Do search engines like your Web site?

Written by Paul Silver and David Rosam

Between 75% and 98.8% of visitors to Web sites come from searches made at search engines. If you're going to get high levels of traffic - and hencerepparttar levels of ROI you're looking for - it's very important thatrepparttar 135498 search engines can access allrepparttar 135499 information on your Web site.

Dorepparttar 135500 search engines know about all of your pages?

You can find out which pages on your siterepparttar 135501 search engines know about by using a special search. If you search for 'site:' and your Web site address,repparttar 135502 search engine will tell you all ofrepparttar 135503 pages on your Web site it knows about.

For example, search for: in Google. Yahoo or MSN Search, and it will tell you how many pages they know about.

Ifrepparttar 135504 search engines haven't found some ofrepparttar 135505 pages on your Web site, it is probably because they are having trouble spidering them. ('Spidering' is whenrepparttar 135506 search engine uses an automated robot to read your Web pages.)

Spiders work by starting off on a page which has been linked to by another Web site, or that has been submitted torepparttar 135507 search engine. They then read and follow any links they find onrepparttar 135508 page, gradually working their way through your whole Web site.

At least, that'srepparttar 135509 theory.

The problem is, it's easy to confuserepparttar 135510 spiders - especially as they are designed to be wary of following certain kinds of link.

Links which confuse spiders

If your links are within a large chunk of JavaScript code,repparttar 135511 spider may not be able to find them, and will not be able to followrepparttar 135512 links to your other pages.

This can happen if you have 'rollovers' as your navigation - for instance, pictures that change colour or appearance when you hover your mouse pointer over them. The JavaScript code that makes this happen can be convoluted enough forrepparttar 135513 spiders to ignore it rather than try to find links inside.

If you think your rollovers are blocking your site from being spidered, you will need to talk to your Web designers about changingrepparttar 135514 code in to a 'clean link' - a standard HTML link, with no extra code around it - that is much easier forrepparttar 135515 spiders to follow.

LSI and Link Popularity

Written by Andy Hagans

When Paypal's official Web site no longer ranked #1 in Google on a search for "paypal," it was obvious that Google had become more aggressive in penalizing sites with "unnatural" backlink anchor text. Althoughrepparttar high-profile Paypal example has since been rectified, thousands of webmasters are sufferingrepparttar 135455 consequences of not ranking for even their official company name, let alone their top keywords. It is important for search engine optimizers to understand both how anchor text penalties are being applied and how LSI ensures that anchor text variance will not dilute a link popularity building campaign.

Anchor Text Penalties

Inrepparttar 135456 past year, webmasters have found thatrepparttar 135457 aggressive link popularity building tactics that work well in search engines such as Yahoo! do not fare well in Google. Google has implemented several features to filter out sites that appear to have an unnatural backlink structure; one of these features seems to be specifically penalizing sites with unnatural backlink anchor text.

It has always been an SEO best practice to use descriptive anchor text in both external and internal links. But search engine optimizers have often focused on a single keyword phrase when choosing anchor text, especially if their topic has one keyword that receives vastly more traffic than any secondary keywords. Since good links are hard to come by, they do not want to "waste" any of those backlinks with anchor text that does not contain their main keyword.

The drawback to this approach is that it can be interpreted as unnatural by a search engine. A site with organic, passively-obtained backlinks will have a wide variety of backlink anchor text variations such as: "official site title," "keyword," "keyword synonym," "" and even "click here." Ifrepparttar 135458 vast majority of a site's backlink anchor text is simply "keyword," it is obvious to an algorithm thatrepparttar 135459 link popularity was not obtained organically.

Latent Semantic Indexing (LSI) Basics

Let's now touch uponrepparttar 135460 myth I mentioned before, that if a backlink's anchor text does not contain your Web site's main keyword, its power is wasted. The concept of latent semantic indexing, which may be more fully implemented by major search engines inrepparttar 135461 near future, will prove this myth to be false.
