      For security reasons we are now routing traffic through an external firewall cum CDN. Our server and domain IPs remain the same, but any request is routed through an external IP, which then forwards the traffic.

      Would our rankings be affected because of IP changes?

      Thanks

      Sam

          Thank you for your answers. yes the sit speed has been affected just a hair - so that TTFB has gone down from 0.45 seconds to about 0.6 seconds - oscillates between A and B (mostly B) in one of the testing sites.

            Site speed impact is where I see this becoming a real problem, unless the setup is done correctly

              Hi Sam. A correctly setup firewall or CDN should not have implications for SEO. If you can share the URL / domain then I can take a look at the specifics, but in principle, you should be fine.

              Things to watch out for:

              1. Site speed impacts - in theory a CDN should generally be good for site speed, but if you didn't select one primarily for this reason, it's something to check
              2. HTTPS - ensure that you keep this consistent through the change
              3. Avoid changing URLs in the process (if you have to, make sure you have redirects set up and treat it like a migration with associated risks)

                How does changing sitemaps affect SEO

                Hi all, I have a question regarding changing the size of my sitemaps. Currently I generate sitemaps in batches of 50k. A situation has come up where I need to change that size to 15k in order to be crawled by one of our licensed services. I haven't been able to find any documentation on whether or not changing the size of my sitemaps(but not the pages included in them) will affect my rankings negatively or my SEO efforts in general. If anyone has any insights or has experienced this with their site please let me know!

                Remove sitemap, effect ranking?

                We are considering to remove our sitemap because it doesn't display the right structure. Will it affect current rankings if we remove the sitemap en continuing without a sitemap? Thanks

                Do Letters With Accents Affect SEO?

                Hi Guys, My company has a franchise of a foreign company that uses an accent/foreign letter in its brand name. We have to refer to this franchise with this symbol on our website to meet their standards. I've done some research on this but its not conclusive, so i was wondering whether anyone here can confirm this for me; Will using the letter with this symbol impair our rankings for this franchise name? Obviously as a UK business people search for this franchise with a regular letter and not the accented one. I would have thought that Google is clever enough to recognise the meaning of the accented letter by now and therefore it wouldn't affect rankings (much). Furthermore, do you think that it would make any difference to use the HTML element to represent the accent rather than copy and pasting the symbol onto our website? I would've thought this would help Google pick it up, but it might not make a difference anyway! Any help is appreciated. Thanks Sam

                Google truncating or altering meta title - affect rankings?

                I have a site that the title tag is too long and the title is simply the name of the site (I think they get it from ODP, not sure) Anyway, the rankings for the home page have dropped quite a bit.  I'm wondering if the change that Google makes affects rankings (i.e. name of site doesn't have all the keywords).

                Bing rank drop off for multiple sites

                Hi Mozzers, Seeing some wacky stuff going on on some sites I manage. In more than a few, the ranking on bing has dropped basically overnight from page one spots to not being found on the first 100 positions. Anyone else seeing similar results? Some of the sites are fairly new, some have been around for ages, some are wordpress, some are not. I've been searching for some news of a big change on bing, but keep reading about bing dropping the thin sites during black friday. In one example, I had the site set up in BWT for a while, and had a look at the data. The reports show that the pages are crawled, the index summary shows pages indexed, and there seems to be no crawl errors, but rankings are absolutely gone. Also, I can't see the sites in bing if I search "site:example.com" in bing. Here's 2 examples, the first would make sense since it's pretty thin as I havent added much content yet: http://homewindowtint.org but this one doesn't make sense to me. Sure there's a few errors, but to be dropped like a rock seems weird http://www.ahmedandsukaram.com

                Subdomain and Domain Rankings

                I have read here that domain names with keywords might add a boost to your search rank For instance using a completely inane example monkey-fights.com might get a boost compared to mfl.com (monkey fighting league)  when searching for "monkey fights" There seems to be a hot debate as to how much bonus the first domain might get over the second, but leaving that aside for the moment. Question 1. Would monkey-fights.mfl.com get the same kind of bonus as a root domain bonus? Question 2. If the answer to 1 above was yes would a 301 redirect from the suddomain URL to root domain URL retain that bonus I was just thinking on how hard it is to get root domains these days that are not either being squatted on etc. and if this might be a way to get the same bonus, or maybe subdomains are less bonus prone and so it would be a waste of time Thanks

                Can hidden backlinks ever be ok?

                Hi all, I'm very new to SEO and still learning a lot. Is it considered a black hat tactic to wrap a link in a DIV tag, with display set to none (hidden div), and what can the repercussions be? From what I've learnt so far, is that this is a very unethical thing to be doing, and that the site hosting these links can end up being removed from Google/Bing/etc indexes completely. Is this true? The site hosting these links is a group/parent site for a brand, and each hidden link points to one of the child sites (similar sites, but different companies in different areas). Thanks in advance!

                Does a CDN affect search rankings?

                I feel kind of stupid asking this, but if i use one it would speed things up quite a bit. It is for a ecommerce website, any guidance on this would be awesome!
