 forbidden message.

                            Why do people put xml sitemaps in subfolders? Why not just the root? What's the best solution?

                            Just read this: "The location of a Sitemap file determines the set of URLs that can be included in that Sitemap. A Sitemap file located at http://example.com/catalog/sitemap.xml can include any URLs starting with http://example.com/catalog/ but can not include URLs starting with http://example.com/images/." here: http://www.sitemaps.org/protocol.html#location Yet surely it's better to put the sitemaps at the root so you have:
                            (a) http://example.com/sitemap.xml 
                            http://example.com/sitemap-chocolatecakes.xml
                            http://example.com/sitemap-spongecakes.xml 
                            and so on... OR this kind of approach - 
                            (b) http://example/com/sitemap.xml
                            http://example.com/sitemap/chocolatecakes.xml and 
                            http://example.com/sitemap/spongecakes.xml I would tend towards (a) rather than (b) - which is the best option? Also, can I keep the structure the same for sitemaps that are subcategories of other sitemaps - for example - for a subcategory of http://example.com/sitemap-chocolatecakes.xml I might create http://example.com/sitemap-chocolatecakes-cherryicing.xml - or should I add a sub folder to turn it into http://example.com/sitemap-chocolatecakes/cherryicing.xml Look forward to reading your comments - Luke

                            Ranking 1st for a keyword - but when 's' is added to the end we are ranking on the second page

                            Hi everyone - hope you are well. I can't get my head around why we are ranking 1st for a specific keyword, but then when 's' is added to the end of the keyword - we are ranking on the second page. What could be the cause of this? I thought that Google would class both of the keywords the same, in this case, let's say the keyword was 'button'. We would be ranking 1st for 'button', but 'buttons' we are ranking on the second page. Any ideas? - I appreciate every comment.

                            Partial Match or RegEx in Search Console's URL Parameters Tool?

                            So I currently have approximately 1000 of these URLs indexed, when I only want roughly 100 of them. Let's say the URL is www.example.com/page.php?par1=ABC123=&par2=DEF456=&par3=GHI789= All the indexed URLs follow that same kinda format, but I only want to index the URLs that have a par1 of ABC (but that could be ABC123 or ABC456 or whatever). Using URL Parameters tool in Search Console, I can ask Googlebot to only crawl URLs with a specific value. But is there any way to get a partial match, using regex maybe? Am I wasting my time with Search Console, and should I just disallow any page.php without par1=ABC in robots.txt?

                            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

                            Do 404s really 'lose' link juice?

                            It doesn't make sense to me that a 404 causes a loss in link juice, although that is what I've read.  What if you have a page that is legitimate -- think of a merchant oriented page where you sell an item for a given merchant --, and then the merchant closes his doors.  It makes little sense 5 years later to still have their merchant page so why would removing them from your site in any way hurt your site?  I could redirect forever but that makes little sense.  What makes sense to me is keeping the page for a while with an explanation and options for 'similar' products, and then eventually putting in a 404.  I would think the eventual dropping out of the index actually REDUCES the overall link juice (ie less pages), so there is no harm in using a 404 in this way.  It also is a way to avoid the site just getting bigger and bigger and having more and more 'bad' user experiences over time. Am I looking at it wrong? ps I've included this in 'link building' because it is related in a sense -- link 'paring'.

                            Chinese Sites Linking With Bizarre Keywords Creating 404's

                            Just ran a link profile, and have noticed for the first time many spammy Chinese sites linking to my site with spammy keywords such as "Buy Nike" or "Get Viagra".  Making matters worse, they're linking to pages that are creating 404's. Can anybody explain what's going on, and what I can do?

                            Include Cross Domain Canonical URL's in Sitemap - Yes or No?

                            I have several sites that have cross domain canonical tags setup on similar pages.  I am unsure if these pages that are canonicalized to a different domain should be included in the sitemap.  My first thought is no, because I should only include pages in the sitemap that I want indexed. On the other hand, if I include ALL pages on my site in the sitemap, once Google gets to a page that has a cross domain canonical tag, I'm assuming it will just note that and determine if the canonicalized page is the better version.  I have yet to see any errors in GWT about this.   I have seen errors where I included a 301 redirect in my sitemap file.  I suspect its ok, but to me, it seems that Google would rather not find these URL's in a sitemap, have to crawl them time and time again to determine if they are the best page, even though I'm indicating that this page has a similar page that I'd rather have indexed.

                            Does Google crawl the pages which are generated via the site's search box queries?

                            For example, if I search for an 'x' item in a site's search box and if the site displays a list of results based on the query, would that page be crawled? I am asking this question because this would be a URL that is non existent on the site and hence am confused as to whether Google bots would be able to find it.
