Generating a signature and expires in java
-
Hello,
I am developing a tool for my company to get stats from SeoMoz using your API. During development, I have been using the example signature and expires values which are auto-generated for me. Now that testing is complete, my code will need to generate these values. I have been googling looking for a resource demonstrating how to do this using Java, but I have not found a good example. I was hoping that someone at SeoMoz would have a resource or an example that they could share.
The email associated with this account belongs to a non-developer, so if a response is provided via email in addition to the forum, sending it to my email would be much appreciated.
Thank you,
Anthony

Never mind, I have come up with a solution:
package com.yourpackage.signature;
import java.io.IOException;
import java.security.InvalidKeyException;
import java.security.NoSuchAlgorithmException;
import java.util.Date;import javax.crypto.Mac;
import javax.crypto.spec.SecretKeySpec;import org.apache.geronimo.mail.util.Base64; //can be whichever flavor of encoder you'd like
public class SignatureGenerator {
public static final String ACCESS_ID = "member-XXXXXXX";
public static final String SECRET_KEY = "XXXXXXXXXXXXXXXXXXXXXXXXXXx";//expireTime should be in seconds since Jan 1 1970 : new Date().getTime()/1000) + X
public static String generateSignature(String data, String key, String expireTime, String algorithm)
throws InvalidKeyException, NoSuchAlgorithmException, IOException {data += expireTime;
byte[] hmacData = null;
SecretKeySpec secretKey = new SecretKeySpec(key.getBytes("UTF-8"),
algorithm);
Mac mac = Mac.getInstance(algorithm);
mac.init(secretKey);
hmacData = mac.doFinal(data.getBytes("UTF-8"));String encoded = new String(Base64.encode(hmacData));
return encoded;
}public static void main(String[] args) {
try {Long longTime = new Long(new Date().getTime()/1000) + 60;
System.out.println(longTime);
String data = ACCESS_ID + "\n";
System.out.println(generateSignature(data, SECRET_KEY, String.valueOf(longTime), "HMACSHA1"));
} catch (Exception e) {
e.printStackTrace();
}}
}

There has been no response from SeoMoz on this forum or to my email.
Please provide some feedback. I am afraid If I cannot solve this issue I will be forced to cancel our account as it is not practical for me to manually load the sample signature and expired value on a daily basis.

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.

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! ~Dana

E-commerce: Taking care of expired product pages
Hi, I work for an e-commerce company in the fashion sector. As you probably know/can guess it is very popular for bloggers and other influencers to link to our products. But the problem is that our products often have a lifespan of only 2-3 months before they expire. Is the best solution to do a 301-redirect to the closest category page for expiring product pages? To make sure we don't lose these links to 404-pages. Or are there any other good solutions popular among e-commerce companys? Thanks for taking your time!

404 Errors for Form Generated Pages - No index, no follow or 301 redirect
Hi there I wonder if someone can help me out and provide the best solution for a problem with form generated pages. I have blocked the search results pages from being indexed by using the 'no index' tag, and I wondered if I should take this approach for the following pages. I have seen a huge increase in 404 errors since the new site structure and forms being filled in. This is because every time a form is filled in, this generates a new page, which only Google Search Console is reporting as a 404. Whilst some 404's can be explained and resolved, I wondered what is best to prevent Google from crawling these pages, like this: mydomain.com/webapp/wcs/stores/servlet/TopCategoriesDisplay?langId=-1&storeId=90&catalogId=1008&homePage=Y Implement 301 redirect using rules, which will mean that all these pages will redirect to the homepage. Whilst in theory this will protect any linked to pages, it does not resolve this issue of why GSC is recording as 404's in the first place. Also could come across to Google as 100,000+ redirected links, which might look spammy. Place No index tag on these pages too, so they will not get picked up, in the same way the search result pages are not being indexed. Block in robots - this will prevent any 'result' pages being crawled, which will improve the crawl time currently being taken up. However, I'm not entirely sure if the block will be possible? I would need to block anything after the domain/webapp/wcs/stores/servlet/TopCategoriesDisplay?. Hopefully this is possible? The no index tag will take time to set up, as needs to be scheduled in with development team, but the robots.txt will be an quicker fix as this can be done in GSC. I really appreciate any feedback on this one. Many thanks

Will invalid HTML code generated by WordPress affect SEO efforts?
Hi all, I'm new to SEOmoz and SEO in general really. I run a small but well regarded freelance website and graphic design business, and until very recently had an employee who handled the SEO side of things. I'm now looking to step into this role myself and hopefully learn the in's and out's of SEO. I've no doubt there will be much to learn, but the SEOmoz tools and it's community seem excellent and helpful. My question then is basically, if WordPress generated HTML code can have an effect on SEO, when it's reported as invalid by tools such as the W3C HTML validator? I'm used to hand coding the majority of my websites for clients, where creating valid HTML and CSS code is something I can do with relative ease. A new client however wants to use WordPress - for ease of updating the site content themselves. The client does however consider any potential SEO implications to be a very important factor in choosing a hand coded vs. WordPress based website. I am aware that WordPress itself is just a means of generating HTML code, and that to the search engines there is no difference between this and the hand coded websites I usually produce. However if WordPress is generating HTML that is being reported as invalid, would this make the search engines penalise the site? On a second note, will the search engines look negatively on a WordPress site where it is being used as a standard website, and the content may not be updated as frequently, as say, a blog? Thanks for your time, and I look forward to hearing your suggestions.

Expired traffic and 301 value
Hi Folks, Here is our situation we have an old brand domain www.asia-hotels.com >> that was redirecting to>>www.asiahotels.com By mistake, we let that domain expired and only noticed the drop a month later We lost all our pages and this for several weeks Not sure of the exact date but approximately around 24th of December, what a merry Xmas! 😞 Since then we have repurchased the domain, Put back all the pages as they were and re-instated all the 301 redirect as they were. Since that date we haven't seen any uplift in our visits or visibility score. Did we do something wrong with our 301 redirect? I know for sure we used ISAPI rewrite mod for the non www. domain although I am not entirely sure how the www. version has been handled. Is there something we should do at a DNS level to flag the site is back? Should we presetn a reconsideration request? Any help would be greatly welcomed. Thanks for your help. Cheers, Freddy More info I placed a bit more info and the visits graph on my blog: http://www.inmarketingwetrust.com.au/seo-effect-of-domain-expiry-on-301-redirects/ I am not sure if this is due to the fact that some information is cached but when i looked at the site on opensiteexplorer I found that the data is still showing as non redirected sites: http://www.opensiteexplorer.org/asia-hotels.com/www.asia-hotels.com/a!comparison effect-of-301-redirect-expired-on-SERP-visibility-300x204.jpg
