      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://moz.com/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

                    Since most UTM codes/URLs are longer than 70ish characters, is this hurting my SEO? If it is, how can I solve the problem while still using a UTM code? Thanks!

                    Loading images below the fold? Impact on SEO

                    I got this from my developers. Does anyone know if this will be a SEO issue? We hope to lazy-load images below the fold where possible, to increase render speed - are you aware of any potential issues with this approach from an SEO point of view?

                    Blocked jquery in Robots.txt, Any SEO impact?

                    I've heard that Google is now indexing links and stuff available in javascript and jquery. My webmastertools is showing that some links are blocked in robots.txt of jquery. Sorry I'm not a developer or designer. I want to know is there any impact of this on my SEO? and also how can I unblock it for the robots? Check this screenshot: http://i.imgur.com/3VDWikC.png

                    Are links in menus to external sites bad for SEO?

                    We're building a blog on a subdomain of the main site. The main site is on Shopify and the blog will be on wordpress. I'd like to keep the user experience as simple as possible so I'd like to make the blog look exactly like the main Shopify site. This means having a menu in the blog that duplicates the Shopify menu. So is it bad for SEO to have someone click on the 'about us' button in the blog subdomain (blog.mainsite.com) which takes you to the 'about us page' on the main shopify website (mainsite.com)?

                    Do rss feeds help seo?

                    If we put relevant RSS feeds on a site, will it help the SEO value? Years ago, I shied away from RSS feeds because they slowed the site down and I didn't like relying on them. However, the past couple years, the Internet has become better, especially in Alaska.

                    Do knowledge base plugins on a subdomain have seo benefit?

                    Hi SEO Moz, We want to use a knowledge base plugin (cheaper & faster than building it ourselves) where we can have Q&As for our website. We want this to help with our SEO by adding in our keyterms that we want to rank for. We've looked into TenderApp & Get Satisfaction which look like good solutions - however, as they're both on a sub-domain do we get any seo benefit from this? When people link to our knowledge base, will this help our website at all - or is the benefit going to go to TenderApp/Get Satisfaction? For instance - Our website URL is http://widget.products.com The KB URL is http://widgetsupport.products.com If the above plugin is not a good solution, is there anything else that is better? Any help will be greatly appreciated!! Thanks.
