      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)

                Company name ranking

                Hi all, I hope somebody can share their thoughts on the below. A web designer launched my client's new website and I have been tasked with the SEO. I was approached with an immediate problem, www.clientswebsite.co.uk was ranking 9th for their company name after being indexed by Google. The search results above www.clientswebsite.co.uk were related to my client but not all, for example a direct competitor was also ranking. I have been working on the SEO for 2-3 weeks and I just managed to get to 3rd position for the company name, and then www.clientswebsite.co.uk disappeared from page 1! And now instead, an irelevant sub page is now ranking for the company name on page 2 (a contact page). I have checked and the home page is still indexed (did a site: check). The only problem software picks up is a redirect chain (http://homepage -> http://www.homepage  -> https://homepage) the web developers said it wouldn't impact rankings (when I asked them to edit the htaccess file to fix it) I've listed below the SEO tasks I completed whilst attempting to rank the company name: I set up analytics and webmaster tools, in which I set up preferred domain (www) Added a sitemap Edited meta data making sure company name was included I contacted the websites above www.clientswebsite.co.uk that were relevant and asked them to place a link linking to their new website, I was successful with a couple of these. I placed www.clientswebsite.co.uk on all of their social media profiles I reformatted headers on their home page, making sure the H1 included my client's company name I found 2 extra versions of my client's home page (not exact copies, but very similar content) that had been published, so I decided to 301 redirect these to the correct home page Activated SSL and forced to HTTPS I would really appreciate it if anyone could share their thoughts here, whether it be explanations or possible solutions Adam

                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

                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

                My Rankings Keep Going Down - Needs some more ideas on why...

                Hi Everyone, I have been working on the website www.PetsSpark.com for a while now. I used to be on the first page for many of my keywords, now I am lucky if i am on the 2nd or 3rd. I stopped my SEO efforts for about 3 months while making changes to the website, its whithin these 3 months that I started dropping from the first page. The biggest thing I notice is the "type" of website now ranking for my main keywords. Mostly Forums, Blogs, or Product Review websites. Take for instance Dog Tear Stain Remover. I used to rank at about #5 for this keyword and now i rank at #20. I'm not sure if my loss of ranking is a combination of things like who Google is letting rank now or if there is something wrong on my website, etc. Can anyone give me a little insight?? Please.... I will also be happy to give more information about what has been going on if needed.

                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

                Does using parentheses affect the crawlers?

                Quick question: if you using a parantheses around a keyword, do search bots still recognize the keyword?  Fox ex: Welcome to a website about the National Basketball Association (NBA). Will the bots recognize that I'm trying to optimize to NBA and not (NBA)?  Is this different for tags vs. actual body copy?

                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!
