Are Expires Headers Detrimental to SEO Health?
-
My dev was looking into Expires Headers to increase speed, but she don't know the ramifications behind them for SEO. What I found online is really old: https://a-moz.groupbuyseo.org/blog/expires-headers-for-seo-why-you-should-think-twice-before-using-them
What do SEOs think?
Thanks in advance!

The best way to use expires headers for SEO is to set them to a reasonable value that will balance the need for caching with the need for search engines to crawl your website. A good rule of thumb is to set expires headers for static files, such as images, CSS, and JavaScript, to a long period of time, such as a year. For dynamic content, such as blog posts and product pages, you can set expires headers to a shorter period of time, such as a week or a month. -
No, Expires headers are not detrimental to SEO health. In fact, they can improve your SEO health by increasing your website's loading speed. When a browser loads a web page, it checks the Expires header for each resource on the page to see if it has a cached copy.
If it does, the browser will use the cached copy instead of downloading the resource from the server. This can save a significant amount of time, especially for visitors who are returning to your website.

No, Expires headers are not detrimental to SEO health. In fact, they can have a positive impact on website performance and user experience, which can indirectly affect SEO.
Expires headers are used to instruct the browser to cache specific resources, such as images, stylesheets, and scripts, for a certain period of time. This can significantly reduce page load time and improve website performance, which can in turn improve user experience and engagement.
When users have a good experience on your site, they are more likely to stay longer, share your content, and return in the future. These positive user signals can indirectly impact your SEO rankings by signaling to search engines that your site is valuable and relevant to users.
Therefore, using Expires headers can actually be beneficial to your site's SEO health, as long as they are implemented correctly and not set for too long of a period.

Odchudzanie to proces, który wymaga czasu, cierpliwości i determinacji. Oto kilka ogólnych wskazówek, jak zacząć odchudzanie:Określ cel: Określ, ile chcesz schudnąć i w jakim czasie. Upewnij się, że twoje cele są realistyczne i osiągalne.
Stwórz plan: Stwórz plan żywieniowy i harmonogram treningów. Plan powinien zawierać zdrowe, zbilansowane posiłki i regularną aktywność fizyczną.
Jedz zdrowo: Zdrowe jedzenie to klucz do utraty wagi. Unikaj przetworzonej żywności, fast foodów, słodyczy i napojów gazowanych. Zamiast tego jedz świeże warzywa i owoce, chude białka (np. kurczaka, ryby), pełnoziarniste produkty zbożowe i tłuszcze roślinne (np. awokado, oliwki, orzechy).
Ogranicz spożycie kalorii: Jedzenie mniej kalorii niż potrzebujesz jest kluczowe dla utraty wagi. Skonsultuj się ze specjalistą ds. żywienia, aby określić swoje indywidualne zapotrzebowanie kaloryczne.
Regularna aktywność fizyczna: Ćwicz regularnie, najlepiej co najmniej 30 minut dziennie. Wybierz aktywności, które lubisz, np. bieganie, jazda na rowerze, pływanie, fitness.
Monitoruj postępy: Monitoruj swoje postępy, np. wagę, obwód talii i bioder, i dostosowuj swój plan w razie potrzeby.
Bądź cierpliwy: Odchudzanie to długoterminowy proces. Bądź cierpliwy i nie zniechęcaj się, jeśli wyniki nie są natychmiastowe.
Pamiętaj, że przed rozpoczęciem jakiejkolwiek diety lub programu odchudzania warto skonsultować się ze specjalistą ds. żywienia lub lekarzem.

Hi Dana,
Expires headers and other caching headers can help improve site performance (as you said), and that will be a good thing for SEO. There is no reason to be concerned - they are common headers and there isn't much they could do to have any negative impact on SEO.
Good luck!
Tom

Are on-site content carousel bad for SEO?
Hi, I didn't find an answer to my question in the Forum. I attached an example of content carousel, this is what I'm talking about. I understand that Google has no problem anymore with tabbed contents and accordeons (collapsible contents). But now I'm wondering about textual carousels. I'm not talking about an image slider, I'm talking about texts. Is text carousel harder to read for Google than plain text or tabs? Of course, i'm not talking about a carousel using Flash. Let's say the code is proper... Thanks for your help. spfra5

Craft CMS SEO Resources
I'm just starting out in freelance SEO & I've taken on a client who is using Craft CMS (version 2.0ish) for their site. I am not even close to being competent enough to manually code via Twig, but I had the main developer install the SEOmatic plugin for me. My question from here is - are there any resources or tips I should be aware of starting out? I just started by updating meta title/descriptions via "New Template Meta(s)" but I'm a bit concerned i'm doing the "template path" thing right - I haven't seen any visible changes in browser, and the SERP preview I'm getting is giving me a broken link. But i'm doing a fresh Moz crawl right now to see if the changes took place or not. so 1. Am I on the right track? 2. How long does it typically take for changes to start to show? 3. Is there anything I should be aware of? any follow up questions just let me know, I'll be following this thread!

Changing menus regularly - will this impact SEO
We are working on an internal project, where the website owner is thinking of making regular changes to one or two items on the top level menu. Assuming they redirect the original pages or navigate to them in other ways, is there any other impact on SEO to changing the menu structure? I assume they'd submit new sitemaps after each change. Many thanks Fiona

As the title really, I run www.specialistpaintsonline.co.uk and 6 months ago when I first got it it had bad links which google had put a penalty against it so losts it value. However the penalty was lift in Sept, the site corresponds to all guidelines and seo work has been done and constantly monitored. the issue I have is sales and visits have not gone up, we are failing fast and running on 2 or 3 sales a month isn't enough to cover any sort of cost let alone wages. hence my question can the cms have anything to do with it? Im at a loss and go grey any help or advice would be great. thanks in advance.

Replace Header Text With Image
I have a static website that I would like to retheme. I have the mockup, and its spliced. The website holds nice rankings right now, and I want to keep them in place. The one thing that will change with this new design is the header will no longer be text, but instead an image. Is there a way to ensure googlebot still sees the H1 tag header exactly how it is now but use an image for the header instead? I dont want any blackhat tricks that will get me banned. Just wondering if there is a simple way to have googlebot see the header as text (not ALT img txt) so the site does not appear to have changed at all. (It hasnt, I only am changing the graphics and colors of background, and header image for better branding.

Can local SEO harm national rankings?
Today I met with a firm called Localeze that provides local directory submissions. I understand the importance of this service if your site is competing locally, however I'm not sure the effects of local SEO for a national brand. Our firm gets most of our traffic from across the country, not just one location, and our business is scattered (which is a good thing). We rank for service related keywords that are not tied to a location. We do not show up for local results so our business in our immediate location is weak. We would like to increase our local presence in search engines but I want to make sure that this will not take away from our national presence. Will optimizing a site for local search negatively affect general rankings? Thanks
