      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

            Auto generated meta description tag in Drupal

            Was having issues on Drupal not autogenerating a meta  description tag, but I think I have figured it out. Just to verify, would this piece of code be the meta description tag (reason I ask is b/c it looks a little different than the usual tag I have seen):

            Google Impressions Drop Due to Expired SSL

            Recently I noticed a huge drop in our clients Google Impressions via GWMT from 900 impressions to 70 overnight on October 30, 2012 and has remained this way for the entire month of November 2012. The SSL Cert had expired in mid October due to the notification message for renewal going to the SPAM folder and being missed. Is it possible for an SSL expiry to be related to this massive drop in daily impressions which in-turn has also effected traffic? I also can't see any evidence of duplicate pages (ie. https and http) being indexed but to be honest I'm not the one doing the SEO therefore haven't been tracking this. Thanks for your help! Chris

            ECommerce: Best Practice for expired product pages

            I'm optimizing a pet supplies site (http://www.qualipet.ch/) and have a question about the best practice for expired product pages. We have thousands of products and hundreds of our offers just exist for a few months. Currently, when a product is no longer available, the site just returns a 404. Now I'm wondering what a better solution could be: 1. When a product disappears, a 301 redirect is established to the category page it in (i.e. leash would redirect to dog accessories). 2. After a product disappers, a customized 404 page appears, listing similar products (but the server returns a 404) I prefer solution 1, but am afraid that having hundreds of new redirects each month might look strange. But then again, returning lots of 404s to search engines is also not the best option. Do you know the best practice for large ecommerce sites where they have hundreds or even thousands of products that appear/disappear on a frequent basis? What should be done with those obsolete URLs?

            Using Sitemap Generator - Good/Bad?

            Hi all I recently purchased the full licence of XML Sitemap Generator (http://www.xml-sitemaps.com/standalone-google-sitemap-generator.html) but have yet used it. The idea behind this is that I can deploy the package on each large e-commerce website I build and the sitemap will be generated as often as I set it be and the search engines will also be pinged automatically to inform them of the update. No more manual XML sitemap creation for me! Now it sounds great but I do not know enough about pinging search engines with XML sitemap updates on a regular basis and if this is a good or bad thing? Can it have any detrimental effect when the sitemap is changing (potentially) every day with new URLs for products being added to the site? Any thoughts or optinions would be greatly appreciated. Kris
