How Do Search Engines And Web Crawlers Work



It is the search engines that finally bring your website to the notice of the prospective customers. Hence it is better to know how these search engines actually work and how they present information to the customer initiating a search.

There are basically two types of search engines. The first is by robots called crawlers or spiders.

Search Engines use spiders to index websites. When you submit your website pages to a search engine by completing their required submission page, the search engine spider will index your entire site. A ‘spider’ is an automated program that is run by the search engine system. Spider visits a web site, read the content on the actual site, the site’s Meta tags and also follow the links that the site connects. The spider then returns all that information back to a central depository, where the data is indexed. It will visit each link you have on your website and index those sites as well. Some spiders will only index a certain number of pages on your site, so don’t create a site with 500 pages!

The spider will periodically return to the sites to check for any information that has changed. The frequency with which this happens is determined by the moderators of the search engine.

A spider is almost like a book where it contains the table of contents, the actual content and the links and references for all the websites it finds during its search, and it may index up to a million pages a day.

Example: Excite, Lycos, AltaVista and Google.

When you ask a search engine to locate information, it is actually searching through the index which it has created and not actually searching the Web. Different search engines produce different rankings because not every search engine uses the same algorithm to search through the indices.

One of the things that a search engine algorithm scans for is the frequency and location of keywords on a web page, but it can also detect artificial keyword stuffing or spamdexing. Then the algorithms analyze the way that pages link to other pages in the Web. By checking how pages link to each other, an engine can both determine what a page is about, if the keywords of the linked pages are similar to the keywords on the original page.

The New Age of Search Marketing



One of the more misunderstood parts about the Web environment today is just how much the user is in control. This is a big shift from the world we lived in 10 years ago. All is not lost. Search marketers who embrace this new reality can reap huge rewards.

This week I'll illustrate how the world has changed and problems search marketers must now tackle. Next week we'll talk about how search marketers (and all Web marketers) can capitalize on this new age of marketing.

This shift in control to the consumer has happened for many reasons. Here are three of the most important ones:

1. Consumers Have Much More Choice

We live in a world where there are hundreds of different types of water, or where you need a dictionary to decipher someone's coffee order.

What makes this particularly interesting on the Web is consumers can comparison shop without getting out of their chair. Comparison shopping that involves driving from store to store is hard, and can take a lot of time. Some people will do it, but many others won't.

On the Web, the effort expended to comparison shop is trivial. If you're searching for consumer electronics, many shopping comparison sites will present all your options on a single screen. Since it's so much easier to comparison shop on the Web, more people will do it.

2. Consumers Can Find Reviews Online

Not only can you find product information and comparison shop, you can also find reviews online. Sites like Amazon embed user reviews directly on the pages for each product. You get ratings right there on the same screen as the "click to order" button for the product.

You can also use Microsoft Live Search to get summaries of product reviews directly in your search results. For example, try searching on Sony Digital Camera, and then click on Sony Cyber-shot DSC-100.

You'll notice on the left of the screen a whole set of summaries of user reviews broken out by about 20 different categories -- such as features, price, speed, brand, construction, appearance, battery life, etc. Detailed user reviews are shown in the center column.

Using tools like these make the process of finding out about other people's experiences with a particular product really easy.

3. Consumers Can Find an Audience

Not only can consumers find out what others think, they can let the world know about their experiences. Here's an example -- a video of a Comcast technician sleeping on a customer's couch.

The general notion of a tech sleeping on the couch is troublesome for Comcast, as are the consumer's other negative opinions about Comcast's product and service in the video. More bad news for Comcast: this video has been viewed 1,120,430 times, according to YouTube.

Changing How You Think

It's more critical than ever to understand your customers in great detail. Here are some quick dos and don'ts to guide your thinking:

  1. You can run, but you can't hide. Poor customer service or an inferior product will get exposed for all to see.

  2. You need to be transparent. The new consumer is increasingly unhappy with companies that provide only some of the story, regardless of the reason.

  3. You have to un-bundle. Bundling of products used to be a great way to unload stuff that was hard to sell otherwise, and still get some incremental dollars for it. Unfortunately, this approach isn't going to fly any more.

