I don't know where the right place to post this is in b2evolution forum. EdB, I will address here my understanding of Permalinks and you can please tell me if I am confused.
One thing that I notice with all blogs, whether b2evo or other, is that all search engines generally make a hash of indexing them. This is because most blogs are entered at the latest page and the content of that is ever changing with any post moving to page 2 and page 3 as time goes by. So the poor search engine always discovers a post at a URL that is doomed to become wrong.
I assume that this is at least part of the reason why permalinks were invented. I use them so that I can quote my posts (articles) in places where they may be read for quite some time. This includes usenet groups, technorati, myspace, flickr and stumbleupon. When I have a hit page, giving it a thumbs up in stumbleupon can generate about 500 people coming to see it. If some of them give it a thumbs up then more get sent, and a popular post (article) can get thousands of refers to it in a few days. This is great, but a total disaster if I make more posts and the people coming do not find what the review (associated with the thumbs up) says that they are coming to.
So I am doing my best to make it work for people coming to my site by always quoting permalinks. But the search engines are sending people to the page numbered links that keep on changing - dynamic links are useless when used this way. It means that the searcher has to do another search all over again and is likely to just go away.
I think that there is an answer for this, but it means some sort of standard between the blogs and the search engines. I cannot find any evidence that this is already the case and it surprises me. Please tell me if there is something already in place.
My idea is that blog software should put something on each page that tells the search engine that this page is either a dynamic one or a permanent URL. If it is dynamic then it should include info that the search engine can find to give the permanent URL. It is already there on most pages in most blogs anyway. But the search engines keep sending people to the dynamic pages. And they often quote multiple links that are really all the same page addressed 3 or 4 different ways.
I presume that blog sites like technorati do this better than google. However technorati is not indexing my sites properly. I have my 3 blogs set to ping technorati whenever I make a change. I can also go to technorati and see when it last updated its view of my sites and do a ping if it is out of date. It is still months behind in most cases although the odd post is shown there when I search. But even weeks old posts that were very popular (100s to 1000s of views) are not showing in technorati.
One other slightly related thing. I see that there is a way to get permalinks without the index.php stuff (shorter URLs). What I would like to know is if I start using that will then other old ones continue to work? ... because I have them plastered all over internet ;-)
All the best
