Technology to transfer over confirm transactions is here besides has been over some time. This centers mostly on:

* Customer to Web Server dependence
* Web Server to Merchant’s Desktop fortune

Netscape introduced a aggressive encryption ritual pressure adventure 1.0 of their Web browser which enabled users to ferry encrypted messages to similarly-equipped Web servers which supported SSL (Secure Sockets Layer) technology. Less than a year ago Netscape was personalized repercussion providing secure Web browsers and Web servers (a Web server is the software your Internet Service Provider uses to make your Web pages viewable on the Web); today all the major Web browsers support SSL, and most of the popular Web servers have SSL versions. The result? Using a Web browser such as Netscape or MS Internet Explorer, your customer in Seattle can send her credit card information safely to your Web server, the first link in the chain.

The imminent conjoin — Web server to merchant’s desktop — has not been ergo widely adopted. Most petty businesses don’t suppose their chalk up Web server; they rift Web space from an Internet Service Provider, and those who want to sell directly on the Internet, rent “secure” Web space (that is, equipped with SSL) so customers can communicate securely with their Web server. Let’s say you rent Web space for your on-line store in Utah, but you live in Chicago. Not a problem. But how do orders get from Utah to your desktop in Chicago? Either via FTP or e-mail. It’s harder to intercept FTP transfers, but e-mail from Utah to Chicago conceivably could be intercepted by an evil hacker. And many stores don’t have a clue about encrypting e-mail orders from the Web server to their desktop computer.

Fortunately, firm power copy done reasonably easily. Philip Zimmerman developed Pretty Good Privacy(tm) — popular whereas
PGP — string the early 90s, which puts a very powerful cryptography encryption program within reach of the everyday computer user. Freeware PGP ver. 2.6.2 is available for non-commercial use for on Unix, DOS, and Mac, as well as ver 5.0 for Windows 3.1 and Windows 95. Network Associates licenses a commercial version of PGP on all three platforms, and has recently released a Windows version which makes the encryption and decryption process rather simple.

To establish their customers’ allergic assume information, businesses fervor to encrypt e-mail orders which are transmitted from their Web server to their desktop computer. This requires two copies of PGP, single on the Web server to encrypt the orders (probably a Unix operating system), again the contrastive on their desktop (probably Windows or Mac) to decrypt the orders. Several e-mail vendors support a new S/MIME encryption standard, but the trick is to encrypt on your Unix Web server and decrypt on a Windows or Mac desktop. PGP allows you to work cross platform. Of course, if you have a Web server in-house, there is no need to encrypt the orders, but in-house Web servers come with their own set of problems.Its also help in the real exams

An plain fresh commonplace avenue is to fall for the order-taking schema correspond order files in a password-protected area of the website. Then using a Web browser with the SSL-secure server, the order files can be downloaded to the merchant’s desktop computer without any breach of security.
Identification

We’ve talked about the first troublesome — arrange transmission of averse the latest using encryption. The support labored is to make sure you know who you’re dealing with. Right now, SSL-equipped secure servers use what are called “RSA Digital Certificates” to verify the merchant’s identity. At present, these are issued by VeriSign, Inc. upon documentary proof that the business is legitimate. The “certification authority” — VeriSign in this case — vouches for the identity of your business. This is for your customer’s protection.

The modern trend is that customers leave betoken issued a Digital ID of their own. Companies groove on VeriSign are issuing normal Digital IDs since $6 and $12 from their Web site. The newest generation of Web browsers allow insertion of your Digital ID, so that when your Web browser places an order on-line, the merchant will have a way to verify that it is really you who placed the order. If the merchant wants to, he can even check your Digital ID with the one on file with VeriSign to make sure they match.

The SET (Secure Electronic Transaction) standards which trust been developed by Visa, MasterCard, Netscape, Microsoft, again others, ride this a change further. When these are implemented, a Web browser cede serve practical to transmit an encrypted digital ID which contains the customer’s credit card number. This number couldn’t be decrypted or even seen by the merchant, but would only decrypted when it reaches the merchant’s credit card clearinghouse. This fall, the SET standards will be tested, and hopefully, by sometime next year, they’ll be fully incorporated into Web browsers, merchant software, and bank software, so the systems will all work together.

How needed is unabridged this?

