Do Search Engines Care About Valid HTML?

Tuesday, October 13th, 2009

Like most web developers, I?ve heard a lot about the importance of valid html recently. I?ve read about how it makes it easier for people with disabilities to access your site, how it?s more stable for browsers, and how it will make your site easier to be indexed by the search engines.

So when I set out to design my most recent site, I made sure that I validated each and every page of the site. But then I got to thinking ? while it may make my site easier to index, does that mean that it will improve my search engine rankings? How many of the top sites have valid html?

To get a feel for how much value the search engines place on being html validated, I decided to do a little experiment. I started by downloading the handy Firefox HTML Validator Extension (http://users.skynet.be/mgueury/mozilla/) that shows in the corner of the browser whether or not the current page you are on is valid html. It shows a green check when the page is valid, an exclamation point when there are warnings, and a red x when there are serious errors.

I decided to use Yahoo! Buzz Index to determine the top 5 most searched terms for the day, which happened to be ?World Cup 2006?, ?WWE?, ?FIFA?, ?Shakira?, and ?Paris Hilton?. I then searched each term in the big three search engines (Google, Yahoo!, and MSN) and checked the top 10 results for each with the validator. That gave me 150 of the most important data points on the web for that day.

The results were particularly shocking to me ? only 7 of the 150 resulting pages had valid html (4.7%). 97 of the 150 had warnings (64.7%) while 46 of the 150 received the red x (30.7%). The results were pretty much independent of search engine or term. Google had only 4 out of 50 results validate (8%), MSN had 3 of 50 (6%), and Yahoo! had none. The term with the most valid results was ?Paris Hilton? which turned up 3 of the 7 valid pages. Now I realize that this isn?t a completely exhaustive study, but it at least shows that valid html doesn?t seem to be much of a factor for the top searches on the top search engines.

Even more surprising was that none of the three search engines home pages validated! How important is valid html if Google, Yahoo!, and MSN don?t even practice it themselves? It should be noted, however, that MSN?s results page was valid html. Yahoo?s homepage had 154 warnings, MSN?s had 65, and Google?s had 22. Google?s search results page not only didn?t validate, it had 6 errors!

In perusing the web I also noticed that immensely popular sites like ESPN.com, IMDB, and MySpace don?t validate. So what is one to conclude from all of this?

It?s reasonable to conclude that at this time valid html isn?t going to help you improve your search position. If it has any impact on results, it is minimal compared to other factors. The other reasons to use valid html are strong and I would still recommend all developers begin validating their sites; just don?t expect that doing it will catapult you up the search rankings right now.

Top 5 Ways To Get Inbound Links

Friday, September 25th, 2009

I’ve listed the methods below in the order you should use them: from the beginning (things you should do when you first start out a site) to the advanced methods, the ones you should use when your site is a little bit older and you’re already getting a fair amount of visitors.

Before we get down to business, I have to tell you this very important detail: don’t start promoting your site until it has some content - it’s unlikely that you’ll get good results when you promote an empty site!

1. Directory submissions - this is a very important step for a new site, because this is probably how search engines will first find you. What you will need:

* 5 different versions (except for the site URL) for each of the following: site URL, title, description, list of keywords.

* an email address, specially created for directory submissions. This email should be on the domain of the site you are submitting or else it will be rejected by some directories.

* a list of seo-friendly directories - http://info.vilesilencer.com/main.php?rock=seo-friendly.php has one of the best lists of seo-friendly directories.

Now here comes the hard part: take that directory list, visit each directory and submit your site cycling your titles and description on each submission. This is the hardest part mainly because of the amount of workload - don’t worry, this can be made bearable by using 2 utilities: Roboform (www.roboform.com - which you can use with Internet Explorer and Firefox that has free and paid versions) and Informenter (https://addons.mozilla.org/firefox/673/ - a Firefox only plugin).

2. Reciprocal links (link exchanges) - I personally don’t use this method anymore because it’s too much work and there are not enough rewards! Link exchanges used to be a very powerful method in the beggining of Google and PageRank, but not anymore. This doesn’t mean that reciprocal links don’t work anymore, it’s just that they’re not that important anymore.

