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

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!

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!

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

Can too many pages hurt crawling and ranking?
Hi, I work for local yellow pages in Belgium, over the last months we introduced a succesfull technique to boost SEO traffic: we have created over 150k of new pages, all targeting specific keywords and all containing unique content, a site architecture to enable google to find these pages through crawling, xml sitemaps, .... All signs (traffic, indexation of xml sitemaps, rankings, ...) are positive. So far so good. We are able to quickly build more unique pages, and I wonder how google will react to this type of "large scale operation": can it hurt crawling and ranking if google notices big volumes of content (unique content)? Please advice
