Which can Googlebot read better, static or dynamic URLs? [...]While static URLs might have a slight advantage in terms of clickthrough rates because users can easily read the urls, the decision to use database-driven websites does not imply a significant disadvantage in terms of indexing and ranking. Providing search engines with dynamic URLs should be favored over hiding parameters to make them look static
I don't think this question is readily answerable except by anecdotal evidence, since no two pages are "otherwise equivalent" enough to measure in the sense you're asking. Beyond a Google search engineer emerging and divulging the answer, if one exists that's limited to only this property, you're unlikely to get a definitive answer; more likely, you'll get a long stream of most-likelies.
But I do like the suggestion that descriptive URLs improve the user experience; I think that's true with respect to short URLs, definitely (e.g., "/help", or "/ask", etc.). One just has to decide how valuable that benefit is to the project, when weighed against the cost of creating such URL schemes, which can sometimes be pricey; I've had a couple of clients who've spent thousands on exactly this effort, with no measurable effect in search ranking whatever.
All else being equal, both pages will achieve the same pagerank. Pagerank is determined by how many people link to you and what their page rank is. So, it does not affect your pagerank.
But it does affect how high you will end up in the search results. In the search index, not only page rank but also keyword relevance matters. If you have the keywords in your url and someone searches for them, then your page will be more relevant and be higher in the search results. Also, when people link to you then the keyword-rich URLs they use to link to you will also improve your relevance.
Don't stare yourself blind at pagerank. It doesn't matter that much. What matters is that you get found by people. Pagerank is only a small (and ever decreasing) part of that.

In the article:
即使搜索引擎没有为您的网页提供更好的排名，您仍然应该为用户这样做。 SEO 的任何好处都只是为您的网站锦上添花。
SEOmoz 有一篇文章，其中包含对URL 最佳实践的建议以及原因为什么每个对可用性或搜索引擎都有帮助。
Even if search engines didn't give your pages a better rank, you should still do it for the users. Any benefit for SEO is just icing on your site.
SEOmoz had an article with suggestions for URL best practices along with reasons why each is helpful for usability or search engines.
我不认为这个问题很容易回答，除非有轶事证据，因为没有两页“在其他方面是等效的”足以衡量你所问的意义。 除了谷歌搜索工程师出现并泄露答案之外，如果存在仅限于此属性的答案，那么您不太可能得到明确的答案； 更有可能的是，您会得到一长串最有可能的数据。
但我确实喜欢描述性 URL 可以改善用户体验的建议； 我认为对于短 URL 来说确实如此（例如“/help”或“/ask”等）。 人们只需权衡创建此类 URL 方案的成本（有时可能会很昂贵），确定这种好处对项目有多大价值； 我有几个客户在这项工作上花费了数千美元，但对搜索排名没有任何可衡量的影响。

关键词频率和页面排名实际上是SEO的两个主要因素。
因此，在 URL 中包含关键字是可取的。
例如 http://my_site.com/article/keyword 比 http://mysite.com/article/42
Keyword frequency and pagerank are really the two main factors in SEO.
It follows, then, that including keywords in your URLs is desirable.
e.g. http://my_site.com/article/keyword is better than http://mysite.com/article/42
在其他条件相同的情况下，两个页面将获得相同的页面排名。 页面排名取决于有多少人链接到您以及他们的页面排名。 因此，它不会影响您的页面排名。
但这确实会影响您最终在搜索结果中的排名。 在搜索索引中，不仅页面排名很重要，关键词相关性也很重要。 如果您的网址中有关键字并且有人搜索它们，那么您的页面将更加相关并且在搜索结果中排名更高。 此外，当人们链接到您时，他们用来链接到您的关键字丰富的 URL 也会提高您的相关性。
不要盲目地盯着页面排名。 没关系。 重要的是你能被人们发现。 Pagerank 只是其中的一小部分（并且不断减少）。
