Can an external firewall affect rankings?
-
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

Hi, We have the same question and we noticed that ahrefs is blocked. Would you mind looking at our site to see if you see any issues>. www.caffeinemarketing.co.uk thanks

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:
- 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
- HTTPS - ensure that you keep this consistent through the change
- 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)

Page Rank Flow
I wonder if someone can help me understand clearly page rank flow. If we have a website with a Home page, Services, About and Contact as a very basic website and the page rank will flow to each of those pages from the Home page (i'm not including internal linking between pages or anchor text from the home page content - this is a question purely about home page flow via the main navigation). If the Services page had 3 drop down pages. Would the home page rank also flow to each of these or is it going to the Services page which then distributes it to the three drop down. So instead of Home page rank flowing to 3 pages 33% each - it is flowing to 6 pages 16.6% each. Or is it flowing to 3 pages - 33.3% then the Services pages get a third of 33.3% ->10.1% I know this is simplifying it all a great deal- but it is the basic concept I am trying to grasp on this simple example. Thanks

Redirect and ranking issue
Hi there - was wondering whether someone might be able to help. For a period of a day and a half, all the traffic to our website's blog articles were mistakenly being redirected to our homepage. A number of these articles ranked in the top 5 in Google worldwide for their targeted keywords, so this was a considerable amount of organic traffic that was instantly being redirected. It was a strange site glitch and our web team rectified the error, but now all these articles have disappeared from Google rankings (not visible anywhere in the first five pages). I'm presuming this must be linked to this redirect issue - we've been advised to wait and see whether Google restores these rankings, but I'm still concerned as to whether this represents a more serious problem? We have re-indexed the pages we are most concerned about, but am not sure whether there is anything else obvious we should think to do. If anyone has any thoughts, I'd be happy to hear them!

Hosting images externally
In these days of CDNs does it matter for SEO whether images (and PDFs etc.) are hosted off-site? Does it make a difference if images hosted on Flickr, photobucket etc. Thanks

Will a CSS Overflow Scroll for content affect SEO rankings?
If I use a CSS overflow scroll for copy, will my SEO rankings be affected? Will Google still be able to index my copy accurately and will keywords used in the copy that are covered by the scroll be recognized by Google?

Can I remove 301 redirects after some time?
Hello, We have an very large number of 301 redirects on our site and would like to find a way to remove some of them. Is there a time frame after which Google does not need a 301 any more? For example if A is 301 redirected to B, does Google know after a while not to serve A any more, and replaces any requests for A with B? How about any links that go to A? Or: Is the only option to have all links that pointed to A point to B and then the 301 can be removed after some time? Thank you for you you help!

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
