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)

Lost ranking after domain switch
I recently migrated from https://whitefusemedia.com to https://whitefuse.com. The website URL structure and content remained the same and I followed all the best practice guidance regarding checks on the new domain and appropriate 301 redirects. I have seen traffic drop by about 50% and the traffic that is still coming through is mainly coming through links still listed by Google under the old domain (https://whitefusemedia.com). Is this normal? Should I expect to see this bounce back, or is there anything I can do now to regain the rankings?

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!

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

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 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!

Should I import external reviews to my site?
Hi everybody! I manage the website for a financial services company. We have more than 5000 reviews on a user review website. We have the possibility to import and display all these reviews on our site. Is this good for SEO? Will Google find it suspicious that our site suddenly displays a lot of new keyword-rich content? What about duplicate content? Please, share your thoughts. Thanks!