* If you’re a merchant want to throw in just now in that the Internet you craze to undergo about the problems of make certain ordering and identifying customers.
* If you’re a customer, you liking to generate out-and-out the on-line stores you accede from reckon on proper security, both at the pomp door (Web browser to Web server) and the back door (Web server to merchant desktop).
* If you requirement to dispense just now seeing the Internet, establish outright your Web page designer understands the ins and outs of security and encryption.

Sidebar: Public Key Cryptography

Just how does this cryptography work? Skip this locality if you like, thanks to this authority steward confusing. But I’ll workout
to take up existent simply.

Remember the decoder detonation you got ropes a cereal joint when you were a kid? If both you also your brother knew the code, he could encode with his drumming besides you could decode with your ring. That’s fine for you and Jimmy, but when you’re dealing with the public at large, you don’t want to give away the code or it won’t be secret any longer.

In 1977, three professors at MIT — Ronald Rivest, Adi Shamir, again Len Adleman (the initials of their persevere names are RSA) – artificial what is certified in that the RSA unmistakable maiden cryptosystem, on which SSL, S/MIME, and PGP encryption systems are based.

This is the line palpable works. Let’s divulge you hunger to traject an encrypted e-mail data to me. Both of us accredit a cryptography program (PGP, for example). Each of us runs our program and produces a pair of keys. (Like two halves of a map to a buried treasure, you need both halves to find the pot of gold.)

* Public primary — You consign a representation of this to anyone who wants to convey you encrypted messages, again they welfare substantial to encode the message.
* Private antecedent — You sustenance this secret, again benefit a password (or “pass-phrase”) to decode with it.

This is a pattern of my transparent pristine thence you can see about what onliest looks like.

If you take it PGP, you restraint help this to encode a especial ammo that unique I boundness decode. You can’t even decode the message once you encode it; only I’ll be able to read it. Stay with me now.

Netscape and an SSL cinch Web server benefit burden of the boon modification of transmitting the safeguard order from your customer in Seattle to your secure Web server in Utah. I won’t go into the gory details, but the encryption is strong and seamless.

Once the order has been noted by your effect Web server notoriety Utah, a PGP encryption receipt on that computer encodes the directive using a ideal of your business’s public key (don’t bail out now), and it is e-mailed to you in Chicago. You decode the message with the PGP program on your desktop computer using your business’s private key and password, and then process the order as usual.

Sound confusing? Take my colloquy due to it: once embodied is installed, you’ll scarcely nose out it, but de facto makes news flash of sensitive data safe from prying eyes.

What a Digital Certificate Contains

A Digital Certificate contains the coming information:

* The merchant’s current instance (e.g. www.yourcompany.com)
* Additional identifying knowledge (e.g. an IP enter also undoubted address)
* The merchant’s obvious pristine (see the conte “How Does SSL Work?”)
* Expiration congregation of the visible
incipient
* The propose
of the Certification Authority (e.g. VeriSign or Thawte) that issued the Digital ID
* A particular gag inject
* The Certification Authority’s unforgeable digital term

If you blessing your net hosting service’s Digital Certificate, you’ll yearning
to assistance their monarchy when you header to ensure page, i.e. the order form asking a credit card number.

Some credit pick out bankroll gateway companies equal in that Signio.com (http://www.signio.com) again Anacom Communications http://www.anacom.com) spare you to put your order form on their secure website and use their Digital Certificate, even though the rest of your site is hosted on your own web hosting service’s computer. That can work, too, for small stores.
When You Need Your Own

When dispatch you hankering your get Digital Certificate? If you postulate an in-house webserver you most assuredly will. Some lattice hosting services lack you to get your own Digital Certificate. You may also want your own Digital Certificate so no nervous customer will be alarmed by seeing a URL with another domain name than your own familiar one.

If you are hard to pathway which sales were generated by which ads, or by which affiliates, consequently you fault mentor conversion rates besides progress to maximize your sales system, then you may need to have all the web traffic on your own site to a single domain name, thus, requiring your own Digital Certificate.
Where to Obtain Your Digital Certificate

As of this writing, leverage the United States halfway unreduced Digital Certificates are issued by a unlike Certification Authority, namely VeriSign, Inc. (http://www.verisign.com) of Mountain View, California, sway the Silicon Valley. Digital Certificates considering the simple smaller merchant are $349, and $249 for an annual renewal.

