      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

                    Will skipping <H> tags affect your SEO?

                    seo

                    Will skipping <H> tags on a page have any impact on your SEO, e.g. skipping a <H2> so your page has a <H1> and then goes to a <H3>? Obviously a page must have a <H1>, but does it matter if you skip other headings?

                    Static or dynamic category pages for seo

                    Hi, I'm developing an accommodation site with a limited number of properties in 8 categories.  I had been looking at making the properties blog posts and then using category function to show lists but its going to require a lot of customisation and I have seo concerns about the dynamic content as the category page is crucial. As I don't have a lot to add and listings will remain the same my latest thought was to create all as pages.  However if I create a page with a list of 12 properties on a category page is there anyway of adding some sorting criteria to that page (would be 7 options - swimming pool, near beach, on site creche, budget, mid-range, luxury) Thanks for any tips Neil

                    Target: blank. Does it make an SEO difference?

                    I've notice many sites MOZ included no longer use the target: blank attribute. I think that's what it's called. Basically when a link on your site opens a new tab in the browser as opposed to replacing the browser window you are in.  Given that MOZ think of everything, I would love to hear opinions on this.

                    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)?

                    What are your best tips for SEO on a shopping cart?

                    So, I am working on a shopping cart platform (X-Cart) and so far don't like it. Also, the web designer is not someone I've worked with before and he is understandably conservative about access--which limits what I can and cannot do from the back end. One of the things I like to do is include text for the search engines. However, based on conversion, etc., I think the product images on a landing page (main brand info with specific products that show up) should show up first to move toward conversion first. I am thinking of adding the text below the product images on the brand pages so the viewer sees the products first while still keeping the content seo. My practice is to use between 300-350 words minimum on a page. Just wondering what best practices you have for a shopping cart. Care to share? Any tips or hints? Thoughts on what I might do that would be most effective? As always, thanks in advance for your sage advice!

                    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
