We're not using any fancy or esoteric techniques for ranking sites. All of the criteria we use could be considered obvious indicators.
All of these criteria are subject to change or adjustment at any time, and this is not an exhaustive list. There are also ranking factors that we do not disclose. We make no promises or guarantees.
Your domain name is important. If it's an exact match for what someone searched for, it's very likely you'll appear at or near the top of search results.
Having a particular keyword in your domain name makes you rank better for that word.
If your domain is one that generates form or email spam, expect to rank lower, or be removed from the index entirely. We have a few honeypot sites that detect these kinds of things and penalize a site for misbehavior. It's very difficult to have this penalty removed, so behave and don't let a security breach make your system part of a spam botnet.
Certain domain extensions are treated as "less credible", such as .biz or .info. Get the .com or ccTLD version of our site name if you can. Hyphens are also better left out of the domain name.
Having a particular keyword in a URL will cause you to rank better for that keyword. You have to balance that with the length of the URL because we subtract points for excessively long URLs. We like it when a URL is something that a Human can be reasonably expected to type without complaining.
We place a little value on having keyword and description META tags. Having them is always better than not having them, but they won't affect your rank much.
It's important. Be accurate/relevant and don't make it ridiculously long.
Page Head Tag(s)
We take these into account. The first one is most important.
These matter. If the keyword or phrase someone is searching for appears once, it's good. If it's there a few times, that's better. If it shows up excessively that's bad.
We include over two dozen languages in the WbSrch database. Each language is a separate site. In order for languages to be properly categorized, you should use correct language tags on your site.
Not tagging the language of your site could cause your site to be categorized incorrectly and not be seen by people who understand its language. Good use of language tags will cause your site to be categorized correctly more quickly.
We admit it, handling multilanguage sites is hard. They're hard to build, and they're hard to organize. Here are some things that might be helpful to know, and they may also apply to other search engines.
These things make a site easy to categorize:
These things make it more difficult to categorize a site:
In addition, if some of your pages are in one of the languages we don't index, but the site itself is multi-language, it's possible the whole site could be excluded from the search index as an "unindexed language" site if it's not set up in an easy-to-categorize manner. If you have a zh.mysite.com and a pt.mysite.com, it'll be easy for us to categorize and keep the languages that we index without excluding the whole site.
Incoming and Outgoing Links
We are using a proprietary link popularity algorithm called WbRank.
Outgoing links currently have no bearing on the ranking of your site and are only used for the discovery of other sites and pages.
In the future we may decide to use linking to sites tagged as "spam" as a negative factor. If we do so, we will not take things like "NOFOLLOW" links into account. Linking is linking.
Cascading Style Sheets (CSS)
We do not read the CSS for a page.
It's a best practice to store your CSS code in external files. This is also relevant because if your page is stuffed with thousands of lines of styles, we might not even reach the actual page content by the time we've read the 30-40 kilobytes that we consider significant for indexing.
Our crawler does not accept cookies. If you require cookies to load the content for your site, it will not index well. Your site will likely show up as something like "Cookies must be enabled to view this site" in search listings, which isn't exactly great for SEO.
Images, Audio, and Video
We do not read the images, sounds, or movies on a page, nor do we index images and rich media. That saves bandwidth on both sides, but if your content is purely images without any explanatory text, your site will not rank well.
Our crawler does not support frames, nor to we have any intention of ever having it support frames. This means that if you're still using frames for your site (you shouldn't be), your site will likely show up as something like "Your browser does not support frames" search listings. Not exactly great for SEO.
Our crawler does not support or recognize Flash content.
We give a tiny boost to secure URLs (https://).