However this is one step you could follow when you have little competition, somewhere in the range of 300 000 or 400 000 results for your search word or phrase.

3. Reprint rights articles (submitting articles to article directories) - this is one of my favorite methods of obtaining backlinks: it requires little time, it’s free and you can (possibly) get a lot of return on your investment!

Writing articles gives you perfect control over the enviroment your links are in, and even a little control over the site where your article resides (considering the fact that webmasters usually post only articles that have the same topic as their site). Writing articles of high quality will ensure that your articles will be posted on many sites - a good article will get you a good number of backlinks!

One last thing about article writing: never, and I mean never post the article that you’ll distribute on your own site! Considering the article could appear on very important sites, Google may apply a duplicate content filter on your site, thus possibly burring it in the SERPs. Your site should be as clean as a whistle, with as much original content as possible.

4. Buying links - in my opinion, if you are not an expert in search engine optimization you should not try buying links to improve your rankings. There are a lot of factors to take into account when looking to buy links: theme of the site, the traffic that the page or site gets, whether that traffic is from natural and sustained (not from PPC, traffic exchanges or such methods), PR, anchor text and many more!

However, if you decide on buying text links on other sites, do the following:

* choose well established sites that have the same theme as yours.
* the link should be spiderable: check the robots.txt file, nofollow metatags and the rel=”nofollow” link atribute.
* make the link look as different as possible from a bought link: surround it with text and avoid placement in the site’s footer or in an “Advertisements” or “Partners” box.

5. Link baiting is one of the most powerful method of online promotion, but this should be used only when your site is a little bit older and stable - getting a lot of links in a short time span can actually hurt your site.

There are a few hooks that you can use to attract links:

* news: get an important story first and you could be the focus of your industry sector, even if for only a few hours! People are always on the look-out for fresh stuff, and if it’s good you could end up with a lot of backlinks.

* resource: gathering a list of useful pages in your industry, or maybe offering a new viewpoint on a certain research paper.

* controversy: this kind of link baiting can actually get you on the wrong side of some people because it requires contradicting a popular point of view or an authority figure. So tread carefully!

Are Cookies Evil? What Service Do Cookies Perform In A Web Browser?

Sunday, July 5th, 2009

Are cookies are bad and do they invade your privacy? We’re not talking about the kind of cookie you eat, we’re talking about computer cookies! It’s not really true that cookies are evil.

So, what is a cookie, what’s it made of and what does it do? A cookie is a tiny text file that a web site can put on your computer as you browse the pages on that web site. One thing people don’t understand is that a web site can only read and write its own cookies, it cannot access another web site’s cookies. Cookies are used for storing various items of information, such as a name, or a selection choice you made. This information will be read back from the when you load other pages on the site, or, on return visits to the site.

What reason does a web site need to use cookies? Web browsers are stateless, stateless means that as you through various pages on a web site, each of those pages is a separate and distinct action. For example, the web server does not know it’s the same person that was on the home page that made the request for the order page. This is very different from desktop applications like Microsoft Excel that you run on your computer. The web server sees all page requests as individual requests for pages, not as a continuous visit from you. As you move through a web site and select things and make choices, what keeps you from having to reenter or reselect that information as you load each page? Usually the answer is a cookie. A cookie can be used by the web server to keep track of you as a user so that as you navigate from page A to page B, the web server knows it’s you and the developer of the web site can reference those items stored in your cookie to maintain a stateful experience for your session or visit to the web site.

Occasionally, you may want or need to delete your cookies.

You can delete your cookies a few ways. Most web browsers (Microsoft Internet Explorer, Netscape, FireFox, Opera,

etc.) have different ways to do this, so consult the help for your browser on how to delete the cache files and cookies. There are also several software packages to clean your PC and these packages also delete cookies.

Using cookies improves your user experience when browsing the Internet. Is there a security risk or danger to cookies? A web site can use cookies for saving information that you enter into forms on web pages and that’s where security concerns arise. Usually this never causes any problem, however, before letting someone use your computer, or taking your computer somewhere to be repaired or serviced, always delete your browser’s cache AND cookies!
Each browser is different, so consult your help files for the browser you use (Microsoft Internet Explorer, Netscape, FireFox, Opera, etc.) for how to delete the cache files and cookies.
