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://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

An immediate and long-term plan for expired Events?
Hello all, I've spent the past day scouring guides and walkthroughs and advice and Q&As regarding this (including on here), and while I'm pretty confident in my approach to this query, I wanted to crowd source some advice in case I might be way off base. I'll start by saying that Technical SEO is arguably my weakest area, so please bear with me. Anyhoozles, onto the question (and advance apologies for being vague): PROBLEM I'm working on a website that, in part, works with providers of a service to open their own programs/centers. Most programs tend to run their own events, which leads to an influx of Event pages, almost all of which are indexed. At my last count, there were approximately 800 indexed Event pages. The problem? Almost all of these have expired, leading to a little bit of index bloat. THINGS TO CONSIDER A spot check revealed that traffic for each Event occurs for about a two-to-four week period then disappears completely once the Event expires. About half of these indexed Event pages redirect to a new page. So the indexed URL will be /events/name-of-event but will redirect to /state/city/events/name-of-event. QUESTIONS I'M ASKING How do we address all these old events that provide no real value to the user? What should a future process look like to prevent this from happening? MY SOLUTION Step 1: Add a noindex to each of the currently-expired Event pages. Since some of these pages have link equity (one event had 8 unique links pointing to it), I don't want to just 404 all of them, and redirecting them doesn't seem like a good idea since one of the goals is to reduce the number of indexed pages that provide no value to users. Step 2: Remove all of the expired Event pages from the Sitemap and resubmit. This is an ongoing process due to a variety of factors, so we'd wrap this up into a complete sitemap overhaul for the client. We would also be removing the Events from the website so there are not internal links pointing to them. Step 3: Write a rule (well, have their developers write a rule) that automatically adds noindex to each Event page once it's expired. Step 4: Wait for Google to re-crawl the site and hopefully remove the expired Events from its index. Thoughts? I feel like this is the simplest way to get things done quickly while preventing future expired events from being indexed. All of this is part of a bigger project involving the overhaul of the way Events are linked to on the website (since we wouldn't be 404ing them, I would simply suggest that they be removed entirely from all navigation), but ultimately, automating the process once we get this concern cleaned up is the direction I want to go. Thanks. Eager to hear all your thoughts.

Do long UTM codes hurt SEO?

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

How do you build your pre-sales seo audit
Hello Moz community, I'd like to know if you build "pre-sales seo audit" when selling your services to a prospect.

If you know ressources i should read as regards to mini seo audit / pre-sales seo audit just paste the link 🙂 Thanks for your answers

Expired domain 404 crawl error
I recently purchased a Expired domain from auction and after I started my new site on it, I am noticing 500+ "not found" errors in Google Webmaster Tools, which are generating from the previous owner's contents.Should I use a redirection plugin to redirect those non-exist posts to any new post(s) of my site? or I should use a 301 redirect? or I should leave them just as it is without taking further action? Please advise.

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.

What is the best website structure for SEO?
I've been on SEOmoz for about 1 month now and everyone says that depending on the type of business you should build up your website structure for SEO as 1st step. I have a new client click here ( www version doesn't work)... some bugs we are fixing it now. We are almost finished with the design & layout. 2nd question have been running though my head. 1. What would the best url category for the shop be /products/ - current url cat ex: /products/door-handles.html 2. What would you use for the main menu as section for getting the most out of SEO. Personally i am thinking of making 2-3 main categories on the left a section where i can add content to it (3-4 paragraphs... images maybe a video).So the main page focuses on the domain name more and the rest of the sections would focus on specific keywords, this why I avoid cannibalization. Main keyword target is "door handles" Any suggestions would be appreciated.
