          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

                        # Tag - opacity and SEO impact

                        Hello,
                        I have a query animation 'fade-in-up' on my website: tiffanybarnard.com which moves the H1 tag slightly and fades it in from zero opacity to 1. Will this affect the SEO value of the H1 tag?
                        Thank you!

                        Breadcrumbs on Mobile How important are they for SEO?

                        Due to Poor unsightly look of breadcrumbs and the space it takes up above the fold we only employ breadcrumbs on our desktop version. Breadcrumbs are hidden from view on mobile version. However as mobile first indexing is now in play what technical SEO impacts will this have?    one thing that comes to mind is crawling deeper pages where breadcrumbs made them accessible in less than 3 link clicks?  But i am unsure now of the impacts of not having breadcrumbs visible for mobile version of our site.

                        Query string parameters always bad for SEO?

                        I've recently put some query string parameters into links leading to a 'request a quote' form which auto-fill the 'product' field with the name of the product that is on the referring product page. E.g. Red Bicycle product page >>> Link to RFQ form contains '?productname=Red-Bicycle' >>>> form's product field's default value becomes 'Red-Bicycle' I know url parameters can lead to keyword cannibalisation and duplicate content, we use sub-domains for our language changer. BUT for something like this, am I potentially damaging our SEO? Appreciate I've not explained this very well. We're using Kentico by the way, so K# macros are a possibility (I use a simple one to fill the form's Default Field).

                        Any SEO benefits of adding a Glossary to our website?

                        Hi all, I manage a website for a software company. Many terms can be quite tricky so it would be nice to add a Glossary page. Other than that, I have 2 questions: 1. What would be the SEO benefits? 2. How would you suggest to implement this glossary so we can get as much SEO benefit as possible (for example how would we link, where would we place the glossary in the terms of the sitemap, etc.). Any advice appreciated! Katarina

                        JavaScript page loader - SEO impact

                        Hello all,
                        I am working on a site that has a bizarre page load system. All pages get loaded trough the same Javascript snippet, for example: Changing the values in the form changes the page that is loaded. The most incredible thing is that, against my expectations, pages do get indexed by Google.
                        My question is: "Does loading pages dynamically using JavaScript affect the overall SEO performance?" Why are pages getting indexed? Thank you for shedding light on this.
                        Cheers
                        Luca

                        Non-Existent Parent Pages SEO Impact

                        Hello, I'm working with a client that is creating a new site. They currently are using the following URL structure: http://clientname.com/products/furry-cat-muffins/ But the landing page for the directory /products/ does not actually have any content. They have a similar issue for the /about/ directory where the menu actually sends you to /about/our-story/ instead of /about/. Does it hurt SEO to have the URL structure set up in this way and also does it make sense to create 301 redirects from /about/ to /about/our-story/?

                        Hi there, my company is exploring creating an online magazine built with Adobe's InDesign toolset. If we proceeded with this, could we make these pages "as spiderable" as normal html/css webpages? Or are we limited to them being less spiderable, or not at all spiderable?

                        SEO for User Authenticated Content

                        Hi Everyone - I have a potential client who is seeking SEO for a site that contains about 95% of content only accessible through user authentication . Does anyone have tips for getting this indexed without having to open it up to the public? I was considering adding "snippets" into the robots.txt or creating an additional page with snippets linking to the login page. I'd appreciate any thoughts! Thanks!