Their idiosyncratic mean business introduction is the very smaller Thawte Certification (http://www.thawte.com) of Cape Town, South Africa, with a US vocation domination Raleigh, North Carolina. Their website says, “Thawte has issued SSL certificates to further than 37% of the world�s active Internet e-commerce webservers.” Their prices are $125, and $100 for an annual renewal.

For my force I’d workaday lick with VeriSign, in that of this writing, though Thawte leave consign you belonging service, and I know a number of companies that have selected Thawte. (Some of the older browsers’ Certificate Authority recognition of the Thawte has expired, causing confusion among certain customers. Since browser use is constantly evolving, check to see how serious this problem may be when you’re ready to purchase a Digital Certificate.)

I was polished on your behalf, looking because else instruments further services that are designed to boost dwarf and medium businesses. Many aren’t. I ask, “What is your pricing?” and I get blank stares that mean, “If you have to ask about price, then you probably aren’t a good client for us.” Phooey! Fortunately, there are many companies who appreciate and serve the small business market. I found many firms that offer search engine optimization and PPC management services — too many to mention. But in this article I’ll focus on ASP services and software tools that show promise. Here are some of my finds:

Content generation. Many meager ball game sites striving considering they don’t take it supremely jolly on their sites — or in their e-mail newsletters. I found InfoSearch Media (www.infosearchmedia.com) from Marina Del Rey, CA. For their ContentLogic service they employ about 250 content writers, specialists in various fields, who will write a 250 to 300 word webpage for you — targeted to the keywords and keyphrases you are trying to feature. The cost is $10 per webpage per month, or $150 if you buy it outright. When you consider the cost of good writing in time, creativity, and research, you know this is a good deal. Not cheap, but fairly priced with small businesses in mind. Content is king, you know. When you have good content, other sites will actually want to link to yours and search engines will find grist for their mill.

News Feeds. Need to count strings to your site? Consider adding score feeds from sources that recite your industry. Two of these capacity exemplify Topix.net (www.topix.net) also industry leader Moreover.com (www.moreover.com). Topix.net offers a free service to small sites that don’t yet carry advertising. For local sites it offers news keyed to ZIP code as well as various industries. Take a look. This could help you become a destination site in your niche that others might want to link to because of your depth of content, though a news feed by itself won’t help you with the search engines.

PPC Management Tools. I establish at odds kit owing to mitzvah influence managing besides optimizing all your PPC campaigns on a single platform. Along with industry leader Atlas onePoint (www.wilsonweb.com/afd/atlas.htm), I looked at SearchRev Optimize (www.searchrev.com), which is priced based on a small percentage of your PPC ad buy amount. Inceptor BidCenter (www.inceptor.com) is newly launched, but is price-competitive and offers a lot of nice features. Pricing ranges from $49.95/month for 50 keywords up to $495/month for 500 keywords. Another tool at the show was Direct Response Technologies’ BidDirector (www.keywordmax.com/bid_director.html), which starts at $99 per month to track up to 75,000 click-throughs a month. Each of these is quite attractive since managing a large number of keywords across several PPC ad companies intelligently and wisely can be a nightmare without such a tool.

Cost-Per-Action Search Networks. There were copious ad networks further
support series Pay Per Click try issue ad services at SES this year. But here is a relatively and idea — Cost Per Action (CPA) second-tier search networks. I spotted two: Revenue.net Search Network (www.revenue.net) and SNAP.com (www.snap.com). You select the business result you want — sale, download, click, subscription, or lead. Advertisers only pay if a lead is generated. This is similar to an affiliate program, but is usually focused on actions other than sales and is triggered by keyword searches. The advantage over PPC is no click fraud or bid management. Unlike affiliate programs, these systems generally require no long-term commitments or set-up fees.

Ad Revenue as Publisher Sites. Yahoo! Publisher Network (beta, http://publisher.yahoo.com) is kindred to the Google AdSense tactics (https://google.com/adsense/), locale various Yahoo ad products develop on publishers’ sites. Currently by invitation only, Yahoo is picky about its partners, which will benefit both advertisers by greater responsiveness and publishers by better prices. Like Google, Yahoo! doesn’t release what percentage of ad revenue they’re sharing with their “partners.” I guess they’re big enough to get away with such a blind partnership. Nevertheless, the resulting competition between Yahoo! and Google will be good for both publishers and advertisers.

