Welcome to the Q&A Forum

not really my point - my point is categorisation on large sites is helpful to search engines and users. WP does this very well and I utilise it a whole bunch on my sites that use WP

two limits to be aware of here

1. Google won't index a sitemap larger than 50mb
2. Google won't index a sitemap of more than 50K urls

There is no need to link in html to your sitemap if you are submitting it by webmaster tools, though a poke can be helpful from robots.txt which would look something like :

Sitemap: http://www.example.com/sitemap.xml

and go under your various statements (should be the last thing)

Hope this helps

shouldn't make a huge difference as long as you have one-site map (in this case) and the urls are all the same - i.e. all http or https addresses you should have no issues.

• though your last line makes me ask if you have two sitemaps, in which case ... why? and do they link to your site in one as http and the other https ? in which case yes get rid of one in favour of the url you want to use.

Few things... make sure you have a sitemap that is always upto date and submitted to search engines - this will encourage them to view your content first and recognise it as belonging to your domain.

In addition to this put links in your content to other parts of your site, if it gets scraped it will probably be with the links in it and so anyone actually wanting real content can get through.

If there are thousands from the same domain coming to your site, disavow the base url and also report that url for spam (it's your copyright). In fact if you notice a small site scraping you, do that after you've tried to contact them.

If this still doesn't stop them look at your logs and see where their crawlers are coming from and block their IP's.

On one of my old site I blocked the whole of China at one point because it was constantly being barraged by scrapers and people trying to guess account passwords.

Hope that helps

As @keri has said, it would be a little odd to do it to all external or indeed internal links. (the later of which would be better suited to having no-index tags on them rather than being no-followed).

In terms of your question, it maybe better phrased as "how can i keep all the link juice and never let it go" ... many people have that question, but it's not a good idea to try and keep link juice / equity.

If you did as you suggest and have all links externally no followed then search engines will see it as some kind of manipulation and if done on a large scale will ignore that command and potentially others across your website. Search engines, like Google, don't look very nicely on manipulation and beyond ignoring your commands you may end up with a penalty.

Search engines look for rounded websites which are both linked to and from, such that they are part of the community and not a silo.

thats not always the case, consider a user may remember a number easier than a url which is descriptive (eg .com/12345 vs .com/this-is-a-blog-post-title-and-url ) however the numbers aren't descriptive and so hold no real seo value

• this said regardless of what option is choosen Google could always decide to prefer another mechanism in ranking for urls - or totally ignore them

Ok generally < so not to miss any questions

The links you describe to some extent could be considered manipulated, unless they were sites previously and have since been redirected - which is perfectly valid. However, if they have always been redirects then they are unlikely to have gained anything from those links - In my experience if someone links to a page which is redirected since existence (and google generally knows this thanks to its vast database) then it is unlikely to pass juice - but as i said if it was say a blog post on another site but the site has since moved it will carry some juice.

If you want to investigate that further nip to http://archive.org/web/web.php and enter the url which is being redirected - go back into its history (across the top) and see if a page exists there or not.

So to your main question, are commentluv links worth it. Basically it's hard to tell whether they or any other comment system offering a similar function are worth it. As with many website comments in general the links maybe set to no-follow and so not worth anything to search engines, but thats not to mean they are totally worthless - people still see and click them.

And finally, my advice is never to just look for one type of link (such as one from commentluv comments) - it's the same with any kind of link, if you manipulate a search engine by biasing towards something hugely their worth to you will diminish and your time wasted.

always look at the bigger picture.

this depends on the size and nature of your site. For instance if you've lots of posts about a topic within your site (say "social media" or "email marketing") it is best to have them as a category and your post title to follow. Otherwise you could have issues in that you end up needing to put "email-marketing" in each post url ... which isn't pretty to do manually

do you mean it creates 5000 new pages?

Little confused by your explanation...

same as with author, you just change ?rel=author to ?rel=publisher and it should be one very page of site as opposed to just articles/blogs with author.

If you are using wordpress and don't fancy editing your theme take a look at Yoast SEO

or use the badge option

https://developers.google.com/+/web/badge/

if many show 1 url as duplicate this could be due to non-ww and www redirect issues or be related to dynamic urls (common for paginated pages)

if these are the case fix the redirect issue to either non-www or www and fit in a canonical tag to paginated pages. (google is your friend for finding code)

I could be wrong on this, but its how I got it to work.

On all pages you should be validated as the publisher (assuming it's your site). and then within each post you are the author.

Tools like Yoast SEO Plugin are great at this kind of thing, as long as you are the sole contributor. Otherwise just add a link to G+ in each bio on a post ending ?rel=author - jobs a good en

I would suggest "flower pots- plastic flower pots with free delivery" ... reasons same as above, though I would suggest possibly using "plastic flower pots with free delivery | brand" to remove the repetition which can often be seen as spamming and keyword stuff especially as you are then likely to use the term again in your meta description and url

The thing to remember is that the HTML version should only ever be used for users and not to redirect robots if they hit a 404 on your .xml file. The reason for this is that search engines may still see the file as 404 after the redirect or a 301 redirect, if the later you then have an issue of search engines thinking it was there but is now the html page. Which of course is not a good thing.

I would advise ensuring the fall back never happens to robots / spiders - if the file is just a 404 SE's will return to it, they may not if it is 301 redirect.

hide it using a robots.txt file - though you could also use the noindex meta tag ... this being said search engines in general recognize sitemap pages and aren't too fussed by them, its a good jumping off point for them to find info.

do the above, if you also want to get rid of the "related videos" afterwards on the embed url add

?rel=0 to the end

it depends what your website is for and also what org info you are showing. In most cases the address from the org can be on all pages but extra info such as opening times and such should be stayed within contact or about pages ... at least in general.

assuming use of wordpress here, if you use the seo plugin YOAST and then go to your categories one-by-one you can edit the descriptions and titles, removing your issue. you can also have the plugin do the work to some extent by exchanging category names into your meta tags but they obviously aren't as good as handwritten descriptions.

Index is the current number of pages in the Google Index, EC is total number of pages crawled (cumulative) over a given period.

Indexed will never be 100% of ever crawled for any site which has had pages removed, moved or url changed - this includes if you tell robots.txt to not index a folder once indexed (these go to ever crawled).

Hope that makes sense

Usually, you will find social media sites (of any type) will give no-follow links. So they don't (in theory) pass link juice - however, they are still helpful for ranking, getting visitors and even getting your site indexed.

The prime example of this is G+, through making sure it's not posted to other social media sites or to a sitemap, it is possible to see that when you make a post on Google+ to a new page or blog within a few hours it get's indexed / a robot visits - this is even faster if people comment about the post and share it. At least in my experience.

As SamCUK says though, build your author profile and show you are a real person with great content and the rest will follow. Great content and good use of social media will mean you will naturally build both follow and no-follow links (as of course does deliberate link building)
