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
Sam

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?

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!

Does an Apostrophe affect searches?
Does Google differentiate between keyphrase structures such as Mens Sunglasses & Men**'**s Sunglasses? I.e. does the inclusion/exclusion of an apostrophe make any difference when optimising your main keyword/phrase for a page? Keyword explorer appears to give different results..... I.e. no data for Men's Sunglasses, but data appears for Mens sunglasses. So if I optimise my page to include the apostrophe, will it screw the potential success for that page? Thanks 🙂 Bob

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 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!
