      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

                    SEO - New URL structure

                    Hi, Currently we have the following url structure for all pages, regardless of the hierarchy: domain.co.uk/page, such as domain/blog name. Can you, please confirm the following: 1. What is the benefit of organising the pages as a hierarchy, i.e. domain/features/feature-name or domain/industries/industry-name or domain/blog/blog name etc. 2. This will create too many 301s - what is Google's tolerance of redirects? Is it worth for us changing the url structure or would you only recommend to add breadcrumbs? Many thanks Katarina

                    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

                    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.

                    How to SEO a Website Built off Godaddy?

                    I have a client whose website is built off Godaddy services. I know Godaddy is not the right choice for building a website, but what's done is done. The client has already bought the Godaddy services and there's no way I can tell him to go rebuild his website before we could optimize it for SEO. I'm already facing a lot of challenges while optimizing on-page elements. When I wanted to verify the ownership for Google Analytics and Webmaster Tool via his Godaddy account. the process failed many times. it looks like Godaddy is using some kind of caching not allowing us to modify the codes. For example, I'd applied the site verification codes for Webmasters Tool 48 hours ago, and the metatag for google site verification is not yet updated in the frontend. It's quite frustrating. What would you suggest?

                    Should WordPress themes be hard coded for better SEO?

                    In the interests of making my site faster I have recently come across the suggestion of removing unwanted PHP from my WooThemes WordPress theme. The suggestion is to hard code the choices I have made in the WordPress template to reduce on database calls. Has anyone actually done this to their WordPress theme before and seen any measurable results?

                    Changing DNS -- SEO implications?

                    Hey Moz, We're migrating an old site on an old server over to a new server/DNS. The plan is to keep the same URL structure and reuse our existing URL's. As long as we make minimal changes to each page's content, we should be able to update our DNS entry and get all the pages recreated and assigned to their correct URLs without any reduction in SEO rankings. Is this correct? This site gets a lot of organic traffic and ranks highly on some challenging keywords, so it's key that we retain our rankings as much as possible. I've read that it's wise to lower the DNS time-to-live to one hour, about a day before the move, to help Google crawl the DNS a little quicker. Are there any other recommendations you guys can offer or past experiences?

                    Restaurant menu SEO: PDF or HTML?

                    Is it better to use a PDF or hard code restaurant menus (or any document for that matter) in HTML? I want the content to be indexed and thought PDF was the way to go for several reasons, but I wanted to get confirmation on this before I move forward.