Impact on Search Marketing

How do these things affect search marketing? It affects the way you put together PPC campaigns, how you structure content on the pages of your sites, and how you pursue link building campaigns.

For example, over-optimized Web sites will draw more criticism than ever before. Capitalizing on some hidden text? Someone will find it and expose it.

Implementing a link building campaign with just a thin veneer of quality content? People will figure this out. Running an affiliate site using the content supplied by the vendor? Very tough to get rankings for those types of sites these days.

Ultimately, search marketers need to understand the bigger marketing picture of the Web and how search engine marketing fits in. Search can no longer be treated as if it exists in a vacuum.

Top 10 Reasons You Must Do SEO



The death knell for search engine optimization (SEO) rings so often and so loud, sometimes intelligent marketers can’t hear themselves think. The latest: “SEO Deadheads” claim personalization is pushing SEOs out the door. Others cry the complexity of universal search, or any number of innovations by the search engines, now makes effective SEO impossible.

Wrong. SEO remains one of the best investments any marketer can make.

Most folks would hold firm to the reason they do SEO: drive relevant traffic to their sites. They hope this relevant traffic will result in more leads and/or more sales. Those are great reasons (and will be part of this list), but there’s a lot more to consider. A whole lot more.

Five reasons SEO rocks PPC:

10. PPC and CPC: Not Your Lenin’s CCCP: Paid Search, AKA PPC or pay-per-click search marketing, is no communist manifesto. Online marketing’s ultimate expression of capitalism may be the pay-per-click auction. It’s as close to a free market free-for-all as you can get, with one exception: marketers buy their way into the GYM (Google, Yahoo!, MSN) and Ask, as well as other major search engines.

So PPC isn’t really a free-for-all. It’s a “free-for-none.”

Companies, large and small, jump into the pay-per-click arena due to its simplicity. It’s easy to choose keywords and bid, bid, bid.

The benefits: advertisers set a monthly budget, choose the text (or creative), and choose landing pages that show up in the SERPs (search engine results pages).

The downside: the rules of paid search are so simple, playing is easy. Many, many companies are already in the game. The more companies involved in the auction, the higher the CPC (cost-per-click) and, in general, the lower the chance for a significant ROI (return on investment).

Moreover, when budget runs out for a given month, advertisers may lose their presence in the search engines.

With organic SEO, Web sites can — and do — show up 24/7/365. While SEO can’t “guarantee” any site owner high rankings in search results, you can spread your presence across a multitude of keywords. As long as sites have pages/content to support selected keywords, SEO can deliver a more consistent presence across all the major search engines.

9. High Cost of Competitive Keywords: If your traffic-driving keywords are highly competitive, “buying” a regular presence on the major search engines may be cost-prohibitive. Outsourced SEO may provide the presence you’re looking for at a fraction of the cost. If that’s an option you’d like to explore, make sure the firms you interview devise a solid strategy to get you where you want to go. Again, though, there are no guarantees in SEO. But, over time, with a diligent plan, some great things can be accomplished.

Companies must measure the success of SEO campaigns by hard metrics: growth in targeted organic search traffic increased number of leads or increases in sales volume, for example. Many clients and prospects, though, tend to gravitate to ranking reports to see how their presence has increased or decreased against a given set of monitored keywords.

8. Ad Blockers Tackle PPC Ads: I was reading this week, in Advertising Age, about Adblock Plus, which blocks not only pop-ups and banners, but paid search ads as well. No question some people just want the editorial. With organic SEO, you’re there. If you think about the adoption rate of pop-up blockers (who, reading this article, doesn’t already have them installed?), then you might want to be a little concerned about the adoption rate of ad blockers now tackling paid search. Certainly, search ads are often relevant and mostly unobtrusive (in my view). However, consider the number of people who download ad blockers and enable the “block all ads” function. Something to think about.

7. Organic Clicks Rule, Naturally: No matter what study you believe — and there are many — a great deal of evidence shows that more people click on organic results than paid placements. Some studies suggest around 60 percent of searchers click on organic results. Others indicate the percentage is much higher. In any event, organic results get the majority of the clicks, which means organic gets you the best results.

