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

Will skipping <H> tags affect your 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?

# Tag - opacity and SEO impact
Hello,
Technical SEO | | Tiffany_Barn
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?

Changing menus regularly - will this impact SEO
We are working on an internal project, where the website owner is thinking of making regular changes to one or two items on the top level menu. Assuming they redirect the original pages or navigate to them in other ways, is there any other impact on SEO to changing the menu structure? I assume they'd submit new sitemaps after each change. Many thanks Fiona

Replace Header Text With Image
I have a static website that I would like to retheme. I have the mockup, and its spliced. The website holds nice rankings right now, and I want to keep them in place. The one thing that will change with this new design is the header will no longer be text, but instead an image. Is there a way to ensure googlebot still sees the H1 tag header exactly how it is now but use an image for the header instead? I dont want any blackhat tricks that will get me banned. Just wondering if there is a simple way to have googlebot see the header as text (not ALT img txt) so the site does not appear to have changed at all. (It hasnt, I only am changing the graphics and colors of background, and header image for better branding.

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.

200 Redirects for SEO instead of 301
We are working with a company on re-platforming our website. On a call yesterday they outlined a strategy to use 200 redirects for our top keywords instead of 301s. I am not familiar with this type of redirect and was wondering if anyone could provide some more insight.