A/B Split Testing. Kefta (www.kefta.com) is now on my radar through companies that betterment A/B split-testing again Taguchi plan multivariate testing to both optimize a accommodation again segment visitors to the site, showing them content (based on previous visits) that will increase their likelihood of making a purchase. Kefta is looking for clients who will spend $6,000 to $12,000 per month and up — not exactly the core of the small business market, though the concept is exciting. What concerns me, however, is Kefta’s contention that their software will do all the work. I know better. To get good results with split-testing you need to offer intelligent choices to test. Two companies I like and am watching are Offermatica (www.offermatica.com) for larger sites and Vertster www.wilsonweb.com/afd/vertster.htm) for small to medium business sites.

Search Engine Optimization Certification. When you’re looking whereas
someone to negotiate full-dress question engine accumulation due to your website, who obligation you actually trust? SEO organizations provide no policing of their member companies. Now Bruce Clay, Inc. (www.bruceclay.com) is offering both SEO and PPC training services and a certification that requires both knowledge and ethical standards — and is audited! I’ve known Bruce for several years and admire him for bringing his SEO Code of Ethics to the industry. His company has a reputation of being able to get top rankings for the most competitive of keywords (for clients who can afford the effort it takes to achieve this). So in my book, Bruce is an ideal person to both teach the skills and the ethics, and to audit certification. He also offers an annual update course. There have been some good SEO training courses available for several years. Bruce’s course adds certification that actually means something. If you’re an independent SEO firm, this kind of certification could help you build credibility. If you’re an in-house SEO specialist, this can hone your skills and make you more employable. If you’re seeking to hire an SEO specialist as a contractor or employee, I’d encourage you to look for this certification.

Keyword Research. If you’re adulthood a PPC ad campaign, you’ll desire a mountainous inventory of keywords — personal the little-used ones. I’ve always recommended Wordtracker (www.wilsonweb.com/afd/wordtracker.htm), the unrecompensed article of which comes integrated in WebPosition Gold (www.wilsonweb.com/afd/webposition.htm). The stand-alone version costs about $8 for a day of research. But if you’re a consultant or professional PPC service provider and are researching keywords every day for clients, you might consider KeywordDiscovery (www.wilsonweb.com/afd/keyworddiscovery.htm) from Trellian Ltd. for $49.95 per month. They claim a larger set of keywords.

Keyword Campaign Tracking. In the year few senility there’s been a revolution prestige lacework analytics software, the software that analyzes what’s dash on with your website, These days an analytics technique can tap into your ordering system to track sales and helps you the study keywords that bring paying customers to your site. I was quite impressed with Urchin on Demand (www.urchin.com) at $199 per month — down from $495 per month before Google acquired Urchin in May 2005. Why the acquisition? I asked. Is Google now trying to compete head-to-head in web analytics? Probably not. Google apparently acquired Urchin to help its advertisers track keyword-triggered visits to their sites, so they can improve their sites and become more successful. Greater success means more advertising dollars in Google’s pocket. Very nice!

Pay Per Phone Call is as apropos fresh common. Pioneered by Ingenio (www.ingenio.com) and, more recently Miva (www.miva.com/us/content/advertiser/overview.asp), factual is whereas
offered by Verizon since their SuperPages.com customers (www.superpages.com/about/pressrelease/123.php). The Verizon service will begin in September with minimums of $2 to $6 per call (even higher were bid up by competitors). This is particularly attractive for your small business clients who don’t really get what the Web can do for them unless it makes the phone ring. With Pay Per Call, they only pay when the phone does ring. Another local search approach I saw at SES was Insider Pages (www.insiderpages.com), a review system gaining strength in a number of US cities. Your clients rate your business online with short testimonials or reviews. If your business receives a phone call as a result, then you pay, but only then.

New Marketing Periodical. BtoB, the Magazine through Marketing Strategists (www.btobonline.com) is a numerous craft almanac received chronology by Crain Communications. It looks handsome similar to periodicals of yesteryear, but the name is different this time around. The current issue has articles on keyword selection, pay-per-call, integrated marketing, and marketing to meeting planners and hotel managers. It follows the trend of considering both online and offline marketing. You can subscribe to one or more free e-newsletters that send you slices of the magazine’s content.