6. Search Engine “Seal of Approval”? No search engine gives a seal of approval or endorses any companies that come up in organic search results. Nor do search engine endorse companies that advertise in their paid-search networks. However, when your site ranks high in search engine results, there’s a strong case for user perception of “implied endorsement.” When you advertise in paid search, many — if not most — searchers realize you’ve paid to get your Web site in the sponsored listings. With organic SEO, the user will likely believe in the ability of the search engine indexing to deliver relevant results.

There’s an unspoken consensus that if a search engine ranks your site as relevant, you must be a leader in your field.

  5. ROI: From all of the search engine optimization programs I’ve overseen (I’m guessing that the number is around 250), there have been few that have not generated a positive ROI. For those that didn’t, it was due to a failed business plan or a poor user experience on the Web site. A properly planned and executed search engine optimization campaign generates a terrific return on investment, so long as you plan for search engine optimization to be a long-term commitment and not a three-month tactical strategy.

I could share with you a case study in which one of our clients received almost $ 11,000,000 worth of organic traffic to their site from January to May of this year. And, I should add, they are not in a “popular” space (that is, they’re not selling consumer electronics, or something else with a high number of searches performed against it). I determined this value by looking at the increased number of clicks from organic search, year over year, and valued this by their average CPC from their Google AdWords campaign. And you can be certain that we didn’t charge anywhere near $ 11,000,000 during that five month time period.

4. Interactive PR: Perhaps you’ve had some bad press. Perhaps those mentions are showing up in Google when someone searches for your company name. These things can be addressed. There are search engine optimization methods that can help to push those “bad” results to the second page, and leave positive results on the first page.

A good case study in Interactive PR is Wal-Mart, in which there are Web sites such as walmartwatch.com and wakeupwalmart.com that are not exactly flattering to the company. These Web sites rank within the top  ten results on Google for the search phrase “walmart.” I have witnessed steps taken by Walmart to deal with this issue, but these two Web sites still rank. Through tactics such as creating a charity website (walmart.org could be a Web site set up to speak to their charitable efforts, for example), you can almost assure yourself of having one less of these unfavorable Web sites showing up in the top  ten results.

3. “Unlimited” Clicks: You don’t set a budget, as you would with PPC, and have the budget dry up by the middle of the month only to leave you hanging until the first of the next month. Once you’ve achieved rankings, the clicks just keep on coming. Too often, PPC clients must daypart their efforts or otherwise manage when they will have a presence in the search engines. What about that off chance that a good prospect was searching on a Sunday afternoon? With an organic presence, you will be there 24/7 to capture all the traffic that you can. As mentioned above, there really is no limit  – other than the total number of searches being performed– to how much traffic your site could receive from organic search engine optimization efforts.

2. Production of More Quality Content: The more you focus on organic search engine optimization efforts, the more likely you are to add quality copy to your site, which is good for both SEO and the user experience. Certainly, there’s a balance to be had between having too much and too little content. You do not want the user to get lost in reading or to miss the point of converting into a lead/sale, etc. In some cases, you have to be creative. Including things like tips, reviews, forums, blogs, and other insightful information can be good for the user experience and great for search engine optimization. I’ve witnessed Web sites built with no intention of doing well in the search engines do well due to the fact that they were focused on providing great content for their visitors. These things go hand in hand.

1. Accessibility: A good search engine optimization firm will help you to make your Web site more accessible to those with disabilities (Section 508 compliance), which also makes your Web site more search engine friendly. Part of building an accessible Web site is making sure that internal linking (links within your Web site pointing from one page to another) includes your keywords within the link itself.  A blind person using a screen reader to navigate your Web site will know the link saying, “email marketing services,” is pointing to the page of your site about “email marketing services.”

When you focus on what’s good for visitors (understanding that some of these people may be affected by some form of disability), you will also help your SEO efforts. Conversely, a good search engine optimization firm should be able to assist you in making your Web site Section 508 compliant by making your Web site more search engine friendly.

So, if you didn’t already believe that search engine optimization was a worthwhile investment, you now have a few more reasons for putting in the necessary time/energy/money to help your business grow through SEO.
