After months without a "visible" update, with data collected about 30 days ago, all Google datacenters show a new PageRank update.

This update has no direct impact on rankings, since the information on the PR Toolbar is outdated, about 3 months, and supposed to be updated every quarter. The PageRank of the sites linking to your site may have changed, therefore affecting your own. One not well understood aspect of PageRank is it scoring. For example, a PR 6 is a numeric score rounded from a value anywhere between 5.6 and 6.9 in the PageRank scale.

Coming back to the fact that this PR update did not affect rankings, an example site was downgraded from a PR7 to a PR4. Both rankings and traffic remain constant. So besides a PR downgrade, that may impact future link building efforts, nothing has changed.

A lot of new sites went from PR0 to PR1 as usual between updates. Also, there was an increase in the numbers of PR2 sites. Most PR3 sites stayed at that level. Some PR4 sites lost 1 or 2 points, and PR5, 6 and 7 sites lost points as well.

But the way to approach link building the natural, proper way remains despite all these adjustments. And still can be done legally without triggering PageRank downgrades like the ones we are seen.

In the previous article on this topic, I covered the main types of links you want to get for your site. On the last part, I will clearly state which types of links to stay away from pursuing, and I will further explain some misconceptions about the good types of links.

Do not do this to your links:

(1) Placing a form on your site and then allowing anyone to add a link to your site using an automated process. If you do not manually approve these links, well, you are asking for “link problems”.

(2) Denying a link based solely on a low or non existing PageRank. What a mistake! PageRank is not only outdated, it is also less relevant that it was in the past.

(3) Sites that exchange links with you, but at a later time they do a “nofollow” on your link, or they just simply take it down.

(4) Sites with faked PageRank. Yes, they are all over. The problem is that you are doing an exchange link or buying a link from a site that doesn’t have the PageRank they claim to (offending domains use a 301 or 302 redirects that point their sites to others with high PR)

This article covers a much discussed topic in the SEO community. Also, clients and often site owners come up with questions about what links to get, and how to get them. Note that I will not consider reciprocal links here, because of better alternatives, because of better alternatives, and because their effectiveness only applies to a small number of sites, who use them under 10% of their overall link ratio. I will review the main types you want to get for your site.

The natural one-way links.
This one is solely based in good content and resources. This is the safest method of link building available as far as search engines, which look at the “intent” of links. But it is also the slowest. If your site is new, then as part of its launch, submit it to niche web directories. Start with a few highly trusted directories, but do not have more than 10-15% of your overall links coming from them. Don't overlook industry-specific directories that may be paid or unpaid. These usually send highly qualified traffic and can be a real bargain. Directories will get you site many natural one-way links, at a natural speed of growth. This combination of type and speed is very beneficial. Look for sites that would benefit from offering users your content.

Yahoo has the second biggest Search Engine Market share. This is why it is important to know the basics of Yahoo SEO. I will review the key areas you should be focusing on if you are targeting their rankings:

Titles: Keep your title tag short (around 5 words) mentioning your target key phrase no more than once. No different than Google here, except by the amount of words.

Descriptions: 15 – 18 words total including your target key phrase at the beginning, keeping the overall text very descriptive. You should include an alternative version of your key phrase as well if possible.

Keywords: Unlike Google, Yahoo still uses this tag as part of their ranking evaluation process. Including the most relevant words to the content of the page at front, make sure additional words are still found within your content for maximum benefit. Keep your tag up to 200 characters in length – without commas. No, they would not look like one word altogether, and this is part of the indexing process anyways, were commas get removed. You can keep a comma delimited version for own SEO tracking.

Headings: H1 and H2 should be used containing the key phrases and to keep the on-topic relevancy of your content.

Topical and Navigational Links: When applicable, use links to other sites that further re-enforce the topical nature of your content. That is the basis of what all search engines perceive as relevant, quality links. These are basically one way links from sites that specialize in content directly relevant to the content on your own website. In terms of navigation, you should link internal pages from a broad topic, to a narrower topic, to a specific topic.

Keywords in URL: Even they don't carry a lot of weight with Yahoo, topical keyword-based filenames can give you additional boost over your competitors, so they should be implemented.
