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

Main Site and eCommerce Site URLs for SEO
My client currently has a main website on a url and an eCommerce site on a subdomain. The eCommerce site is currently not mobile friendly, has images that are too small and are problematic - and I believe it negates some of the SEO work we do for them. I had to turn off Google Shopping ads because the quality score was so low. That being said, they are rebuilding a shopping cart on a new platform that will be mobile friendly BUT the images are going to be tiny until they slowly replace images over several months. Would you keep the shopping cart on a subdomain, or make it part of the main website URL? Can it negatively impact the progress we have made on the main site SEO.

Page speed in relation to SEO
I cannot seem to find any information about this, so I thought I would try to get a few people's opinion. How do you think pagespeed is measured in terms of Google using it as a ranking factor? Do you think they use their internal Pagespeed app? Something during the crawl? Your GA site speed?

Duplicat content affecting SEO Rankings
We have one main site called buypropertyanywhere, it is a database it holds all the data for all our property websites. One of our most popular sites is housesalesbulgaria, which takes the data from buypropertyanywhere in regards to bulgarian property and display it. The same with housesalesturkey it takes the data in regards to turkish property and display it. We think because buypropertyanywhere and housesalesbulgaria has the same data it has high duplicate content . We think this is affecting the SEO rankings for housesalesbulgaria. Google is looking at housesalesbulgaria as if a copy of buypropertyanywhere. So therefore should we SEO buypropertyanywhere soley and link it to housesalesbulgaria through the articles and content we put on the site. Thanks in advance for any advice.

Good Seo Titles
Hi. Mybsite is www.theprinterdepo.com and I am trying to find a good template for my product/page titles. Many users search our products by the product model: something like Q2121X. Some other users search by: hp 1320 printer or just 1320 printer. They will almost never search for hp 1320 new, or hp 1320 refurbished. My website is developed in magento, and we have a SEO plugin in which I can put a template for the URL and also a template for the product title. I was thinking for title and URL. title + condition + productmodel However many users search for: "refurbished printers" and maybe its better that our products say something like this: HP 1320 Refurbished Printer, instead of: HP 1320 Printer - Refurbished - Q2121X Please let me know your suggestions.

Frustrating Local Seo Question
I have just lost the top stop on Google Places (Pack 7) for one of my clients. The company that took it came out of nowhere to take the top stop. Now I don't mind getting out ranked when someone has worked hard to out rank me but what is frustrating is this site scores terrible across the board on just about every score that is supposed to determine on and off page ranking factors. The only place it outscores is in the link department but the site is so new there is no data available in OSE. The site has 0's and 1's for PA, MR and MT plus the keyword (kitchen remodeling) that it is taking the top spot for scores and F in the SEOMoz on page report card while the page that I optimized for this very same keyword scores an A. Plus this site has zero citations according to Bright Local Data. What Gives? Here is a little bit of data: Keyword: Kitchen Remodeling My Clients website is http://www.tandmkitchens.com Competitors website: http://www.njkitchendesigns.com I'm kicking his butt in every category except Domain Age and inbound link total, his inbound link total is 409 but it's only from 2 domains.

Geotargeting by IP and SEO
Hi, Part of our site displays localized results based on the user's IP (we get the zipcode based on IP). For example a user in NY would get a list of NY based stores, while a user in CA would get a list of CA based stores. So if CA Googlebot comes to our site, it will get results based on Mountain View CA. Given the pages are generated based on your zip, I'm not sure how we'd indicate to Google that we have results for lots of locations and not just the Googlebot IP locations. (users can change their zipcode, but by default we use geolocation). Our landing pages contain localized content and unique urls with the zipcode etc, but it isn't clear how Google will find results for KY etc.
